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.
