Billie Eilish and Finneas announced their backing for Kamala Harris and Tim Walz in a joint video in September 2024. It was National Voter Registration Day, and they asked viewers to register and make a plan to vote.
The endorsement belonged to the 2024 presidential campaign. Taylor Swift had recently backed the same ticket, adding to the attention around musicians’ political statements. This account looks back at that election’s debate; it does not describe a new endorsement in a later campaign.
What they said in the video
Reproductive freedom, the environment and democracy were the reasons Eilish gave for supporting the ticket. Finneas spoke against extremism and Project 2025. They were explaining their own political choice.
They also pointed viewers toward information on registering to vote. A statement of support does not put anyone on the voter roll; someone seeing the video could use the reminder to check what was required and make a plan.
The musicians’ reach helped the message circulate. It did not tell us how each listener would vote, or whether a fan who watched the clip would agree. A large following is an audience with different views, rather than a single group of voters.
Eilish had spoken during the previous election too
At the 2020 Democratic National Convention, eighteen-year-old Eilish performed and criticized Donald Trump. Her 2024 endorsement had that earlier political appearance behind it.
It would be inaccurate to describe the Harris-Walz video as her first public statement on an election. It would also go too far to read a political intention into every song or career decision. In this case there is no need to guess: the video was an explicit endorsement.
Why the endorsement drew attention
Eilish and Finneas had an audience well beyond people already following campaign announcements. Their video could reach a fan through a music account or an entertainment headline, with the registration reminder attached to the news.
It came in the same month as Taylor Swift’s endorsement of Harris. Eilish’s earlier appearance at the 2020 Democratic National Convention also gave the new statement a history: she had spoken about an election before.
The siblings explained their own choice. They couldn’t cast their listeners’ votes for them. A person might watch, register, disagree or move on, and the video alone doesn’t tell us which happened. That leaves a clear public record of an endorsement and an appeal to participate, rather than a count of votes delivered by a celebrity. Their public message remains available to revisit.
