First lady Jill Biden tested positive for COVID-19 and is experiencing "mild symptoms," the White House stated.
President Joe Biden recovered from COVID earlier this month.
The first lady's communications director Elizabeth Alexander on Tuesday said that Jill Biden tested positive after developing "cold-like symptoms" Monday evening.
She tested negative twice on Monday but a PCR test came back positive, Alexander said.
The first lady, who is double vaccinated and twice boosted, plans on isolating for at least five days in a private home in South Carolina.
