President-elect Joe Biden says he already knows what he's going to ask Americans to do on his first day in office – 100 days to mask.

"I'm going to ask the public for 100 days to mask,” says Biden. “Just 100 days to mask, not forever, 100 days, and I think we'll see a significant reduction. If that occurs with vaccinations and masking, to drive down the numbers considerably, considerably."

The president-elect also says he plans to keep Dr. Anthony Fauci in his current position, leading the coronavirus task force.

Fauci has served as the director of the National Institute of Allergy and Infectious Diseases since 1984.
