Donald Trump is not a big fan of Jerry Seinfeld after the comedian reportedly pulled out from an event appearance for the Donald's son's charity.
Seinfeld was scheduled to attend a September 13 event for St. Jude Children's Research Hospital and the Eric Trump Foundation, but he canceled.
According to reports, Jerry bailed based on Trump's remarks about President Obama, which didn't sit well with The Donald for a variety of reasons.
"I just learned you canceled a show for my son's charity," Donald Trump wrote to Seinfeld in an open letter, accusing him of backing out simply:
"Because of the fact that I am being very aggressive with respect to President Obama, who is doing an absolutely terrible job as our leader."
Trump, who is considering a 2012 presidential run, didn't stop there.
"We don't care that you broke your commitment," he continued, "Even though the children of St. Jude are very disappointed, and despite the fact that your manager previously and clearly stated you are 'truly a man of his word.'"
Trump then took a shot at Seinfeld's NBC show, The Marriage Ref."What I do feel badly about is that I agreed to do, and did, your failed show, 'The Marriage Ref,' even though I thought it was absolutely terrible."
"Despite its poor ratings, I didn't cancel on you like you canceled on my son and St. Jude. I only wish I did."
A rep for Seinfeld said he agreed to appear at the event before Trump began questioning the authenticity of Obama's birth certificate. However, "Jerry has grown increasingly uncomfortable" with the Apprentice head honcho.
"Jerry ... feels this kind of demagoguery has no place in public discourse," said the rep. "He has respectfully withdrawn from the event, but is making a contribution both to the Eric Trump Foundation and to [St. Jude]."
Bret Micheals is slated to fill Seinfeld's place, the rocker said in a statement.
"Donald Trump and his family have been wonderful to me and St. Jude's Children's Hospital is one of my favorite charities, so I'm honored to have been asked by Eric and the rest of the Trump family to be a part of this event," he said.
"We should never allow the spirit of generosity to be overshadowed by divisive political beliefs," Bret added in a dig at Seinfeld, "and when it comes to saving the life of a child, there is absolutely no room for political rhetoric."
