White House chief of staff, Mark Meadows, who appeared frequently without a mask at public events, has been diagnosed with COVID-19, a source familiar with the situation that was told to Reuters on Friday.
It wasn’t immediately clear when or how he was infected.
Another top campaign helper, Nick Trainer, has also tested positive for the virus, according to the source.
Meadows, Trump’s top advisor and former North Carolina lawmaker, was a regular companion of US President Donald Trump on the last frenzied days of the campaign events leading up to Tuesday’s presidential election.
Meadows, who attended an election night party at the White House attended by dozen of Trump loyalists, is the youngest official in Trump’s close circle to contract COVID-19, which killed more than 236,000 Americans.
Trump has regularly downplayed the severity of the virus, which has risen sharply in recent weeks and will continue into the winter. He has contradicted public statements by top health experts, even after an outbreak hit the White House in October.
The president was briefly hospitalized at the time he was infected with the virus. His wife and son Barron also tested positive for the coronavirus in October.
His national security advisor, Robert O’Brien, was also infected with the virus. Another friend of Trump’s, former Republican presidential candidate Herman Cain, died of the coronavirus in July after attending one of Trump’s rallies.
