Senator Lindsey Graham has tested negative for the novel coronavirus, the Republican from South Carolina announced via tweet on Sunday.
“I’m very grateful and like everyone else will follow the best practices to stay negative,” Graham added.
However, some tweets in response questioned the ease with which he got tested, particularly as the U.S. grapples with being woefully behind and unprepared when it comes to testing.
As CNN notes, it is also unclear how he came to be tested when the Centers for Disease Control and Prevention recommends that only those showing symptoms be tested.
Graham had been under self-quarantine after potentially coming into contact with Brazilian President Jair Bolsonaro’s spokesperson, Fabio Wajngarten, who tested positive for the virus.
Despite the negative test, which was just a “precautionary measure,” according to the senator’s office, Graham will “continue to work from home.”
