Marc Short, the chief of staff to Vice President Pence, tested positive for the coronavirus on Saturday, making him the closest aide to Pence and the latest senior White House official to contract the virus.
The confirmation comes as Pence — who tested negative on Saturday — crisscrosses the U.S. for rallies in swing states in the remaining days of the campaign as he and President Trump fight to win reelection.
The White House says Pence will continue to campaign.
