Biden in 2020? With a smile, he says he's not ruling it out

[...] uh, what the hell, man, the departing vice president told reporters Monday with only a slight smile on his face.

The vice president decided to not seek the White House in 2015 and instead backed this year's eventual Democratic presidential nominee, Hillary Clinton.

A senator for 36 years before becoming vice president, Biden was emotional after Senate Majority Leader Mitch McConnell, R-Ky., a friend, got the Senate to name a portion of the measure after Biden's son, Beau, who died of cancer last year.
