As Trump was fighting off his Republican competitors in Detroit on Thursday night, Cohen unleashed a satirical attack of his own on the presidential hopeful. The British comedian, 44, attended Los Angeles premiere of his latest film, The Brothers Grimsby, where he pretended to publicly support Trump's campaign.
"Today I am announcing my endorsement of Donald Julio Trump for President," said Cohen, acting in character as Nobby from the film.

And if his speech wasn't enough, Cohen certainly dressed for the part. He was decked out in Trump campaign gear, including a "Make America Great Again" baseball cap.
He continued his mock endorsement while talking to reporters, describing Trump, 69, as a "demagogue."
"I am swearing allegiance to him," he said. "He is a fantastic bloke, and the great thing that history has shown is getting a demagogue who speaks at rallies, spreading racial abuse, never leads to anything bad."
He continued: "It always works out and I'm just a big, big fan of him. He's the ultimate football hooligan. He listens to what people say and then he kicks their f---ing heads in."
Cohen's ribbing comes after the film made headlines when it was revealed that Trump (along with Harry Potter star Daniel Radcliffe) contracts AIDS during a skit in The Brothers Grimsby.
A Sony spokesperson refuted reports Cohen was pressured to cut the controversial scene from the film, telling Entrainment Weekly the studio is "100 percent supportive of the filmmaker and film."
The Brothers Grimsby hits theaters March 11.
