WASHINGTON -- White House spokeswoman Jen Psaki tested positive for COVID-19 on Tuesday, she said in a statement, adding that U.S. President Joe Biden had tested negative in a PCR test.

Psaki said she was tested in preparation for travel with Biden on Wednesday to Belgium and Poland, where the president will meet with U.S. allies over the Russia-Ukraine war. She said she is experiencing mild symptoms.

"I had two socially-distanced meetings with the President yesterday, and the President is not considered a close contact as defined by CDC guidance. I am sharing the news of my positive test today out of an abundance of transparency," Psaki said in a statement.

Psaki last tested positive for the coronavirus on Oct. 31. She said she will work from home and plan to return to the White House "at the conclusion of a five-day isolation period and a negative test."
