"After testing negative consistently,including every day since Thursday,I tested positive for COVID-19 on Monday morning while experiencing no symptoms,"McEnany posted to Twitter.
"As an essential worker,I have worked diligently to provide needed information to the American People at this time,"she wrote."With my recent positive test,I will begin the quarantine process and will continue working on behalf of the American People remotely."
Two more members of the press team,Karoline Leavitt and Chad Gilmartin,who is McEnany's relative,also tested positive but learned about their diagnoses before McEnany,two people familiar with the diagnoses toldThe New York Times.
McEnany spoke briefly with reporters on Sunday evening,but said that no members of the White House press corps spent enough time around her to be considered close contacts.
She joins a growing list of infected Trump associates that includes first lady Melania Trump,at least two White House aides who travel with the President and three Republican senators.
McEnany was among several officials who attended a ceremony in the Rose Garden at the White House late last month when Trump introduced Judge Amy Coney Barrett as his nominee to the Supreme Court. That was a common event for many of those in the administration or Congress who later tested positive.
