What the Virus's Timeline Could Mean for Trump

President Trump and Melania Trump's positive coronavirus tests have kicked off a flurry of testing among the political elite—followed by a midday sigh of relief from Democrats following news that Joe Biden tested negative. The New York Times has confirmation by way of his campaign. Meanwhile, one other positive case was apparently confirmed well before the Trumps': that of RNC Chair Ronna McDaniel. CNN has this statement: "After a member of her family tested positive for COVID-19, the Chairwoman was tested for the virus. On Wednesday afternoon, she got confirmation she was COVID-19 positive. She has been at her home in Michigan since last Saturday." Mike Pence and his wife have tested negative, as has Trump's youngest son, Barron. "All precautions are being taken to ensure he's kept safe and healthy," Melania Trump spokeswoman Stephanie Grisham told Fox News. More:

• Fox News also reported by way of a source that Ivanka Trump and Jared Kushner have tested negative.
• Joe Biden isn't the only other debate participant to seek a test following Trump's news. Moderator Chris Wallace said on Fox & Friends Friday, "You can bet ... I'm going to have to get a test." Politico quotes the 72-year-old as saying: "Although I think I was far enough away, you know, we all take that question: 'Were you exposed to somebody who has tested positive for COVID?' The answer is yes."

• Chris Christie also plans to get tested. Politico reports he spent time at the White House "off and on" between Saturday afternoon and Tuesday to help Trump prepare for the debate. He was tested daily, but he said he hadn't been tested since Tuesday morning.
• As for what potentially looms for Trump, NBC News talks to a number of doctors who say it would be useful to know exactly when Trump contracted the virus. That's because the early stage of the infection—say, the first three to five days—is often marked by little to no symptoms. Serious complications would generally appear during "days four through eight, but [it] can be later as well," per a Boston doctor who's been working with COVID-19 patients. Another says he's "had some patients get critically ill more than two to three weeks after the initial infection."
• NBC News adds it's likely Trump's oxygen levels will be closely watched using a pulse oximeter, as they can plunge even in cases where people don't have severe symptoms.
• Meanwhile, New Jersey Gov. Phil Murphy is calling for anyone who was at Trump's Thursday fundraiser in his state to get tested. NJ.com reports the event was held at his Bedminster golf club, and a source tells the New York Times Trump had contact with roughly 100 people.
• Sen. Mike Lee of Utah on Friday also revealed he'd tested positive after experiencing allergylike symptoms. He tweeted, "Unlike the test I took just a few days ago while visiting the White House, yesterday's test came back positive. On advice of the Senate attending physician, I will remain isolated for the next 10 days."
