Sen. Lindsey Graham said Thursday he will self-quarantine after visiting President Trump at Mar-a-Lago last weekend along with a Brazilian official who tested positive for coronavirus, officials said.

“Senator Graham was at Mar-a-Lago last weekend,” the South Carolina Republican’s office said in a statement.

“He has no recollection of direct contact with the President of Brazil, who is awaiting results of a coronavirus test, or his spokesman who tested positive,” the statement said, referring to President Jair Bolsonaro and Fabio Wajngarten, the spokesman.

“This is a precautionary measure. He will continue to work from home.”

Graham, a staunch Trump ally and frequent guest at his Florida resort, joins a list of lawmakers who have self-quarantined, including Reps. Matt Gaetz of Florida, Doug Collins of Georgia and Mark Meadows of North Carolina. Gaetz later tested negative for the virus.

The commander-in-chief was photographed with the press aide and shook hands with Bolsonaro, but said he felt fine and that White House physicians told him he did not need to be tested.
