WASHINGTON (BLOOMBERG) - US President Donald Trump's chief of staff Mark Meadows, who was diagnosed with the coronavirus on Nov 5, was at the White House on Monday (Nov 16), according to people familiar with the matter.

The people, who asked not to be named as the matter isn't public, said Mr Meadows had fulfilled the requirement of the White House Medical Unit of testing negative for the virus two days in a row.

The chief of staff, who seldom wore a mask throughout the pandemic, was one of many people in the president's circle who have contracted the virus.

His spokesman, Mr Ben Williamson, said Mr Meadows first tested positive on Nov 5.

His infection was not widely known among the president's staff until Friday, Nov 6.

On Nov 3, election night, Mr Meadows spent time at the White House residence with Mr Trump's family, including all of his adult children, according to people familiar with the matter.

He helped persuade Mr Trump to deliver brief remarks to the country at 2.30am from the White House East Room.

Mr Meadows attended the address, in which the president claimed he had won the election before races had been called in key battleground states where votes were still being counted.

Among the people associated with Trump who have also tested positive for the virus are longtime adviser Corey Lewandowski and Republican lobbyist Jeff Miller.

They both attended the election night party at the White House, but it was unclear if they contracted the virus there.
