More than a dozen other congressional representatives have self-quarantined since coming into contact with coronavirus-infected people.

They include Sen. Ted Cruz, who is self-quarantined, and Reps. Matt Gaetz of Florida and Doug Collins of Georgia, who are also isolated after coming into contact with the virus at the conservative CPAC conference last week.

On Sunday, U.S. Sen. Rand Paul announced he has tested positive for COVID-19, becoming the first senator to do so.

U.S. Sen. Lindsey Graham also self-quarantined after meeting with two people who later tested positive. Reports say he has since tested negative for the virus. House Minority Whip Steve Scalise is also in self-quarantine after meeting with Diaz-Balart.

U.S. Sen. Amy Klobuchar’s husband also has tested positive for the coronavirus, the former presidential candidate said Monday.
