The sources said Van Susteren sought to renegotiate the terms of her contract -- and asked for a big bump in pay -- after Ailes resigned.Van Susteren claims she left of her own accord:
Fox executives refused to negotiate, one of the sources said.
There was a "financial disagreement," another one of the sources said.
"On Thursday night, I made my decision and informed Fox News of my decision that I was leaving Fox News Channel per my contract," Van Susteren wrote on her Facebook page Tuesday. "Fox has not felt like home to me for a few years and I took advantage of the clause in my contract which allows me to leave now. The clause had a time limitation, meaning I could not wait."UPDATE: CNN Money reports that FOX pulled the trigger:
A courier arrived at Van Susteren's Washington, D.C. home at 9 a.m. Tuesday, hand-delivering two letters that said that Van Susteren "was being taken off the air" immediately, according to her husband, John Coale, who is a high-profile Washington lawyer.
Van Susteren was already planning to leave, but she thought she would be hosting her 7 p.m. program "On the Record" for a few more weeks.
Yanking her off the air without a chance to say goodbye was "a bit immature," Coale remarked.
