Vice President Mike Pence has several aidwes who have tested positive for COVID-19 since Saturday.
Chief of Staff to the VP, Marc Short, is now quarantining after testing positive for COVID-19 Saturday.
The VP plans to maintain an aggressive campaign schedule this week despite his exposure to a top aide.
Pence and his wife have tested negative and are in good health, according the office press staff.
The Vice President is continuing his travel schedule "in consultation with the White House Medical Unit" and "in accordance with the CDC guidelines for essential personnel." Those guidelines require that essential workers exposed to someone with the coronavirus closely monitor for symptoms and wear a mask whenever around other people.
Short's diagnosis comes weeks after the coronavirus spread through the White House, infecting President Donald Trump, the first lady, and two dozen other aides, staffers and allies.
