Biden says he'd lock down country if spread of coronavirus warranted it

Democratic presidential nominee Joe Biden said he would do "whatever it takes" to combat the spread of coronavirus within the country - including locking down the U.S. if deemed necessary.

"I would shut it down; I would listen to the scientists," Biden told ABC's David Muir in a joint interview with his running mate, Sen. Kamala Harris, to air Sunday. "We're going to do whatever it takes to save lives."

Biden's comments represent the strongest potential action the Democratic presidential nominee has proposed to stanch the spread of the virus that has killed at least 175,000 people across the U.S. as of Friday evening.
