Donald Trump has rejected Taylor Swift’s endorsement of his election rival, but it appears his campaign is still hoping to leverage her image for support. On Thursday, his campaign announced new Trump shirts that are blatant knockoffs of Swift’s “Eras” tour poster.

The T-shirts, which retail for $36, feature an image of Trump in the foreground, with several photos of him on a grid in the background. The design is a knockoff of the poster for Swift’s multibillion-dollar tour, which is also being sold on T-shirts and various other merchandise. Trump’s campaign promoted the product on X, calling it a “Trump Era shirt.”

It’s unclear what legal action, if any, Swift might take against Trump, who has already faced a series of requests from musicians and their families to stop using their music at his campaign events. Swift is notoriously cautious about her public image, and her publicist is known to be fiercely protective. Swift has not yet publicly commented on the campaign promotion.

But the pettiness of the move suggests the former president is more irked by Swift’s endorsement of Kamala Harris than he has let on. Last week, Trump suggested on Fox News that Swift’s endorsement would affect her “marketplace success” and said he was not a fan.

“I actually like Ms. Mahomes a lot better, if you want to know the truth,” Trump said, referring to Brittany Mahomes, the wife of Kansas City Chiefs quarterback Patrick Mahomes and a friend of Swift’s who has publicly supported Trump. “She’s a big Trump fan. I was not a Taylor Swift fan.”

Yet Trump has done everything he can to Using Swift’s popularity to his advantage. In August, he posted several AI-generated images of the pop star and her fans, known as “Swifties,” on Truth Social in support of him. Swift said in her statement of support for Harris that she was motivated in part by the fake images, writing, “It made me realize that I need to be very transparent about my true plans for this election as a voter.”

Swift has spoken out against Trump a few times over the years. Earlier this year, however, Trump said he didn’t believe Swift would support President Joe Biden in 2024 because Trump signed bipartisan legislation to reform copyright law in 2018, arguing that she wouldn’t “be disloyal to the man who made her so much money.” (This is despite Swift previously endorsing Biden in 2020.)

Trump has also expressed disbelief that “a country star can be successful by being liberal” (Swift started out making country music but has since gone in a decidedly pop direction), asking if “she’s a liberal, or is that just an act?”
