医生说，随着唐纳德·特朗普(Donald Trump)总统对抗冠状病毒感染，他的病情正在继续改善，他最早可能在周一离开沃尔特·里德医疗中心——尽管有细节显示，据称总统最初对新冠肺炎的检测结果比他承认的要早。
医生还报告说，特朗普在表现出冠状病毒症状的过程中，早些时候经历了两次血氧饱和度的“短暂下降”。
然而，总统周日晚上感觉很好，短暂地离开沃尔特·里德，去了一个惊喜的驾车路过，在医院外面向支持者挥手。
与此同时，在与总统有关的一周事件后，政府最高层有多少人暴露于病毒仍有许多问题，在白宫和其他地方，社交距离和戴口罩都很宽松。

消息人士称，截至周日晚上，特朗普获释的时间表仍未敲定。医生周日早些时候表示，特朗普最早可能在周一出院。
白宫表示，对特朗普的乘坐采取了“适当的预防措施”
白宫表示，特朗普总统周日晚上在沃尔特·里德医院外的驾车路过是“安全的”，即使他在对抗冠状病毒。
特朗普发言人贾德·迪尔(Judd Deere)表示，在短暂的旅程中采取了“适当的预防措施”，除了使用个人防护装备之外，几乎没有给出其他细节。
迪尔在一份声明中说:“医疗小组认为此举是安全的。”。

2020年10月4日，在沃尔特·里德医疗中心外，唐纳德·特朗普总统的车队经过支持者时，他挥手致意。
然而，传染病专家告诉美国广播公司新闻，总统很可能仍然具有传染性。
范德比尔特大学预防医学教授威廉·沙夫纳博士说，“你必须在一定的天数内没有症状，并且从你生病开始的10天——或者你的测试呈阳性的日期。”
“他做了一些没人会推荐的事情，”他告诉美国广播公司新闻，说他可能把和他一起骑车的特勤局成员置于危险之中。
“这似乎不是一次必要的旅行，”沙夫纳说。
拜登测试呈阴性
副总统乔·拜登的竞选团队表示，他今天接受了聚合酶链反应检测，结果呈阴性。
该活动不会提供更多关于测试的细节。
巴尔在自我隔离，获得第三次阴性测试结果
司法部发言人克里·库佩克告诉记者，司法部长比尔·巴尔正在家中进行自我隔离，但迄今为止病毒检测呈阴性。
这位女发言人不愿提供巴尔自我隔离的更多细节。
这是自上周二辩论以来，他第三次对新冠肺炎的检测呈阴性。巴尔出席了9月26日的事件在白宫，特朗普总统宣布艾米·科尼·巴雷特法官为他的最高法院大法官提名人。
上周感染病毒的几名特朗普政府官员，包括凯利恩·康威和前州长克里斯·克里斯蒂，出席了活动，在户外仪式上没有戴口罩。
巴尔被拍到在活动期间不戴口罩与康威交谈。
Trump COVID-19 live updates: President did not disclose 1st positive test, sources say
President Donald Trump's condition is continuing to improve as he fights a coronavirus infection, doctors say, and he may be able to leave Walter Reed Medical Center as early as Monday -- even as details emerge that the president allegedly initially tested positive for COVID-19 earlier than he acknowledged.
Doctors also reported that Trump, over the course of exhibiting coronavirus symptoms, had earlier experienced two episodes of "transient drops" in his oxygen saturation.
Yet the president was feeling well enough Sunday evening to briefly leave Walter Reed for a surprise drive-by, waving to supporters outside the hospital.
Meanwhile, numerous questions remain about how many people at the highest levels of government had been exposed to the virus after a week of events involving the president where social distancing and mask-wearing were lax in the White House and elsewhere.
President wants to leave hospital as soon as possible
Sources tell ABC News that President Trump was in good spirits Sunday, and was insisting that he wants to leave Walter Reed Medical Center as soon as possible.
This handout photo released by the White House shows US President Donald Trump and his Chief of Staff (not pictured) participating in a phone call with the US Vice President, Secretary of State and Chairman of the Joint Chiefs of Staff on October 4, 2020, at Walter Reed National Military Medical Center in Bethesda, Maryland.
Aides are pushing Trump to relax, sources say.
A timetable on Trump's release was still not finalized as of Sunday night, sources said. Doctors said earlier Sunday that Trump could leave the hospital as early as Monday.
White House says 'appropriate precautions' taken for Trump's ride
The White House says President Trump's drive-by outside Walter Reed hospital Sunday evening was "safe to do," even as he fights the coronavirus.
Trump spokesman Judd Deere said "appropriate precautions" were taken for the short ride, giving little details other than PPE was used.
"The movement was cleared by the medical team as safe to do," Deere said in a statement.
In this still image from video footage, President Donald Trump is seen waving as his motorcade drives past supporters outside Walter Reed Medical Center, Oct. 4, 2020.
However, infectious disease experts tell ABC News that the president is likely still infectious.
Dr. William Schaffner, a professor of preventive medicine at Vanderbilt University, said, "You have to have been a certain number of days symptom-free, and 10 days from the onset of your illness -- or the date of positivity of your test."
"He's done something that no one would recommend," he told ABC News, saying that he may have put the Secret Service members who rode with him at risk.
"This did not appear to be an essential trip," Schaffner said.
Biden tests negative
Vice President Joe Biden's campaign said he underwent PCR testing today and the results came back negative.
The campaign wouldn't provide more details about the test.
Barr is in self-quarantine, gets 3rd negative test result
Department of Justice spokeswoman Kerri Kupec told reporters that Attorney General Bill Barr is self-quarantining at home, but has so far tested negative for the virus.
The spokeswoman would not provide more details about Barr’s self-quarantine.
This is the third time he has tested negative for COVID-19 since last Tuesday's debate. Barr attendedthe Sept. 26 eventat the White House where President Trump announced Judge Amy Coney Barrett as his Supreme Court Justice nominee.
Several Trump administration officials who contracted the virus last week, including Kellyanne Conway and former Gov. Chris Christie, attended the event and were not wearing masks during the outdoor ceremony.
Barr was photographed talking with Conway while not wearing a mask during the event.
