Mike Pence’s chief of staff, Marc Short, has tested positive for coronavirus infection this week, bringing the pandemic into the vice president’s inner circle.

Earlier Saturday, Bloomberg News reported that one of Pence’s closest political advisers, Marty Obst, had also been infected by the virus, adding further to the cases in and around the White House.

Short is Pence’s top aide, a constant presence in his company who frequently acts as a public spokesman for the vice president. Pence, who delivered a campaign speech in Tallahassee, Florida, on Saturday evening, has not reported a positive test.
