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

The T-shirts, which sell for $36, include a Trump image in the foreground, with different photos of him on a grid in the background. The design is an imitation of the poster for Swift’s billion-dollar-grossing tour, which is also sold on T-shirts and various other merchandise. Trump’s campaign touted the product on X, calling it a “Trump Era shirt.”

It’s unclear what, if any, legal action Swift could take against Trump, who is already facing a host of notices from musicians and their estates to stop using their music at his campaign events. Swift is famously cautious about her public image, and her publicist is known to be intensely protective. Swift has yet to respond publicly to the campaign’s promotion.

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