Green Day lead singer Billie Armstrong compared Donald Trump to Adolf Hitler in an upcoming issue of the U.K. magazine Kerrang.

“The worst problem I see about Trump is who his followers are,” Armstrong said, according to UPROXX. “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.” (RELATED: Green Day’s Billie Joe Armstrong Getting Treatment After Onstage Meltdown)

“He just said, ‘You have no options and I’m the only one, and I’m going to take care of it myself,'” he told Kerrang. “I mean, that’s f–king Hitler, man! I don’t even know how else to explain it.” (RELATED: Which Green Day Song Is On Paul Ryan’s iPod?)

“I wish I were over-exaggerating,” he continued. “And sometime maybe I do over-exaggerate with [George W] Bush. But with Trump, I just can’t wait ’til he’s gone.”
