"Today, Marc Short, Chief of Staff to the Vice President, tested positive for COVID-19, began quarantine and assisting in the contact tracing process," Pence's press secretary Devin O'Malley said in a statement. "Vice President Pence and Mrs. Pence both tested negative for COVID-19 today, and remain in good health."
The statement continued, "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."
Earlier Saturday, a source familiar with the matter told CNN that Marty Obst, a senior adviser to Pence who is not a government employee, tested positive for coronavirus earlier this week.
On Saturday, Pence traveled to Florida for campaign rallies in Lakeland and Tallahassee. The vice president walked across the tarmac from Marine Two in a mask and boarded Air Force Two about an hour behind schedule. Pence rarely wears a mask upon boarding and did not wave at the top of the stairs before boarding Saturday as he typically does.
Pence emerged maskless from Air Force Two in Florida, running down the steps and jogging across the tarmac, fist pumping as he approached the podium. The vice president's office released the statement moments after he landed back at Andrews Air Force Base.
The news that a close aide to Pence has contracted coronavirus comes just 10 days before Election Day amid a blitz of campaign stops for Pence across the country in the past week, including trips to Indiana, Ohio, Pennsylvania and New Hampshire.
Short has been seen on the campaign trail actively eschewing the use of masks for months, including earlier this week traveling aboard Air Force Two. Neither Pence nor Short wore a mask on Pence's trip on Thursday and Friday.
As chief of staff to Pence, who leads the White House coronavirus task force, Short has been a key aide involved with the US coronavirus response. He has been reported to have advocated for an economy-first approach to the pandemic.
The US Centers for Disease Control and Prevention has issued guidance that says people should stay home for 14 days after having contact with a person who has Covid-19.
Despite Pence being in close contact with Short as recently as Friday, the vice president plans to continue campaigning. Late Saturday, the vice president's office released his schedule for Sunday, which includes more travel and remarks at a campaign rally in North Carolina.
Short's diagnosis comes weeks after President Donald Trump, first lady Melania Trump and several aides and members of White House staff tested positive. Pence, joined by Short, continued an active campaign schedule and did not quarantine, with his physician saying in a statement at the time that he did not need to do so because he was not in close contact with Trump or other individuals who tested positive.
Another Pence aide, communications director Katie Miller, previously tested positive for coronavirus in May.
