While Donald Trump is fixated on alleged voters fraud, his chief of staff Mark Meadows is diagnosed with Coronavirus.
Two sources at the White House confirmed on Friday that Mr Meadows had tested positive for the virus.
The US has recorded more than 235,000 fatalities to COVID-19 just this year.
Mr Meadows was last seen without a mask publicly on Wednesday morning when Mr Trump declared the self victory.
When the President was diagnosed with coronavirus more than a month ago, Mr Meadows was one of the close aides around him regularly, however, was tested daily and maintained his work schedule.
The development marks the latest uprise of the virus in the West Wing of the White House, shortly after Marc Short, the Vice President’s Chief of Staff and other aides tested positive for the virus.
In early October, the first lady Melania Trump and at least 12 others tested positive for the virus.
This was after Trump held a gathering including the ceremony announcing the nomination of now-Justice Amy Coney Barret to the Supreme Court and the attendees all hug, shake and refused to wear masks.
Trump has continued to tell his many followers that the pandemic is coming to an end.
As a result of the election, confirmed cases in the US have increased by 50% in the past two weeks.
