Ellison was one of the few Muslims to serve in the House before becoming Minnesota attorney general and was one of the chamber's most vocal progressives. He's likely one of the few Democrats with cache within the party who also has appeal to the pro-Palestinian protesters outside, making him a potent messenger for Harris on this issue.

The controversial conservative policy blueprint has become a flashpoint in the 2024 election.

As a result, Trump has tried to put space between his 2024 campaign and the project, despite some of his close advisers and former administration officials being involved in its creation.

"I know nothing about Project 2025," Trump has claimed on social media. "I have no idea who is behind it."

Democrats, however, are intent on tying the policy wishlist to Trump. Speakers this week have decried its proposals on everything from reproductive rights and health care to agency regulation.

Minnesota Attorney General Keith Ellison, now taking the stage, indicated to ABC News earlier Wednesday that he would address the Gaza crisis directly -- and protesters who have raised their voices at the DNC -- during his speech.

"I don't know how much disagreement there is. I think we all want to see the violence stop and civilians have safety and security, and to see Gaza restored. I think there's general agreement on that,” he said.

Colorado Gov. Jared Polis brought back the Project 2025 prop book and continued the theme of slamming its conservative policy proposals.

Polis, a self-proclaimed "Swiftie," cited one of the pop star's famous lyrics in denouncing the ideology.

"These Project 2025 people like Trump and Vance are not just weird, they're dangerous. They want to take us backwards. But we aren't going back. Like ever, ever, ever," he said to applause.
