Reps. Matt Gaetz (R-Fla.) and Mark Meadows (R-N.C.), the latter of whom Trump named last week as the next White House chief of staff, both said in statements that the tests showed no infection after exposure to a coronavirus carrier at the annual Conservative Political Action Conference last month in suburban Washington.

The two lawmakers also said they were exhibiting no symptoms of respiratory illness, raising questions of why they were tested at all.

The Centers for Disease Control and Prevention recommends that health-care providers prioritize tests for hospitalized patients who are exhibiting coronavirus symptoms, elderly and medically fragile individuals, along with others who have shown signs of illness after contact with a known or suspected coronavirus patient.

Gaetz, 37, and Meadows, 60, are not known to belong to any groups at high risk for infection.
