Pence traveled to Iowa on Friday after Miller’s positive test, a trip that was delayed for more than hour so that six members of the vice president’s staff who’d been in contact with Miller could disembark from Air Force Two.

Iowa Governor Kim Reynolds, who visited the White House on Wednesday and spent time near Miller, is considering self-isolating, according to two people familiar with the matter.

The state’s health director, Caitlin Pedati, accompanied Reynolds on the trip and is planning to self-isolate, one of the people said.

Reynolds and Pence were in each other’s company for extended periods during his Iowa trip, practicing social distancing. Neither official, though, wore a mask at meetings with state faith leaders and food industry executives.
