U.S. Sen. Rand Paul has tested positive for the novel coronavirus, his office posted on Twitter.

“He is feeling fine and is in quarantine. He is asymptomatic and was tested out of an abundance of caution due to his extensive travel and events. He was not aware of any direct contact with any infected person,” according to the statement.

The Kentucky Republican is the first U.S. senator to test positive for COVID-19, the disease caused by the novel coronavirus.

Paul, 57, an ophthalmologist, was among the many high-profile attendees at a recent fundraiser on March 7. Others who attended the The Speed Art Museum’s “Speed Ball” fundraiser gala– who also tested positive– include philanthropist Christy Brown, Louisville first lady Alexandra Gerassimides and Kentucky Author Forum leader Mary Moss Greenebaum.

He expects to be back in the Senate after his quarantine period ends and will continue to work for the people of Kentucky at this difficult time. Ten days ago, our D.C. office began operating remotely, hence virtually no staff has had contact with Senator Rand Paul.

We want to be clear, Senator Paul left the Senate IMMEDIATELY upon learning of his diagnosis. He had zero contact with anyone & went into quarantine. Insinuations such as those below that he went to the gym after learning of his results are just completely false & irresponsible! https://t.co/yqfxydsXBG
