Joe Biden pushed back on suggestions that the November election could be postponed amid the coronavirus pandemic, saying Sunday it's important that voting continues as it has during other crises in American history.

"We have to let the electoral process run. We ought to be able to preserve our health and our democracy at the same time," the 2020 Democratic front-runner said.

"You know, we voted in the middle of a civil war, we voted in the middle of World War I and II," the former vice president said on a conference call with Atlanta-area donors.
