Rock band Aerosmith has been rather vocal about their distaste for seeing Donald Trump use their music at his campaign rallies. In fact, band member Steven Tyler has hit the incumbent President with a cease-and-desist letter demanding he stops playing his music at his events.

STEVEN TYLER SENDS TRUMP A CEASE-AND-DESIST LETTER

Dina LaPolt, Tyler’s lawyer, writes in the letter that Trump’s persistent usage of “Livin’ On The Edge” implies its creators endorse his rhetoric, writing, “By using ‘Livin’ On The Edge’ without our client’s permission, Mr. Trump is falsely implying that our client, once again, endorses his campaign and/or his presidency, as evidenced by actual confusion seen from the reactions of our client’s fans all over social media.”

Tyler has threatened legal action should Trump fail to comply with his request. He also took to Twitter to clarify why he wants Trump to stop using his music, explaining that this isn’t a partisan issue, it’s one of songwriters’ rights:

Politicians using artists’ music without their blessings is a recurring problem. Mitt Romney accrued complaints from Al Green, K’Naan and Silversun Pickups for playing their work during his rallies back during the 2012 presidential election. Trump has perviously utilized popular music tracks during his rallies to the ire of their artists; in fact, this isn’t even the first time Tyler sent him a cease-and-desist letter.
