Actor Mickey Rourke unloaded on Donald Trump in an expletive-filled rant Wednesday night, calling the GOP presidential frontrunner “the biggest scumbag on the planet” whose wife, Melania, is “one of the biggest golddiggers around” — while threatening to beat the candidate with a baseball bat. “Before I throw this first pitch out, I just want to say — the biggest scumbag on the planet is that maggot with an ‘f’ in front of it, Donald Trump,” the 63-year-old action star told TMZ while playing a game of catch with a friend in Beverly Hills Wednesday night. “F*ck him, f*ck the horse he rode in on,” Rourke continued, adding: “I think his wife is one of the biggest golddiggers around. I know, I used to go out with a golddigger. I mean, how could you sleep next to that flabby, fat piece of sh*t and get your rocks off? Motherf*cker’s gotta have millions sticking out of his a**hole, I mean, you’ve gotta go to bed with that every night? You’ve gotta be a golddigger.” The former boxer-turned-movie star told TMZ that Trump had sued him and the rapper 2Pac several years ago, though it was unclear what he had allegedly been sued
