Green Day's Billie Joe Armstrong calls Donald Trump 'f***ing Hitler'

The hits just keep on coming for Green Day. Frontman Billie Joe Armstrong — a vocal critic of the George W. Bush administration and not one to hide his political views — is taking aim at another Republican heavyweight.

In an interview with Kerrang, Armstrong slammed presidential candidate Donald Trump, saying the billionaire reminds him of Hitler, a comparison he isn't alone in making.

"He just said, 'You have no options and I'm the only one, and I'm going to take care of it myself.' I mean, that's f—ing Hitler, man!" Armstrong proclaimed, likely referring to Trump's convention speech.

"I don't even know how else to explain it," he continued. "I wish I were over-exaggerating. And sometimes maybe I do over-exaggerate with Bush. But with Trump, I just can't wait 'til he's gone."

Armstrong's choice words didn't stop there. He also said "the worst problem I see about Trump is who his followers are."

"I actually feel bad for them, because they're poor, working-class people who can't get a leg up. They're pissed off and he's preyed on their anger," he added.

Armstrong's political jabs date back to the George W. Bush administration; Green Day's 2004 album "American Idiot," and it's songs "American Idiot" and "Holiday" directly addressed his presidency.

The rocker joins a slate of other notable celebrities and Hollywood execs who have taken shots at Trump. Earlier this year, George Clooney called Trump an "opportunist" and a "xenophobic fascist" in an interview with the Guardian. In a recent Facebook post, NBC chairman Bob Greenblatt wrote a scathing critique of the Republican candidate.

"The sad state of affairs thanks to a pompous businessman turned reality TV star (whose show consistently ran LAST in its time period, by the way) who thinks speaking his mind is refreshing. It's actually corrosive and toxic because his 'mind' is so demented; and his effect will unfortunately linger long after he's been told to get off the stage," Greenblatt wrote.
