President Joe Biden came into close contact on Air Force One with a staff member who tested positive for COVID-19, the White House announced Monday.

White House press secretary Jen Psaki said the 79-year-old Biden, who is fully vaccinated and boosted, has so far tested negative after coming into contact with the staffer on Friday.

"On Monday morning, a mid-level staff member, who does not regularly have contact with the President, received a positive result for a COVID-19 test," Psaki said. "Three days earlier, on Friday, that staff member had spent approximately 30 minutes in proximity to the President on Air Force One, on the way from Orange, South Carolina to Philadelphia, Pennsylvania."

The staff member is fully vaccinated and boosted, Psaki said, adding that this person "tested negative prior to boarding Air Force One, as is required for everyone traveling with the President. This staff member did not begin to experience symptoms until Sunday, and was tested on Monday."


As for Biden, Psaki said, he is tested on a regular basis, and as part of that process, he "received an antigen test Sunday, and tested negative. This morning, after being notified of the staffer’s positive test, the President received a PCR test and tested negative. He will be tested again on Wednesday."

"As CDC guidance does not require fully vaccinated people to quarantine after an exposure, the President will continue with his daily schedule," she added.

In her statement, Psaki stressed that the White House is making good on a promise to keep the public informed.

"As we stated last summer, we believe it is in the public’s interest to know if any of the four principals (President, Vice President, First Lady, and Second Gentleman) are considered to have been in close contact with a White House official who subsequently tests positive for COVID-19 shortly after that contact," she said.

The criteria for what is considered “close contact” is determined by the White House Medical Unit, in line with guidance from the Centers for Disease Control and Prevention, Psaki said.


The announcement comes roughly a day after a pair of U.S. senators and one House member announced they tested positive for COVID-19. Sens. Elizabeth Warren and Cory Booker, both Democrats, announced their diagnoses on Twitter, followed by Rep. Jason Crow, a Democrat from Colorado. All three said they are fully vaccinated and boosted and have mild cases.

The positive tests come as the omicron variant of COVID-19 quickly spreads across the United States and the rest of the world, feeding a winter surge in cases and accompanying wave of new restrictions meant to stop the spread.

The White House announced over the weekend that Biden would deliver a speech Tuesday on the administration's plans to combat COVID-19 this winter. That speech is scheduled for 2:30 p.m.
