Democrat Vice President Kamala Harris said during Tuesday's debate with Republican Donald Trump that she owns a gun, a revelation that surprised some voters but carried a deliberate political message.

"Vote like your life depends on it because it does," the pop artist said alongside her brother in a video shared on social media.

Billie Eilish and Finneas are voting the color of the final track on their May album, Hit Me Hard and Soft: blue. In honor of National Voter Registration Day, the sister-brother musical duo endorsed Kamala Harris' presidential campaign and urged fans to get to the polls this November to help stop what they called an "extremist" agenda from Republicans.
