The actor appeared "The Late Show" Tuesday night, and host "Saturday Night Live" role. Baldwin described his Trump as "totally a caricature," and explained the strange ways he has to contort his face while in character.
"Left eyebrow up, right eyebrow down. Shove your face out like you're trying to suck the chrome off the fender of a car," he told Colbert.
It definitely isn't an easy face to make, let alone hold for the duration of an entire "SNL" sketch, we'd imagine. Still, people love it. Baldwin shared that strangers always stop to thank him for his Trump impression while he is out and about in New York, to the point that it's "eerie."
Watch the full interview below, beginning around 1:00. Colbert and Baldwin start talking the "SNL" version of Trump around 3:15.
"The Late Show with Stephen Colbert" airs weeknights at 11:35 p.m. ET/PT.
