Homeland Security Secretary Alejandro Mayorkas tested positive on October 19 for COVID-19 and is isolating at home, the agency said.
The Secretary has been fully vaccinated and is experiencing only “mild congestion”, DHS said in a statement.
The agency said he will work from home under the protocols recommended by the U.S. Centres for Disease and Prevention.
DHS said contract tracing is being done to check for possible exposure among others.
Mr. Mayorkas was with President Joe Biden on Saturday at the annual National Peace Officers’ Memorial Service at the Capitol, standing on the podium between first lady Jill Biden and FBI Director Christopher Wray.
