The newest high-profile celebrity to show support for Kamala Harris in the run-up to the November election is Billie Eilish, and fans of the MAGA movement are incensed by this development.

The music diva, who is 22 years old, and her older brother, Finneas, have both expressed their opinions on the political situation in a message that they have shared with their combined 123 million followers on Instagram.

The award-winning sibling duo made the public plea to fans on Tuesday. “Today is National Voter Registration Day, and we are asking you to please join us in going to iwillvote.com to check your status and vote early like we do,” Finneas stated.

“We are voting for Kamala Harris and Tim Walz because they are fighting to protect our reproductive freedom, our planet, and our democracy. We can’t let extremists control our lives, our freedoms, and our future," Billie went on.

"The only way to stop them and the dangerous Project 2025 agenda is to vote and elect Kamala Harris,” Finneas added. “Vote like your life depends on it because it does,” the “Bad Guys” hitmaker went on.

"It’s National Voter Registration Day. We are voting for Harris-Walz. The choice is clear. Check your voting status here: iwillvote.com,” Billie and Finneas captioned their joint Instagram post.

The "extremism" that Billie and Finneas are referring to is Project 2025, which is a plan that is 900 pages long and was drafted by the advisers of Donald Trump. It is supported by influential individuals on the right.

A detailed plan to increase his executive authority, replace civil servants with ideologically aligned nominees, kill abortion rights, and enforce an anti-immigrant agenda are among the ideas that are included in this document, which is essentially a wishlist for his government.

Additionally, the artist who won a Grammy uploaded her endorsement video on X, where followers of Donald Trump were not shy about communicating their opinions regarding the matter, Daily Express reported.

"Yawn. Nobody cares," One user @EndWokeness replied to the video. "You sound like you read a script…" @Liberacrat claimed. "This is the rhetoric that’s gotten Trump shot at twice!! Project 2025 is NOT Trump's agenda,” a third X user stated. "I’m voting for Trump. I don’t have hundreds of millions of dollars,” another netizen penned.

"Another ignorant couple of Hollywood liberals. ‘Reproductive freedom’ is Kamala’s way of whitewashing infant*c*de. President Trump doesn’t support Project 2025. We’re not a democracy, [but] rather a constitutional republic. Eilish is totally clueless and should stick to music,” a fifth source wrote on X, formerly Twitter.
