Bernie Sanders told MSNBC's Morning Joe that he will vote for Hillary Clinton, because "I'm gonna do everything I can to defeat Donald Trump."
Sanders says he'll stay in the race to push Clinton to the left.
But Sanders also dismissed the idea that he should withdraw from the Democratic race now that Clinton has secured the nomination.
"Why would I want to do that when I want to fight to make sure that we have the best platform that we possibly can, that we win the most delegates that we can?" he said.
And in a later interview on CBS, Sanders declined to formally endorse Clinton, although he indicated that he "hopes" to before the convention.
"I haven't heard her say the things that need to be said," he said.
