A Republican National Committee spokesperson also confirmed Thursday that Richard Walters, the party organization’s chief of staff, had tested positive, as well. Walters did not attend the election night party.
And Lewandowski is the latest of several Trump campaign aides and administration officials who have recently tested positive in what appears to be a third White House coronavirus outbreak.
Roughly three dozen people, including the president, were infected in September and October following a White House ceremony celebrating Justice Amy Coney Barrett’s Supreme Court nomination.
Several top aides to Vice President Mike Pence also tested positive in a separate spate of infections last month, including his chief of staff Marc Short.
Lewandowski served as Trump’s campaign manager in the 2016 Republican presidential primary, and has long been a loyal ally to the president.
In June, Trump appointed Lewandowski and Bossie to serve on the Commission on Presidential Scholars, a Department of Education panel tasked with awarding special recognitions to high school seniors.
