Donald Trump is super pissed at Jerry Seinfeld for withdrawing from a charity event Trump's son, Eric organized to benefit St. Judes Children's Research Hospital.

Word is, Seinfeld withdrew from the event because of "The Donald's" constant questioning of President Barack Obama's citizenship.

The  Trumpster is not taking this lying down.  He fired back saying, Jerry Seinfeld should be ashamed of himself for canceling on a chartiy and even went personal calling Seinfeld's show "The Marriage Ref", quote, "a failed show'.

What do you think?  Should Donald worry less about President Obama's citizenship and more about his own hair? Or is he right on in your opinion?

Do you think Seinfeld was wrong to cancel?  Or do you think he made the right decision?
