Bernie Sanders To Hillary Clinton: 'It's Silly To Keep Talking About 2016'

Sen. Bernie Sanders had a sharp response to his former Democratic primary rival Thursday night during his appearance on "The Late Show With Stephen Colbert." Prompted by Colbert to reply to a portion of Hillary Clinton's book, "What Happened," in which she wrote that Sanders' "attacks" had "lasting damage, making it harder to unify progressives," the senator from Vermont said the progressive movement is "stronger now than it has been in many, many years."

Sanders said that as a result of his campaign, millions of young people became engaged politically and voted for the first time. (For more national political news, sign up for the free White House Patch email newsletter.)

"But I understand," Sanders continued. "Secretary Clinton ran against the most unpopular candidate in the history of this country, and she lost, and she was upset by that, and I can understand that. But our job now really is not to go backwards, it's to go forwards. It is to kind of create the nation that we know we can become.

"We have enormous problems facing us, and I think it's a little bit silly to keep talking about 2016."

Colbert went on to ask the self-proclaimed Democratic socialist about Clinton's claims that he made "pony promises" to voters during his campaign. For Sanders' answer to that question and more, watch the full "Late Show" clip below.
