The actor opened the show as Trump, worrying about Robert Mueller's upcoming Special Counsel investigation into Russia's meddling in the last U.S. election.
Speaking on the phone to his ex-attorney Michael Cohen, played by Ben Stiller, Alec's Donald said, "God, I haven't been this upset since I flipped out over that parking space."
This was Alec's first appearance on the show since he got busted last month for trying to punch a guy who nabbed his parking spot. He is facing one count of attempted assault in the third degree, and one count of harassment in the second degree.
Saturday night's show, hosted by British actress Claire Foy, also featured a tribute to President George H.W. Bush following his death on Friday night (November 30).
