"Yes, yes," 74-year-old Sanders told MSNBC in an interview when asked if he is going to vote for Clinton in November.
Sanders, who gave a tough fight to 68-year-old Clinton during primaries, has not yet announced a formal endorsement of his party's presumptive presidential nominee.
In his interview, Sanders said he would work to defeat Donald Trump, the Republican presidential presumptive candidate.
"I think the issue right here is I'm going to do everything I can to defeat Donald Trump. I think Trump in so many ways will be a disaster for this country, if he were to be elected president," Sanders said.
"So your vote will be a vote for Hillary Clinton or against Donald Trump?" he was asked.
"What I am trying to do right now is to make sure that the Democratic party becomes the party that represents working people, not Wall Street, that is prepared to have an agenda that speaks to the need of creating millions of jobs, raising the minimum wage to USD 15.00 an hour, dealing with climate change, dealing with pay equity. Those are the issues that we need to have not only in a platform, but we need Democratic leadership to be implemented," he said.
"I'm pretty good at arithmetic, and what I know is that Hillary Clinton has more pledged delegates than I do, and she has a lot more super-delegates than I do," Sanders said.
