Trump blasts Seinfeld pullout

The New York Post reports:

Donald Trump wasn't laughing when funnyman Jerry Seinfeld canceled an upcoming appearance at a benefit for his son's Eric Trump Foundation.

Seinfeld pulled out of the Sept. 13 event benefiting the St. Jude Children's Research Hospital because he disagrees with The Donald's questioning of Barack Obama's citizenship, his reps said.

"I just learned you canceled a show for my son's charity," Trump fired off in a scorching letter to Seinfeld yesterday, "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."

Seinfeld doesn't think questioning Barack Obama is funny. No word yet on Seinfeld giving up most of his wealth to the IRS.
