Democratic Sens. Warren, Booker test positive for COVID-19 in breakthrough cases

Sen. Elizabeth Warren, D-Mass., and Sen. Cory Booker, D-N.J., both tested positive for COVID-19 on Sunday and are experiencing "mild" symptoms. The Democratic senators are the most recent public figures to test positive in breakthrough cases while the Omicron variant sweeps the nation.

"I regularly test for COVID & while I tested negative earlier this week, today I tested positive with a breakthrough case. Thankfully, I am only experiencing mild symptoms & am grateful for the protection provided against serious illness that comes from being vaccinated & boosted," Warren, a former Democratic presidential primary candidate, tweeted.

She added that "as cases increase across the country" others should also get vaccinated to "save lives."

Several hours after Warren announced her positive test, Booker tweeted he also tested positive for COVID-19. "My symptoms are relatively mild. I’m beyond grateful to have received two doses of vaccine and, more recently, a booster – I’m certain that without them I would be doing much worse," he wrote.

Booker, also a former Democratic presidential primary candidate, encouraged Twitter users get vaccinated as well.

Warren and Booker join other senators who have had breakthrough cases of COVID-19. Sens. Roger Wicker, R-Miss., Angus King, I-Maine, and John Hickenlooper, D-Colo., all tested positive in August despite being fully vaccinated.
