Trump campaign is selling Eras Tour-inspired shirts. Swifties call it his 'cease & desist era'.

Former President Donald Trump is selling t-shirts with a similar aesthetic as the Taylor Swift Eras Tour merchandise.

One of the world's biggest pop stars endorsed Trump's opponent Vice President Kamala Harris after Tuesday's presidential debate , saying, "(Harris) fights for the rights and causes I believe need a warrior to champion them," and taking a subtle jab at Republican vice presidential nominee JD Vance 's viral comments about " childless cat ladies. "

The Trump campaign posted about the new merch Thursday morning, calling on "Swifties for Trump" to buy the "Trump Era shirt."

The shirt is printed with a black-and-white silhouetted photo of Trump in front of colored tiles containing other photos of him, including his mugshot taken while he was booked in Atlanta on charges that he tried to steal the election.

Even the X account "Swifties for Trump" wondered if he made the shirts before or after the endorsement:

'In your cease & desist era': Swifties respond to the new Trump shirt

Hundreds of people on X responded to the post, many of them tagging Swift and her publicist Tree Paine, and suggesting a lawsuit against Trump.

"In your cease & desist era," one user quipped.

USA TODAY reached out to Paine and the Trump campaign for comment.

The Harris campaign is now selling friendship bracelets, a common token among Swifties.

Trump shared AI-generated images of Swift

This isn't the first online political stunt Trump has pulled aimed at Swift. In Swift's endorsement, she mentioned apparent AI-generated images that suggested Swift supported his campaign. Trump shared them before she weighed in on the 2024 election, but she had endorsed President Joe Biden in 2020.

"Recently I was made aware that AI of ‘me’ falsely endorsing Donald Trump’s presidential run was posted to his site. It really conjured up my fears around AI, and the dangers of spreading misinformation," Swift said in her Tuesday Instagram post. "It brought me to the conclusion that I need to be very transparent about my actual plans for this election as a voter."
