President Trump's re-election campaign found itself in hot water with the Prince estate after "Purple Rain" was played in the run-up to the president's rally appearance on Thursday.
Several videos taken inside Target Center showed fans singing along to Prince's most famous hit, which later brought a response from the Prince estate on Twitter.
"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," it wrote.
"The Prince estate will never give permission to President Trump to use Prince’s songs."
The estate posted with the tweet a letter it had received a year ago from the campaign's lawyers, confirming they would refrain from using Prince's music in any of events going forward.
There have been multiple occasions in recent years in which musical acts have objected to their songs being used at the president's campaign events, among them Adele, The Rolling Stones, Queen and the estate of The Beatles' George Harrison.
While playing Prince songs is customary for the warmup of many events in the Twin Cities, its use on Thursday sparked some backlash online.
