"While Vice President Pence is considered a close contact with Mr. Short, in consultation with the White House Medical Unit, the Vice President will maintain his schedule in accordance with the CDC guidelines for essential personnel," he said.
Additionally, a source familiar with the matter told NBC News that Pence's senior political adviser, Marty Obst, also tested positive.
Obst was at the debate in Salt Lake City with Pence Oct. 7, posing maskless with him and others after the event.
Obst is not a government employee. Pence's office has not yet responded to requests for comment.
The vice president wore a mask Saturday while traveling on Air Force Two for his campaign events in Lakeland and Tallahassee, Florida, and took it off for his remarks.
Over the last several weeks, Pence has only on occasion worn a face covering, including Friday while early voting indoors.
At the beginning of October, President Donald Trump announced he had the virus and, after being treated at Walter Reed Medical Center, said he had fully recovered days later
