Sen. Bernie Sanders, I-Vt., may have lost the Democratic presidential nomination to Hillary Clinton, but he's not giving up the fight. Sanders is scheduled to kick off Our Revolution, a nonprofit aimed at keeping up the enthusiasm for progressivism he generated during his campaign, Wednesday night.

Sanders will speak at 9 p.m. EDT from Washington, D.C. You can catch a live stream of the speech here or below:

Our Revolution grew out of the ashes of Sanders' campaign, which throughout the primary season gained a reputation for exciting young voters and fighting against political corruption. He started promoting the group not long after the Democratic National Convention ended last month.

"During our campaign we assembled a movement of millions of people ready to fight for the country we know we can become," the Hill reported Sanders wrote in a recent email to his backers. "Now it's time for all of us to get to work."

On Wednesday, Sanders is expected to outline his new initiative and support like-minded candidates down the ballot. He's already launched a donation page, which gives contributors the option to send the organization $27 — once the average gift to Sanders' presidential campaign.

"The goal here is to do what I think the Democratic establishment has not been very effective in doing," he told USA Today last month. "And that is at the grass-roots level, encourage people to get involved, give them the tools they need to win, help them financially."

That said, Our Revolution hasn't been without growing pains. NBC News reported that eight major players who came over from the campaign left the group's staff this past weekend. Politico wrote the staffers had issues with the campaign finances and Jeff Weaver, Sanders' former campaign manager, who was tapped to be the new organization's president.
