Billie Eilish tells fans to vote for Kamala Harris 'like your life depends on it, because it does'

Billie Eilish and Vice President Kamala Harris are birds of a feather.

The "Bad Guy" singer, 22, and her brother Finneas, 27, endorsed Harris' 2024 presidential campaign in a video shared Tuesday, which was National Voter Registration Day.

Eilish said she and her brother are voting for Harris and her running mate, Minnesota Gov. 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," Finneas said. "The only way to stop them and the dangerous Project 2025 agenda is to vote and elect Kamala Harris."

Eilish added, "Vote like your life depends on it, because it does."

Former President Donald Trump has distanced himself from Project 2025, a controversial series of policy proposals for the next administration created by the Heritage Foundation and other conservative groups.

Taylor Swift'sresponse to presidential debate? She quickly endorsed Kamala Harris.

"I haven't read it," Trump claimed during last week's presidential debate with Harris. "I don't want to read it, purposely. I'm not going to read it. This was a group of people that got together, they came up with some ideas. I guess some good, some bad. But it makes no difference."

Harris alleged Trump "intends on implementing" the "dangerous" plan if elected.

Following the endorsement, Harris' campaign released an ad on Wednesday featuring Eilish's song "When the Party's Over." In the ad, a woman says she "had options" after she was abused and impregnated by her stepfather at age 12 but that after the Supreme Court overturned Roe v. Wade, "girls and women all over the country have lost the right to choose."

Eilish, a nine-time Grammy winner whose music is hugely popular with young people, previously endorsed President Joe Biden in the 2020 election and performed at that year's Democratic National Convention. The singer, who had become eligible to vote when she turned 18 the year prior, said at the time that Trump was "destroying our country and everything we care about."

Bad blood:Donald Trump says 'I hate Taylor Swift' after she endorsed Harris

"We need leaders who will solve problems like climate change and COVID, not deny them," she said. "Leaders who will fight against systemic racism and inequality, and that starts by voting for someone who understands how much is at stake, someone who's building a team that shares our values. It starts with voting against Donald Trump and for Joe Biden. Silence is not an option, and we can't sit this one out."

Eilish's endorsement comes after Taylor Swift backed Harris last week following the vice president's debate with Trump. In an Instagram post, the pop star said she is voting for Harris "because she fights for the rights and causes I believe need a warrior to champion them," adding that she is "a steady-handed" and "gifted leader," and "I believe we can accomplish so much more in this country if we are led by calm and not chaos."

Trump responded by posting an all-caps message on his social media platform Truth Social that simply read, "I hate Taylor Swift," prompting fellow celebrities to champion Swift with posts saying, "I love Taylor Swift."
