What is Kamala Harris's 'brat' rebrand all about?

Kamala Harris has overhauled her campaign's online presence by embracing a social media trend inspired by pop star Charli XCX's Brat album cover.

The presumptive Democratic presidential nominee has scattered references to the album across her campaign's account, renaming her profile Kamala HQ.

Her rebrand comes as Charli showed her support by tweeting "kamala IS brat" shortly after President Joe Biden announced he was stepping out of the race for the White House and endorsed his vice-president.
