Bernie Sanders pledges to stay in race

Santa Monica, California (CNN)Bernie Sanders isn’t leaving the stage yet.

Sanders channeled his supporters’ defiance when he took the stage shortly before 11 p.m. PT and told them what they wanted to hear: he’s not ready to concede the Democratic nomination to Hillary Clinton, who secured the delegates she needs on Monday.

“Let me thank you all for being part of a political revolution,” Sanders said as he took the stage. “All of you know that when we began this campaign over a year ago we were considered to be a fringe campaign. Over the last year I think that has changed a little bit.”

“We understand our mission is more than just beating Donald Trump, it is transforming our country,” he said.
