Turns out he should have worn the mask he taunted Biden with during the debate.
The White House has issued a new schedule for Trump's activities on Friday that did not include his planned trip to Florida.
At one point, Trump mocked his opponent for his frequent wearing of masks, when questioned on his distrust of their efficiency.
Hicks, who serves as counselor to Trump and traveled with him to a rally Wednesday, tested positive Thursday, according to an administration official, who spoke on condition of anonymity to discuss private health information. He said she has been working without taking even a small break.
White House aides are tested for the virus regularly; some, like White House chief of staff Meadows, are tested daily.
US Space Force decides to fly on reused SpaceX Falcon 9
SpaceX plans to try again to launch its 13th cluster of Starlink communications satellites Monday from Florida. The launch was originally pencilled in for Friday, September 18, but poor weather scuppered the launch.
The latest development is likely to be a blow to Trump's campaign, which has relied on in-person rallies, despite being in the midst of a pandemic, to galvanize the president's base. "I felt no vulnerability whatsoever", he told reporters back in May.
The news was sure to rattle an already shaken nation still grappling with how to safely reopen the economy without driving virus transmission.
The president largely eschews wearing masks and has criticized others who do.
Barely two weeks ago, Trump had told the U.N. General Assembly that China, where the virus first emerged late previous year, should be held accountable for unleashing "this plague on the world".
"The President takes the health and safety of himself and everyone who works in support of him and the American people very seriously", he said. "And you get close to them - and things happen".
The American president testing positive for the highly contagious virus has become the biggest talking point on social media as thousands of people wished him a quick recovery. German Chancellor Angela Merkel self-isolated after a doctor who gave her a vaccination tested positive for the virus, and Canadian Prime Minister Justin Trudeau worked from home after his wife fell ill. Former Italian Prime Minister Silvio Berlusconi was hospitalized last month while fighting what he called a "hellish" case of COVID-19.
Her 2018 resignation came one day after she testified before the House Intelligence Committee in its investigation into Russian interference in the 2016 presidential election.
