Lewandowski is the latest person in Trump's orbit to contract the virus since Election Day, though it was not immediately clear when he became infected.

Lewandowski was at a White House party on the night of the election, and he has mostly been in Pennsylvania in recent days as part of an effort to challenge the outcome there.

Lewandowski served as the president's campaign manager for part of his 2016 White House bid, and he has remained an adviser and supporter during Trump's time in the White House. He joined the 2020 campaign as a senior adviser in recent months.

He previously had a brush with the virus after attending a White House event in late September to nominate Amy Coney BarrettAmy Coney BarrettDemocratic Rep.

The White House election night party has emerged as the latest super-spreader event inside the building, though.
