More Democrats tested positive for COVID-19 Friday after Speaker of the House Nancy Pelosi confirmed her diagnosis just hours after attending a packed signing ceremony at the White House.

Pelosi was seen mingling with President Biden, Senator Chuck Schumer, Barack Obama, and other prominent politicians.

“The Speaker is fully vaccinated and boosted, and is thankful for the robust protection the vaccine has provided,” her spokesperson said.

Pelosi will “quarantine consistent with CDC guidance, and encourages everyone to get vaccinated, boosted and test regularly,” he added.

Senators Raphael Warnock and Susan Collins have also tested positive for the contagion.
