The Louisiana Republican, who is a medical doctor, was tested for the virus after he was informed that he was in contact with an individual who tested positive.

“I am strictly following the direction of our medical experts and strongly encourage others to do the same,” Cassidy said in a statement.

According to his office, Cassidy will quarantine for 14 days per recommendations from the Centers for Disease Control, and is “notifying those with whom he may have come into contact.” His office didn’t say whether the senator, 62, has symptoms, and if so, the severity.
