First son Donald Trump Jr. took a swipe at Alec Baldwin over allegations that the actor punched a man in a Friday dustup over a parking space.

“I guess Don Lemon was referring to Alec Baldwin when he said white men are the biggest terror threat,” Trump wrote on Twitter, referring to the CNN host’s on-air comment from Monday.

Trump followed up with a reference to Baldwin’s infamous rant in 2013, when the ever-aggravated actor used homophobic slurs against a Post photographer.

“Don’t forget the homophobic slurs. Other than all of those things and all of those chances he’s been given he seems wonderful,” Trump said of Baldwin, who’s mockingly impersonated the president on “Saturday Night Live.”

Trump’s Saturday tweets followed a Friday post in which he called his father’s nemesis “a piece of garbage” in reference to the parking fracas.

Baldwin, who has a history of embarrassing blowups, denied striking fellow driver Wojciech Cieszkowski on Friday. The Bloviator said “the assertion that I punched anyone over a parking spot is false.”
