Even portraying Donald Trump leads to constant controversy.

Alec Baldwin dropped by Jimmy Kimmel Live last night and delivered his own semi-State of the Union on all things Donald Trump. Baldwin told a story in which he revealed that his divisive Trump impression, a staple of this season’s Saturday Night Live, was something he developed off the cuff, divulging that he had no idea what he was going to right up until the first dress rehearsal three and a half hours before the show.

But the originality of Baldwin’s Trump impression has been a source of controversy. Back in October, Decider reported on the possibility of Baldwin “borrowing” his Trump impression from another comic, Anthony Atamanuik. Atamanuik, who had portrayed Trump since the beginning of his presidential campaign and repeatedly showcased his impression on Comedy Central’s @midnight, previously worked with Baldwin on 30 Rock (Atamanuik portrayed one of the non-speaking writers).

During his chat with Kimmel, Baldwin referenced Atamanuik’s impression and said there are people “lobbying to play Trump at the White House Correspondents Dinner.” Baldwin didn’t refer to the comedian by name, instead calling Atamanuik “a guy who’s on the internet.”

“It’s interesting that now that [Trump’s] not going to the White House Correspondents’ Dinner, there are people who are lobbying to play Trump at the White House Correspondents Dinner,” Baldwin told Kimmel, clearly referring to Atamanuik. “There’s a couple guys on the internet who are like, ‘No, please. I’m the only man who should play Trump.’ There’s a lot of Trump competition; I got sucked into this.”

“Nobody even knows who these guys are,” Kimmel replied (which is, well, not accurate).

After Trump announced that he would not be attending the White House Correspondents’ Dinner, Atamanuik volunteered his services via Twitter, offering to play the president at the event. As SplitSider reports, this idea was met with an overwhelmingly positive response from the comedy community as a number of notable names — including Mark Hamill, Paul F.Tomkins, Ben Schwartz, Lake Bell, and Chris Gethard — voiced their enthusiastic support.

For Baldwin, the virtual war of words was far from over. James Adomian, who played Bernie Sanders to Atamanuik’s Trump in a nationwide tour, took to Twitter to lash out at the actor in a series of tweets.
