Trump spends first night at Walter Reed for Covid-19 treatment

Updates on President Donald Trump's coronavirus diagnosis.

President Donald Trump and first lady Melania Trump have tested positive for Covid-19, the president announced early Friday.

Trump was transported by helicopter to Walter Reed National Military Medical Center on Friday evening as a precautionary measure recommended by the president’s physician, officials said, and he is expected to remain in the hospital for a few days.

The president’s doctor said he was administered an antibody cocktail, along with vitamins, and is fatigued with a low-grade fever, while Melania Trump has a mild cough and headache.

Trump becomes the latest world leader to be diagnosed with the virus just weeks ahead of the election and in the midst of a busy campaign schedule for him and Democratic nominee Joe Biden.

RNC chair tested positive for Covid-19 on Wednesday

Republican National Committee Chair Ronna McDaniel tested positive for Covid-19 on Wednesday.

"After a member of her family tested positive for COVID-19, the Chairwoman was tested for the virus," an RNC spokesperson said in a statement on Friday. "On Wednesday afternoon, she got confirmation she was COVID-19 positive. She has been at her home in Michigan since last Saturday.”

Shocked markets swoon on fresh uncertainty

Major indices fell at the opening bell Friday morning after President Donald Trump's diagnosis injected fresh uncertainty into the forecast, driving investors to sell off shares and move to safe haven assets.

The Dow Jones Industrial Average fell by around 375 points, the S&P 500 dropped nearly 1.5 percent, and the tech-heavy Nasdaq composite index fell by over 1.7 percent.

Assets seen as safe havens during volatility rallied, with the dollar and yen rising. Gold initially rose but pared gains to trade at $1,907. Crude oil fell to $37 a barrel.

“The news came as a shock to investors and the uncertainty of what lay next was quickly priced into markets,” wrote Peter Essele, Head of Portfolio Management for Commonwealth Financial Network, in an email.

“It seems reasonable to assume that markets will be on shaky ground throughout October with the perfect storm of a highly contentious election and a pandemic that remains stubbornly at the forefront," Essele said.

But the losses could also be short lived. Trump's positive Covid-19 test could spur action on deadlocked bills to inject new rounds of coronavirus stimulus, according to Jamie Cox, Managing Partner for Harris Financial Group.

Trump experiencing 'mild symptoms' after testing positive for Covid-19

From masks to disinfectants: Trump's coronavirus theories

President Donald Trump, who played down the threat of the coronavirus pandemic for months, said early Friday that he and his wife Melania had tested positive for Covid-19 and were going into isolation, potentially upending the race for the White House.

The number of coronavirus cases in the U.S. remains among the highest in the world, with Trump joining some seven million Americans who have tested positive, so far.

Here are several times that the president downplayed or endorsed theories dismissing the severity of the deadly pandemic.

Biden campaign says Trump team did not alert them about president's diagnosis

Neither the White House nor the Trump campaign has reached out to Joe Biden about Trump's diagnosis after the two appeared on the debate stage together on Tuesday, two Biden officials told NBC News.

Multiple Biden officials are expressing concern and frustration that Trump staffers and family members, many of whom took their maks off inside the debate hall, could have exposed so many people on Tuesday night.

Biden will get tested for Covid-19 on Friday, as will Jill Biden and campaign staff members who were at the debate on Tuesday.

Biden was scheduled to be in Michigan with multiple stops in Grand Rapids on Friday, including an event on the economy at a union facility and later a voter "mobilization” event with local Democrats. No decision has been made yet about whether he will still travel from Delaware.

Secretary Mnuchin "tested negative for Covid-19 this morning and will continue to be tested daily," the department's spokesperson Monica Crowley said in a tweet.

Mnuchin, who has frequently been seen wearing a mask, has been heavily involved in talks with lawmakers to try to pass the latest round of coronavirus relief.

Attorney General William Barr will get tested for Covid-19 out of an abundance of caution, according to a Justice Department spokesperson.

Pence, who tested negative, interacted with Trump earlier this week

The last known public contact between Pence and Trump appeared to be an outdoor Rose Garden event on Monday. But at a campaign event in Lititz, Pennsylvania on Tuesday ahead of the presidential debate, Pence told an indoor crowd of supporters that he had spoken with the president in the Oval Office earlier that day.

"It's gonna be a great night. I can tell you, I left the president earlier today in the Oval Office and he's ready," Pence said Tuesday to a large crowd of mostly maskless supporters.

Chris Christie says no masks during Trump debate prep

Former New Jersey Gov. Chris Christie, who helped Trump prepare for Tuesday's presidential debate, said that "no one" was wearing masks in the room during preparations. 

"No one was wearing masks in the room when we were prepping the president," he told ABC's "Good Morning America," adding that he "feels fine" and is not showing any signs of Covid-19. 

He said on Twitter later Friday morning that he was tested for the virus on Tuesday and again on Friday morning and is waiting on his results.

Christie was one of many people who were in close contact with the president in the days leading to his Covid-19 diagnosis. Former New York City Mayor Rudy Giuliani, the president's personal lawyer, also assisted with debate prep.
