Washington (CNN) Vice President Mike Pence on Sunday described his novel coronavirus test as a "kind of invasive" and a "not comfortable" experience.

Pence and second lady Karen Pence both tested negative for the virus Saturday afternoon after a staff member of his office had tested positive.

"The test was quick, but it goes a fair amount to the sinuses and it is not comfortable," Pence said at a White House press briefing. "That is probably a good opportunity to say again to any American looking on, if you do not have symptoms you do not need a test."

Pence told reporters Saturday that his staffer who tested positive for coronavirus is "doing well," had "mild" cold-like symptoms for a day-and-a-half, and has not been at the White House since Monday.

Describing the test process as "kind of a pinch," Pence said Sunday the test "was kind of invasive, but we were grateful for the support."
