Sen. Rand Paul hit back at critics who accused him of being irresponsible for not self-quarantining before his coronavirus test came back positive.

Paul, who said he had no symptoms, did not isolate himself from others until his test came back positive. He was at a luncheon on Friday with his Republican colleagues and was accused of using the Senate gym on Sunday morning. Republican senators in contact with Paul in recent days have since self-quarantined out of precaution.
