President Biden coughed into his hand following a Monday speech in New Jersey and proceeded to use it to shake hands with members of the public, all while not wearing a mask.

The incident comes less than a week after Homeland Security Secretary Alejandro Mayorkas tested positive for COVID-19 just days following an event with the president.

Last Tuesday, a fully vaccinated Mayorkas tested positive for COVID-19 as part of routine pre-travel protocols.

Three days earlier, Mayorkas had attended the 40th Annual National Peace Officers’ Memorial Service at the U.S. Capitol alongside Biden, where they were photographed just feet apart without masks.

Earlier this month, the president and first lady stoked controversy when they were caught walking without a mask through Fiola Mare, a ritzy Italian seafood restaurant in Washington, D.C., where all individuals over age 2 are required to wear a mask indoors, regardless of vaccination status.
