On Sunday, Senate Democrats' claims that his presence after possible exposure to the coronavirus would be a "violation of common decency."

Driving the news: Five of Pence's aides were recently diagnosed with COVID-19, including his chief of staff, who is currently quarantining. Pence has continued his campaign travel despite his possible exposure, which goes against CDC guidelines.
