Famed television comic Jerry Seinfeld has pulled out of an event connected to Eric Trump, son of Donald Trump, because of the latter’s aggressive attacks on President Barack Obama, particularly his insistence that Obama was not born in the U.S., according to a report on CNN.

Seinfeld was slated to attend an event on September 13 for a charity called The Eric Trump Foundation, which benefits St. Jude’s Children’s Research Hospital,

Seinfeld, 56, agreed to appear in the benefit back in January, but according to representative, the comic became “increasingly uncomfortable” with Trump’s repeated questioning of Obama’s citizenship.

According to his manager, Seinfeld “feels this kind of demagoguery has no place in public discourse… He has respectfully withdrawn from the event, and is making a contribution both to the Eric Trump Foundation and to [St. Jude].

Trump angrily responded to Seinfeld’s decision with a letter in which h wrote: I just learned you canceled a show for my son's charity, The Eric Trump Foundation, which benefits the St. Jude's Children's Research Hospital [children with cancer] because of the fact that you think I am being very aggressive with respect to President Obama, who is doing an absolutely terrible job as our leader - just look at Libya, our economy, gas, food, and clothing prices and maybe you will understand what is going on!

An irate Trump further wrote that “the children of St. Jude are very disappointed and Bret Michaels [former rock star], disgusted by what happened, is taking over.

Trump added: 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.
