Meadows told everyone after the election that he was infected with coronavirus, but it is not clear whether he first tested positive, according to sources. He traveled with President Donald Trump on Sunday and Monday.
He was also present at the White House election party on Tuesday and is in close contact with members of the presidential family.
White House officials are now wary, as Meadows has been around other employees while there is a possibility of infection, an aide told CNN.
This is a violation story and will be updated.
