Mr Meadows was at a White House party on election night and was seen without a mask.

He has frequently appeared at events without a face covering and accompanied the president in the final days of the campaign rallies.

Mr Meadows last appeared in public on Wednesday morning, again without a mask, as the president attempted to claim victory in the election.

The diagnosis was confirmed on Friday by two senior White House officials.

Another top campaign official, Nick Trainer, has also tested positive, a source told the Reuters news agency.
