Katy Perry is "deeply appalled and angry" after President Donald Trump used her song Firework to accompany footage of US strikes on Iran. She wrote on X: “I am deeply appalled and angry to see ‘Firework’ used on the White House TikTok as a backing track for video footage of military strikes. The Dark Horse hitmaker is the latest in a string of stars to condemn the Trump administration for using their music in social media posts. A White House spokesperson defended the video, saying: “What’s actually barbaric, inhumane, and heinous are the criminal illegal aliens who have injured and murdered innocent American citizens.” In addition, Kesha complained after Blow was used in a military video, Sabrina Carpenter objected to an "evil and disgusting" ICE video featuring Juno, and Olivia Rodrigo condemned the White House for using her music to promote “racist, hateful propaganda”.
