U.S. Vice President Joe Biden said he decided not to make a 2016 run for the White House after concluding he couldn't, so late in the game, put together a campaign that would derail Democratic front-runner Hillary Rodham Clinton.

"Couldn't win," Biden said in an interview due to air Sunday on CBS News' "60 Minutes," when asked why he opted not to make a third bid for the Democratic nomination. "If I thought we could've put together the campaign that our supporters deserve and our contributors deserved, I would've gone ahead and done it," Biden said in a transcript provided by the network.

Sunday's interview was the first for Biden, 72, since announcing in the White House Rose Garden on Oct. 21 that the process of grieving the death of his son, Beau, had closed the window on any chance for a run. That ended months of speculation and cleared the path for Clinton to win the nomination she lost to Barack Obama in 2008.
