Ahead of a press event on Monday in New Hampshire, Donald Trump assured reporters he had patched things up with Aerosmith frontman Steven Tyler. 

"It's all been worked out," he said.

Trump was referring to a second cease-and-desist letter sent to the Republican candidate on Saturday from Tyler's attorneys, demanding that the Trump campaign no longer use "Dream On." 

The letter stated that Trump did "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."

Tyler, who is a registered Republican, attended the GOP contenders' first debate in August.

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.
