Sinead O'Connor's estate sent a cease and desist letter demanding Donald Trump stop using her song "Nothing Compares 2 U" at his political rallies. This came after the estate learned Trump had been playing the song, which violates O'Connor's moral code. O'Connor was a vocal critic of Trump and called him the "biblical devil" in past interviews. She passionately criticized his policies separating families at the border and felt he was unfit for office. O'Connor's estate joined many other artists who have banned Trump from using their music at rallies.
