White House press secretary Jen Psaki said Sunday she has contracted COVID-19 and is experiencing mild symptoms.

Psaki, 42, said she was last in contact with President Joe Biden on Tuesday, when she met him in the White House, where they were more than 6 feet apart and wearing masks. Biden, who is tested frequently, last tested negative on Saturday, according to the White House.

Psaki did not accompany Biden on his trip abroad to Rome this weekend for the Group of 20 summit and Glasgow, Scotland, on Monday for a UN climate summit.

Psaki had planned to travel with the president but scrapped the trip just as he was set to depart for Europe after learning that members of her household had tested positive for COVID-19.

“Since then, I have quarantined and tested negative (via PCR) for COVID on Wednesday, Thursday, Friday, and Saturday,” Psaki said in a statement. “However, today, I tested positive for COVID.”
