Reply #4: The story's a little confusing...the Kimball bit came from the NY Post

...the Post story quotes Fox, but the information revealing Kimball as the author came from the Post. Because it's "nested" in the story, it does indeed appear to be 100% Fox:

CHEF NEEDS JOB

March 23, 2006 -- ISAAC Hayes may not have quit "South Park" at all - or at least not willingly. Turns out Hayes has been away from Comedy Central's hit show for the past three months because he had a stroke. According to foxnews.com, he's at home recuperating and did not issue the press release which said he was quitting because the show made fun of his faith. That release was put out by fellow Scientologist Christina "Kumi" Kimball, a fashion executive for designer Craig Taylor. According to foxnews.com, "Hayes loves 'South Park' and needs it for income. He has a new wife and a baby on the way."
