House Speaker Nancy Pelosi tests positive for COVID-19

House Speaker Nancy Pelosi has tested positive for COVID-19 and is in quarantine, according to an announcement from her office on Thursday morning.

The speaker's deputy chief of staff, Drew Hammill, announced Pelosi's positive test on Twitter, writing, "After testing negative this week, Speaker Pelosi received a positive test result for COVID-19 and is currently asymptomatic. The Speaker is fully vaccinated and boosted."

Pelosi was at the White House on Wednesday with President Joe Biden.

The 82-year-old California Democrat is the latest Washington politico to test positive in recent days.

Earlier this week, Commerce Secretary Gina Raimondo and an aide to Vice President Kamala Harris also tested positive. 

Raimondo attended the Gridiron Club and Foundation dinner this past weekend with hundreds of other D.C. insiders. There there is now speculation that the traditional gathering for D.C. insiders could have been a so-called "super spreader" event.
