Elon Musk pokes fun at Green Day's performance slamming Trump's 'MAGA agenda'

Tesla CEO Elon Musk called out Green Day after frontman Billie Joe Armstrong made an anti-Trump remark at the "Dick Clark’s New Year’s Rockin’ Eve" special on Sunday.

Singing the lyrics to the band's hit 2004 tune "American Idiot," Armstrong subbed the song's "I’m not a part of the redneck agenda" verse for the line, "I’m not a part of a MAGA agenda."

Writing on X on Monday, Musk accused the pop-punk band of straying from its roots.

"Green Day goes from raging against the machine to milquetoastedly raging for it," Musk wrote, adding laughing emojis.

The band, which formed in California's East Bay in 1987, has been vocally critical of conservative politicians for decades.

In a 2016 interview with Kerrang! magazine, Armstrong compared former President Trump to Adolf Hitler.

"The worst problem I see about Trump is who his followers are," Armstrong said. "I actually feel bad for them because they're poor, working-class people who can't get a leg up. They're just p---ed off, and he's preyed on their anger."

"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!" the "Basket Case" singer added.

During a concert in 2018, Armstrong told his French audience that he "f---ing hate[d] Donald Trump so much."

"I used to scream I hated George Bush," the frontman said. "This one is a little different. This one is bad, it’s like acid gone bad. F---ing LSD and the American right, man."
