Trump says personal lawyer Rudy Giuliani tested positive for COVID-19

U.S. President Donald Trump’s lawyer, Rudy Giuliani, has tested positive for COVID-19, Trump said on Sunday, after a wave of travel by the former New York mayor seeking to persuade Republican state lawmakers to overturn the Nov. 3 election results.

The 76-year-old Giuliani is the latest in a long line of people close to the White House, including Trump himself, sickened in a pandemic that has killed more than 280,000 Americans.

Giuliani did not immediately respond to a request for comment.

Two sources told Reuters that Giuliani was at Georgetown University Hospital in Washington, D.C., on Sunday. One of the sources said he had not been admitted yet. The hospital did not immediately respond to requests for confirmation.

Giuliani has been spearheading Trump’s floundering effort to overturn his election loss to Democratic president-elect Joe Biden through a flurry of lawsuits. Both Trump and Giuliani have repeatedly claimed, contrary to evidence, that the outcome was marred by widespread fraud.

State and federal officials have repeatedly said there is no evidence of fraud on any significant scale.

Giuliani visited Georgia on Thursday, where he has been urging state lawmakers to stop certification of Biden’s win after making similar pleas in Michigan on Wednesday and Arizona on Monday.

Trump and many of his close associates have balked at public health officials’ advice to wear masks and avoid crowds to stem transmission of the respiratory illness, which has roared to record levels in the United States as winter approaches.

Giuliani, who developed an international profile as “America’s Mayor” for his leadership after the Sept. 11, 2001, terrorist attacks, has faced mounting legal troubles during the Trump administration.

Federal prosecutors in Manhattan have been investigating Giuliani’s business dealings in Ukraine, and two associates, Lev Parnas and Igor Fruman, have been charged with campaign finance violations.

Giuliani has not been criminally charged and has denied wrongdoing. Parnas and Fruman have pleaded not guilty.

Marketplace tested over 20 different masks. Here’s what will best protect you and others during the pandemic

Wearing a mask is critical to reducing the spread of COVID-19, but rigorous tests conducted on behalf of CBC’s Marketplace found that while some work very well, others offer little protection from the particles that transmit the novel coronavirus. One type of mask can even spread those particles to others.

Months into the pandemic, there are still no standards for consumer masks. So Marketplace opted to compare more than two-dozen masks to what is commonly considered the gold standard in protecting health-care workers from infectious diseases like COVID-19 — the N95 mask. 

Marketplace purchased the masks in stores and online from a variety of sellers. The masks were also made out of varying materials and featured different designs. 

Marketplace put the masks through the rigorous National Institute for Occupational Safety and Health (NIOSH) standard test, conducted at a lower air-flow regimen to reflect normal breathing. The test is usually reserved for N95s and personal protective equipment (PPE) intended for health-care workers. A standard NIOSH aerosol test measures filtration efficiency, meaning the quantity of particles the mask filters out as the wearer breathes in.

An N95 mask must have a 95 per cent filtration efficiency. 

“This is the benchmark test. And it’s actually useful because it allows us to compare consumer market masks to masks that we know a lot about,” said James Scott, a professor from the University of Toronto’s Dalla Lana School of Public Health. Scott is a specialist in bioaerosols and runs the lab where Marketplace‘s tests were run.

The test pulls a constant breath of air containing tiny salt particles through the mask material. The salt particles are similar in size to particles able to contain the coronavirus that might originate from droplets expelled by an infected person’s breath, cough or sneeze. During the test, samples of air inside and outside the mask are compared to see how effective the mask is at reducing the level of particles.

Previous tests on consumer masks have commonly looked at how masks can help block particles when coughing or sneezing and prevent transmission to others. But the Marketplace test shows that certain materials make some masks better at limiting wearers’ exposure by filtering what they breathe in, Scott said.

“Even fairly low-efficiency masks are actually quite effective at catching much larger particles. But, it takes a really good mask to catch the small ones as well. And we know that the virus will travel not only on the big ones but the small ones as well,” said Scott.

Polypropylene fabric masks as good as N95

Marketplace‘s test found some masks are just as good as an N95 when it comes to filtering out those potentially harmful particles, including one made with something called polypropylene fabric.

Polypropylene fabric, in this case, is a melt-blown, non-woven plastic fabric. Melt-blown, non-woven polypropylene (NWPP) is commonly used in surgical and N95 masks.

The consumer mask Marketplace tested with an inner layer of melt-blown, non-woven polypropylene fabric and outer layers of cotton had filtration efficiency rates as high as an N95. Scott said the combination of multiple materials contributed to the strong result. 

“This is a really good example of multiple layers of different materials combining to make something greater than the sum of the parts,” said Scott.

Blue three-ply surgical-type disposable masks also reported some of the highest filtration efficiency rates in the Marketplace test, which was of no surprise to Scott, as most contain that melt-blown, non-woven polypropylene fabric. 

“It’s this interwoven matrix of fibre. Air needs to travel around each one of those fibres and it meets the next fibre and it needs to bend its path. So as it does that, those fabrics pull out lots and lots of particles,” said Scott.

Two-ply and three-ply cotton masks 

Marketplace also tested a number of cotton masks, including a two-layer, 100 per cent cotton mask, and a three-layer, 100 per cent cotton mask. More layers of cotton didn’t necessarily mean a better mask. The three-layer cotton mask Marketplace tested did not perform well, but the two-layer cotton mask did.

There was also a noticeable jump in filtration efficiency in cotton masks made with a higher thread count.

Masks made with 600 and 680 thread count cotton had filtration efficiencies almost twice that of the other cotton masks tested. Scott said the weave of a fabric is critical when it comes to catching those potentially harmful particles. 

When it comes to cotton masks, Marketplace‘s test suggested the tighter the weave, the better. 

Scott points out that manufacturers of consumer masks are not currently required to disclose details about thread count, and without that information it’s difficult to say for certain what contributed to some cotton masks’ poorer performance.

Masks to avoid

Scott said consumers should avoid wearing valve masks. While they are useful for protecting someone from inhaling paint fumes or when working in a wood shop, they do not help control the spread of the virus.

The reason is simple. 

“Air only moves through the filter part of the mask when air comes in. It doesn’t move through the filter to exhale. It moves through the valve,” he said. “So there’s nothing to intercept those particles that you may be shedding into the environment.”


Although valve masks are not recommended by the Public Health Agency of Canada, some members of the federal security force at Canada’s Parliament in Ottawa were seen wearing them. (CBC)

Transport Canada has banned the wearing of valve masks, as has Via Rail, and airlines such as Air Canada. Toronto, Ottawa Public Health, Hamilton Public Health and the BC CDC all recommend against the use of valve masks.

The Public Health Agency of Canada (PHAC) said: “Masks with exhalation valves are not recommended, because they don’t protect others from COVID-19 and don’t limit the spread of the virus.” 

Despite this, some members of the federal security force at Canada’s Parliament in Ottawa, mandated to provide physical security for parliamentarians, employees and visitors to the parliamentary precinct, have been wearing valve masks while on duty.

In an email, the Parliamentary Protective Service told Marketplace: “The masks issued by the Parliamentary Protective Service (the Service), despite having a valve, meet the criteria outlined by PHAC regarding the appropriate use of non-medical mask or face covering. The Service has since replenished its stock with masks that do not include a breathing valve.”

Other masks to avoid

The neck gaiter-style mask and bandanas were among the poorest performing when it came to filtration efficiency rates. Scott said the thin, porous materials they are made from is likely the reason they did a poor job filtering out any potentially harmful particles, which is made worse by their loose fit.

A two-layer, 100 per cent rayon mask was also among the worst performing masks Marketplace tested for filtration efficiency.

Lack of standards, testing for consumer masks

Physician and infectious diseases specialist Monica Gandhi from the University of California, San Francisco expects mask requirements to be around for the foreseeable future, at least until there is enough of a safe and effective vaccine. 

“I have become more and more convinced that they are one of the most important pillars of pandemic control,” said Gandhi. 

As Marketplace‘s research has found that consumer masks protect the wearer in addition to others, public health agencies recently updated their guidelines to include that messaging.

Last week, Health Canada quietly updated its mask-wearing guidelines, adding “to protect yourself and others.” On Tuesday, the U.S. Centers for Disease Control went further, updating its recommendations in favour of masking by outlining a number of studies that point to masking as drastically reducing transmission of the disease for both the wearer and others.

WATCH | How masks protect not only others, but the wearer, too:

An infectious disease specialist cites research that suggests wearing a mask can lead to less severe illness from COVID-19 by limiting how much of the virus someone inhales. 0:35

“This is an incredibly exciting update from the CDC since messaging that allows the public to know that masks protect you as well as others will be more powerful in convincing skeptics that masks are important in public spaces to slow down spread and disease from COVID-19,” Gandhi said. 

She also made note of research released in September that suggested wearing a mask can lead to less severe illness from COVID-19 by limiting how much of the virus someone inhales.

The CDC did not cite the study in its bulletin. However, Gandhi said there is accumulating data behind this hypothesis.

Regardless, she said: “Stressing that a mask protects you is getting out the same message we have been trying to convey for the past many months of the pandemic — that wearing a mask gives you a sense of control over your own destiny and protection. It is an important message.”

WATCH | These are the most effective face masks:

Marketplace put more than two dozen consumer masks to the test to see which ones do a better job at protecting you and why. 2:12

With rigorous standards in place for medical-grade masks in Canada and around the world, Scott anticipates standards for consumer masks are likely coming as a consequence of the pandemic.

Marketplace asked Health Canada why there is still no guidance on packaging for consumers with respect to mask performance, or best practices for manufacturers looking to make better masks.

Health Canada said that although it has not set out or endorsed any standards for face coverings, it is actively monitoring the development of standards for face coverings and may revise its position when new information becomes available.

Tips for finding the right mask

What to look for.

  • Start with something that fits you properly. Scott said a mask should fully cover your nose and chin, and be as tight fitting as possible around the rest of your face. If your glasses or sunglasses fog up when you are wearing your mask, you should choose another.

  • Scott suggests consumers look for masks made with multiple layers, and that at least one of them be cotton, preferably the highest thread count you can find.

The average person does not need the same level of protection as a health-care worker on the front lines, Scott said, noting that any mask is better than no mask at all.

Melania Trump says son Barron previously tested positive for coronavirus

Melania Trump said Wednesday that her and U.S. President Donald Trump’s teenage son, Barron, tested positive for the coronavirus not long after his parents, but had no symptoms.

She made the revelation in a lengthy note chronicling her personal experience with COVID-19, including being hit with a “roller coaster” of symptoms that she treated naturally with vitamins and healthy food.

Trump said she is now negative and hopes to resume her duties soon.

After she and the president tested positive earlier this month, the White House said 14-year-old Barron had tested negative. Barron later tested positive for the virus but had no symptoms, she said Wednesday, adding that he has since tested negative again.

“Barron’s fine,” the president told reporters as he departed the White House for a campaign trip to Iowa.

After she and her husband first received their positive results, “naturally, my mind went immediately to our son,” Melania Trump said. She said she was relieved when he tested negative at first was worried about the days to come.

“My fear came true when he was tested again and it came up positive,” she wrote in a statement released to social media.

Melania Trump said she was “glad the three of us went through this at the same time so we could take care of one another and spend time together.”

‘Roller coaster’ of COVID-19 symptoms 

Donald Trump has called his bout with COVID-19, the disease caused by the coronavirus, a ” blessing in disguise.” He was hospitalized for three days and treated with various therapies and drugs, including steroids, supplemental oxygen and an experimental antibody treatment.

Melania Trump did not explain why Barron’s positive diagnosis was not made public earlier.

WATCH | Trump claims he’s now immune to the coronavirus after being infected:

Less than two weeks after disclosing his COVID-19 diagnosis, U.S. President Donald Trump returned to campaigning with a large campaign rally in Florida where he boasted about being immune to the virus, mocked Democratic challenger Joe Biden and took aim at his usual targets — the media and China. 3:29

As for her own trials with the disease, the she said she was “fortunate” to have had minimal symptoms, “though they hit me all at once and it seemed to be a roller coaster of symptoms in the days after.”

She described body aches, a cough and headaches, and said she felt extremely tired most of the time.

To treat it, “I chose to go a more natural route in terms of medicine, opting more for vitamins and healthy food,” she said.

She praised the care provided by Navy Cmdr. Sean Conley, the White House physician, and his team, and said it was an “unfamiliar feeling” to be the patient.

“It was me being taken care of now, and getting first-hand experience with all that COVID-19 can do,” she said.

She acknowledged her family was “fortunate” to have received “the kind of care that we did.” She added, “If you are sick, or if you have a loved one who is sick, I am thinking of you and will be thinking of you every day.”

The coronavirus has infected nearly 7.9 million people in the U.S. and killed more than 216,000, according to the latest count from Johns Hopkins University.

Democratic presidential nominee Joe Biden has made the president’s response to the coronavirus pandemic an issue in the presidential campaign.

Most coronavirus patients suffer mild to moderate symptoms and recover quickly, typically anywhere from two to six weeks, according to the World Health Organization, though older, sicker patients tend to take longer to get well.

NASA’s Next-Gen Spacesuit Is Being Tested Underwater

This site may earn affiliate commissions from the links on this page. Terms of use.

NASA is gearing up for a return to the moon, and that’s going to require a whole new wardrobe. After all, astronauts haven’t stepped out on the lunar surface in decades, and spacesuit technology has advanced considerably. To that end, NASA unveiled its next-generation lunar exploration suit earlier this year, and now it’s testing it with the help of an underwater laboratory

We’ve all seen the suits astronauts wore on the Space Shuttle and during spacewalks outside the International Space Station. That suit, known as the Extravehicular Mobility Unit (EMU), doesn’t offer the capabilities NASA wants for the Artemis missions. The new spacesuit, known as the Exploration Extravehicular Mobility Unit (xEMU), will be the first new design for NASA in more than 40 years. It sports a raft of major upgrades over the EMU, including redundant life support, better mobility, and a redesigned communication system. 

Of course, none of that will matter if the suit doesn’t work correctly. While it’s designed for use on the moon, we have to test it here on Earth. That’s where Johnson Space Center’s Neutral Buoyancy Lab (NBL) comes into play. It’s a massive underwater testing facility with a total volume in excess of six million gallons — that’s almost 10 Olympic-sized swimming pools. This allows NASA to simulate low-gravity environments where astronauts can practice a variety of tasks in the xEMU. NASA says these underwater tests are essential because they can replicate the limited mobility of a real mission. 

NASA is also testing the xEMU in the “rock yard” at Johnson Space Center (above). This outdoor facility has several types of simulated terrain including craters, and you guessed it, lots of rocks. This environment helps NASA simulate EVA missions on the lunar surface to ensure the suit can hold up under the strain. NASA’s Aerospace Safety Council believes xEMU development is running on schedule, which is more than we can say for the next moon rocket. 

The xEMU has is a vital piece of the Artemis program, but it has been overshadowed by the delayed Space Launch System. Currently, NASA hopes to have an uncrewed demo launch in late 2021. The first crewed lunar flyby will take place around 2023, and a landing could be as soon as 2024. These dates all assume no further delays. But hey, at least astronauts on the Artemis missions will look good and be more mobile than Apollo astronauts.

Edmonton Oilers defenceman Caleb Jones says he tested positive for COVID-19

Edmonton Oilers defenceman Caleb Jones has acknowledged he tested positive for COVID-19 before training camp.

Jones says he tested positive when he returned to Edmonton from his home in Dallas.

Jones opened his media session on Friday by revealing his positive test. He said he was asymptomatic.

The NHL is not releasing the names of players who test positive for COVID-19, and the league also is no longer revealing the teams in updates on positive tests.

Jones, 23, becomes the second NHL player to acknowledge a positive test in a media interview. Maple Leafs centre Auston Matthews also told reporters he tested positive on the first day of training camp on Monday, weeks after a report in The Toronto Sun on the star’s diagnosis.

Jones said he did his 14 days of isolation before camp started, but was held out of main sessions for the first three days as he tried to get himself back up to speed.

Blue Jays open camp at Rogers Centre amid reports player has tested positive for COVID-19

The Toronto Blue Jays were set to hold a private workout at Rogers Centre on Monday without their full roster due to a reported positive COVID-19 case involving a player who remained at the team’s spring training facility in Dunedin, Fla.

The team would not confirm the latest positive case, which was first reported by ESPN’s Jeff Passan. Multiple media outlets also reported the news.

Most of the Blue Jays arrived in the Ontario capital on Sunday night via a team charter. Those who were in contact with the player did not board the flight to Toronto, Passan said on Twitter.

“The Jays are not commenting on [the ESPN report] other than to confirm that there is another charter flight with players and staff that is scheduled to arrive in Toronto later this week,” Richard Griffin, the Blue Jays director of baseball media, told CBC Sports.


Multiple players and staff members tested positive for COVID-19 last month. The team shut down its Dunedin training complex and personnel at the facility underwent testing per protocols established by the Blue Jays’ medical team and MLB.

Players need to be cleared with two negative COVID-19 tests to join training camp. The team would not confirm how many players had arrived in Toronto, but did say a second charter flight was planned for later this week.

Canada’s lone Major League Baseball team received special permission from government and health authorities last week to train at Rogers Centre. Players and team staff will isolate from the general public in a closed environment at the downtown stadium and hotel attached to the venue.

CBC Sports’ Devin Heroux breaks down the Toronto Blue Jays return to Canada, and how the team and league plans on proceeding ahead of tentative Opening Day. 1:35

The team’s 60-game regular-season schedule, which will likely begin July 23 or 24, was expected to be unveiled Monday evening.

Most teams are expected to play in their home stadiums, but the Blue Jays face an additional hurdle because of border and quarantine rules during the pandemic. The team has said it hopes to play home games in Toronto.

Team president Mark Shapiro recently said that he would “expect a large number of positive tests” as more COVID-19 testing was done as players and staffers reported to camp.

“That’s going to be part of the transition process into creating the closed environment as much as possible around our players,” he said on a June 26 conference call.

There has been a significant uptick in COVID-19 cases throughout parts of the United States in recent weeks, including eyebrow-raising numbers coming out of Florida.

Toronto was 12-6 in pre-season play this year before spring training was stopped in mid-March. The Blue Jays finished the 2019 season with a 67-95 record.

Toronto FC, Vancouver Whitecaps say no one at club has tested positive for COVID-19

Toronto FC and the Vancouver Whitecaps say no one at their club has tested positive for COVID-19.

The Montreal Impact, who announced in mid-April that a club employee had tested positive, did not want to discuss the issue.

“We are not commenting on our results,” a club spokesman said Monday.

Major League Soccer said Sunday that 18 MLS players and six club staff had received positive Polymerase Chain Reaction (PCR) tests prior to travelling to Orlando for the MLS is Back Tournament.

WATCH | Details of MLS’ resumption plan:

All 26 teams will take part in a tournament to be held at the ESPN Wide World of Sports Complex at Walt Disney World Resort in the Orlando area beginning July 8. 1:37

As of Sunday, a total of 668 players had been tested since early June.

COVID-19 testing for MLS players and staff ramped up with the resumption of full team training earlier this month, with more tests mandated on the eve of departing for Orlando. Upon arrival in Florida, everyone is required to immediately take another PCR test and remain quarantined until they receive the results.

The league said 25 of its 26 clubs were able to commence full team training prior to travelling to Orlando for the World Cup-style tournament, which runs July 8 to Aug. 11 at Disney’s Wide World of Sports complex.

The San Jose Earthquakes, the lone team unable to resume full training in their home market due to local health authority restrictions, were the first side to arrive in Florida — touching down last Wednesday.

“Some of the things have taken a little bit to get used to but I already feel like I’m at home here,” San Jose defender Tommy Thompson told a media Zoom call Friday.

“It was a little bit intimidating at first but now guys are already starting to feel more and more comfortable,” he added.

Rising case rate in Florida

The league said Sunday that of the 329 people given PCR tests on-site in Florida, two were positive — both players who had just arrived. Anyone who tests positive while in Orlando is moved to the isolation area of the hotel until they get medical clearance.

Florida reported 9,557 new cases of COVID-19 among state residents on Friday although that number had dropped to 5,409 on Sunday, according to the Florida Department of Health, Division of Disease Control and Health Protection.

Orange County, which includes Orlando, reported 345 new cases among Florida residents on Sunday.

MLS suspended play on March 12, two weeks into the season, due to the global pandemic.
