Taylor Swift endorsed Kamala Harris for president just minutes after the Democratic nominee's presidential debate against her Republican opponent, Donald Trump. 

Writing on Instagram, the pop star said she will be voting for Harris because, "she fights for the rights and causes I believe need a warrior to champion them."

"I’ve done my research, and I’ve made my choice. Your research is all yours to do, and the choice is yours to make. I also want to say, especially to first time voters: Remember that in order to vote, you have to be registered!" Swift wrote to her 283 million followers. "I also find it’s much easier to vote early. I’ll link where to register and find early voting dates and info in my story."

Swift signed the post: "Taylor Swift, Childless Cat Lady," a nod to Trump's running mate J.D. Vance, who said during a 2021 interview: "We are effectively run in this country, via the Democrats, via our corporate oligarchs, by a bunch of childless cat ladies who are miserable at their own lives and the choices that they’ve made, and so they wanna make the rest of the country miserable, too."

Within minutes, the post had garnered more than 2 million likes.

Swift's endorsement came after some of her fans gave Brittany Mahomes flak for supporting Trump. 

Mahomes, a 29-year-old pregnant mother, first indicated her support for Trump on Aug. 13 when she liked Trump's Instagram post that outlined the "2024 GOP platform."
