Congresswoman Barbara Lee tests positive for COVID-19

Representative Barbara Lee has tested positive for COVID-19, she tweeted Tuesday. The California congresswoman said she is fully vaccinated and received a booster dose and is experiencing "cold-like symptoms."

"I know it could have been much worse had I not been vaccinated," the 75-year-old Democrat wrote. "I'm so grateful for the miraculous work of vaccines & urge everyone to get vaccinated & boosted!"

The announcement comes as the nation sees a sharp increase in the number of COVID-19 cases, with Omicron now the most common strain in the U.S. On Tuesday, President Joe Biden announced a new plan to tackle the highly transmissible variant, including manufacturing 500 million at-home tests, opening more COVID-19 testing sites and sending troops to hospitals in need of staff.
