Republican Sens. Mitt Romney and Mike Lee on Sunday said they were going into self-quarantine after being exposed to Sen. Rand Paul, who tested positive for the coronavirus.

Both Utah lawmakers said they had been advised by doctors to isolate because of the amount of time they spent in proximity to Paul, of Kentucky, who announced his diagnosis on Sunday.

Romney’s office added that the senator “has no symptoms but will be tested.”

Paul was seen at a GOP senators’ lunch on Friday and swimming in the Senate gym pool on Sunday morning. He is the first known senator to test positive for COVID-19.

Romney and Lee joined colleagues Cory Gardner (R-Colo.) and Rick Scott (R-Fla.), who were already self-quarantined for exposure unrelated to Paul.

Asked about his rival, Romney, going into quarantine, President Trump said: “Romney’s in isolation? Gee, that’s too bad.” Trump said he was not being sarcastic.
