He made the announcement during his two-hour speech on the final day of the Conservative Political Action Conference in National Harbor, Maryland. The White House has not yet released any further details on Trump’s forthcoming order, and the timeline for the action remains unclear.

President Donald Trump vowed Saturday to roll out an executive order to protect free speech on college campuses, threatening to revoke federal funding from those that don’t support it.

Just before he broke the news, Trump invited conservative activist Hayden Williams up to join him on the stage. Williams was shoved and punched in the face last month at the University of California, Berkeley while trying to recruit students to the school’s Turning Point USA chapter. He’s not a student there, and works for the Leadership Institute, another conservative organization.

For a few moments, Trump gave him the podium to speak.

“If these socialist progressives had their way, they would put our Constitution through the paper shredder in a heartbeat,” he said, rallying conservatives to keep “exposing these liberal abuses to the public.”

“If you keep defending us, we’ll keep defending you,” he told Trump.

Returning to the podium, the president then praised Williams, appearing to liken him to famed boxer Muhammad Ali.

“He took a hard punch in the face for all of us,” Trump said of Williams. “Remember that.”

Fox News anchor Jeanine Pirro later offered her kudos to the president in a speech of her own while clapping and declaring, “That’s right! Play hardball with the money, baby!”
