WASHINGTON – House Speaker Nancy Pelosi, GOP Sen. Susan Collins of Maine and President Joe Biden’s sister became the latest Washington figures to test positive for COVID-19, announcements that came Thursday after two cabinet officials and others tested positive the day before.

Pelosi, who is asymptomatic, tested positive on Thursday. She will quarantine, her spokesman announced.

“The speaker is fully vaccinated and boosted, and is thankful for the robust protection the vaccine has provided,” said spokesman Drew Hammill. 

Pelosi attended crowded events at the White House Tuesday and Wednesday at which Biden spoke. 

The White House said Biden’s interactions with Pelosi do not meet the Centers for Disease Control and Prevention’s definition of being in close contact. 

Late Thursday evening another White House official said they too had tested positive for COVID-19.

Michael LaRosa, press secretary for the First Lady Jill Biden, tested positive for the virus, LaRosa confirmed to USA TODAY.

Collins tests positive after Supreme Court vote

Collins, one of three Republicans who broke from her party to vote to confirm Ketanji Brown Jackson to the Supreme Court, tested positive late Thursday afternoon. 

Her office said the senator is experiencing mild symptoms and will isolate and work remotely following the diagnosis. 

Collins’ positive test came just hours after she voted for Jackson’s historic nomination. Last week, Senate Judiciary Chair Sen. Dick Durbin, D-Ill., warned reporters that the confirmation wasn’t a done deal until after the vote, because something like a senator testing positive for COVID and being unable to vote could disrupt the process. 

The senator attended the annual Gridiron Dinner on Saturday, as did two cabinet members who have since tested positive. LaRossa also attended the dinner, which attracts a wide swath of government officials and journalists. Some lawmakers and reporters who were at the dinner have also tested positive.

Democratic Sen. Raphael Warnock of Georgia announced Thursday evening that he too has the virus, tweeting “Late this afternoon after a routine test, I tested positive for COVID-19. I’m so thankful to be both vaccinated & boosted, and at the advice of the Attending Physician I plan to isolate.”
