C.K.'s take-no-prisoners brand of stand up comedy apparently rubs Van Susteren the wrong way. "Louis C.K. Comedian? I don't think so. Pig? Yes," she wrote on her blog on March 8.

The Fox News host included a few choice quotations from C.K.'s Twitter and stand up, which she argued made attending the event unconscionable. "I refuse to show any support for this guy or for the Radio and Television Correspondents Association Dinner Committee who hired him," she added. "I think the organization that hired him is just as bad as he is. It is no secret that he denigrates women."

According to CNN's Peter Hamby, however, Van Susteren's blustering wasn't to blame for the Emmy award-winning comedian's decision to drop out:

C.K. is the creator and star of "Louie," a semi-autobiographical FX original series in which C.K. plays a fictionalized version of himself. The show chronicles his trials and tribulations of raising two daughters as a divorcé in New York City.
