The stars of the hit sitcom "Will & Grace" reunited for Hillary Clinton.
McCormack's Will Truman and Messing's Grace Adler are supporters of Clinton, though Karen Walker, played by Mullally, is firmly in the Trump camp.
Hayes' Jack McFarland is an undecided voter, and both sides try to sway him toward their candidate of choice.
"When I was as little girl, I didn't think that I could ever be president, and do you know what that was? Because no woman had ever been president of these United States," Adler said. "If you help elect Hillary Rodham Clinton, you -- just you! -- will be a part of the America that finally shattered that glass ceiling."
Spoiler alert: McFarland decides to vote for Clinton -- but not because of Adler's speech. In the end, he announces, "I'm with her" because Katy Perry is too.
