During the banquet, Baldwin posed as "Professor of Advanced Trumpology and Abnormal Psychology" at the now-obsolete Trump University and made fun of "guest lecturers" — Environmental Protection Agency head Scott Pruitt and Attorney General Jeff Sessions.
Baldwin also channeled Trump to apologize for referring to Sen. Elizabeth Warren (D-MA) as "Pocahontas" during an event honoring Native American veterans at the White House on Monday.
And of course, Baldwin did his Emmy-award winning impression of Trump, pledging to "make Iowa great again."
The comedian dropped the Trump impression and took on a more serious tone when he implored Hillary Clinton and Bernie Sanders, 2016 Democratic Party primary rivals, to unite for the sake of the Democratic Party.
"I am ready to fight," Baldwin told the 2,000 guests. "We've got party-building to do on a scale we've never known." He promised the audience he is "ready to fight to help the Democrats win."
"Let's make America America again," Baldwin implored during his speech, spinning Trump's campaign pledge to "Make America Great Again."
One step toward that? Let's "send Trump to a retirement home in Moscow where he belongs," the actor urged.
Earlier this month, Baldwin told an audience at his alma mater, George Washington University in Washington, DC, that he thinks he would make a good president.
"Would I think I'd be a good president? Yeah, I think I'd be a good president. To run for office is something that I want to do [but that] doesn't seem to be practical with my lifestyle and my children."
Baldwin, who studied political science while at GWU, also said that he's uncertain whether America would vote another celebrity into the Oval Office after Trump.
"I'm not quite sure that Trump has left it open for nontraditional candidates," he said. "The pendulum may swing the other way, and people are going to want people with real, bona fide credentials."
