(Bloomberg) -- President Joe Biden and first lady Jill Biden aren’t considered close-contact exposures to Homeland Security Secretary Alejandro Mayorkas, who tested positive for Covid-19 three days after attending an outdoor event with them.

Biden, who received his booster shot three weeks ago, isn’t considered at risk because his most recent encounter was more than 48 hours before his positive test and occurred outdoors, the White House said.

Mayorkas tested positive Tuesday morning as part of routine testing before a planned trip, according to his department. He is fully vaccinated, experiencing only mild congestion and will isolate and work from home. 

The Bidens and Mayorkas both attended the National Peace Officers’ Memorial Service outside the Capitol building on Saturday. The Centers of Disease Control and Prevention doesn’t recommend quarantine for vaccinated people who aren’t deemed close contacts.
