Former President Donald Trump responded to Taylor Swift’s endorsement of Vice President Kamala Harris on Tuesday after the “Tortured Poets Department” singer backed the Democratic nominee.

Trump was asked about Swift’s statement in the spin room, an area where reporters are able to ask candidates and their surrogates questions after a debate. He replied, “I have no idea.”

Shortly after the presidential debate ended Tuesday night, Swift shared a photo of her with her cat, Benjamin Button, to Instagram and wrote in the caption that she will be supporting Harris and Tim Walz. Swift also acknowledged Trump’s use of AI-generated images depicting her endorsing him and said it made her realize she needed to be clear about her actual plans for the election. The pop star signed off the post labeling herself a “Childless Cat Lady,” taking a jab at JD Vance’s now-viral comments about people who don’t have children.

In the four-paragraph endorsement, Swift encouraged her 283 million followers to do their own research ahead of the election this fall and to vote.

“Like many of you, I watched the debate tonight. If you haven’t already, now is a great time to do your research on the issues at hand and the stances these candidates take on the topics that matter to you the most,” Swift wrote. “As a voter, I make sure to watch and read everything I can about their proposed policies and plans for this country.”

On Fox & Friends the next morning, Trump said he prefers Swift’s friend and MAGA fan Brittany Mahomes, who is the wife of Kansas City Chiefs quarterback Patrick Mahomes, who entered the singer’s social circle when she began dating Chiefs tight end Travis Kelce last year.

In a Truth Social post last week, Trump thanked Mahomes for her apparent support of his campaign after she reportedly liked and un-liked one of his posts detailing the 2024 GOP platform on Instagram. She also reportedly liked and un-liked a comment that simply said “TRUMP-VANCE 2024” on one of her Instagram posts.

“(Swift) seems to always endorse a Democrat, and she’ll probably pay a price for it at the — in the marketplace. But, no, I like Brittany,” Trump said Wednesday. “That’s the one I like, much better than Taylor Swift… I think she’s terrific. Not Taylor Swift.”

It’s not the first time Swift has backed a political candidate. She endorsed President Joe Biden and Harris in 2020, and she backed U.S. Senate candidate Phil Bredesen and U.S. Rep. Jim Cooper in his 2018 re-election bid to Tennessee’s 5th Congressional District.
