Aerosmith frontman Steven Tyler is asking Republican presidential candidate Donald Trump to stop using the power ballad "Dream On" at campaign events. The letter says that Trump does "not have our client's permission to use 'Dream On'" or any of Tyler's other songs and that it "gives the false impression that he is connected with or endorses Mr. Trump's presidential bid." Attorney Dina LaPolt said in a statement that the letter is not a "political" or "personal issue with Mr. Trump," but it's one of permission and copyright. Trump called himself earlier this week"a big Second Amendment person" and argued that if someone had been carrying a gun during the shooting at Umpqua Community College in Roseburg, Oregon earlier this month, " the result would've been better."
