Billie Eilish and her brother Finneas have announced their endorsement of Kamala Harris and Tim Walz’s 2024 presidential campaign in a video posted to social media on Tuesday, 17 September. The “Lunch” singer, 22, and the producer, 27, threw their support behind the Democrats in a clip posted to coincide with National Voter Registration Day. Eilish explained that she supported Harris-Walz as they “are fighting to protect our reproductive freedom, our planet, and our democracy,” while Finneas warned: “The only way to stop them and the dangerous ‘Project 2025’ agenda is to vote and elect Kamala Harris.”
