Well, for anybody that thought Donald Trump was going to take his recent series of setbacks gracefully, you can set your minds at ease:

In an angry letter to David Letterman, Donald Trump claims he is pulling out of a scheduled May 18 appearance on CBS’ Late Show because the late night show host has called him a racist.

Got pwned by the President at the correspondent's dinner? Had your cheesy reality show interrupted by news of bin Laden's death? No worries, just take on the mighty David Letterman, maybe that's a battle you could actually win. Actually, probably not.

Letterman's offense? Seems Dave saw all the birth certificate horseshit for what it was:

On CBS’ Late Show Thursday, David Letterman suggested he might not invite the potential presidential candidate back on his show unless he apologizes for his attacks on President Obama...

...“It’s all fun, it’s all a circus, it’s all a rodeo, until it starts to smack of racism. And then it’s no longer fun,” Letterman told his guest Dr. Phil (a Trump pal).

That's right, Trump isn't "pulling out of" anything. Letterman's already fired him.
