President Donald Trump didn’t keep up his end of the deal when he played late singer Prince’s iconic hit “Purple Rain” after his campaign event in Prince’s hometown Thursday (Oct. 10).

At least that’s what Prince’s family is saying.

Prince’s Twitter account called out Trump and wrote,

“President Trump played Prince’s “Purple Rain” tonight at a campaign event in Minneapolis despite confirming a year ago that the campaign would not use Prince’s music. The Prince Estate will never give permission to President Trump to use Prince’s songs.”

Attached to the tweet was a letter from a law firm that said no Prince music would be played at any Trump events moving forward. The letter, which is dated Oct. 15, 2018, reads:

“Our client Donald J. Trump for President, Inc. (the ‘Campaign’) is in receipt of your letter of October 11, 2018. Your letter requests, on behalf of the Estate of Prince Rogers Nelson (“Prince”), that the Campaign refrain from using Prince’s “Purple Rain,” or any other Prince music, in connection with the Campaign rallies or other Campaign events. Without admitting liability, and to avoid any future dispute, we write to confirm that the Campaign will not use Prince’s music in connection with its activities going foward.”
