Trump complained on Twitter that the network wasn't treating him fairly:
.@FoxNews has been treating me very unfairly & I have therefore decided that I won't be doing any more Fox shows for the foreseeable future.
— Donald J. Trump (@realDonaldTrump) September 23, 2015
The announcement came after the real estate mogul renewed his feud with Fox News anchor Megyn Kelly in a Tuesday night rant.
Update: A Fox News spokesperson said in a statement provided to TPM that the network canceled Trump's planned Thursday appearance on "The O'Reilly Factor" before he announced that his boycott:
“At 11:45am today, we canceled Donald Trump’s scheduled appearance on The O’Reilly Factor on Thursday, which resulted in Mr. Trump’s subsequent tweet about his ‘boycott’ of FOX News. The press predictably jumped to cover his tweet, creating yet another distraction from any real issues that Mr. Trump might be questioned about. When coverage doesn’t go his way, he engages in personal attacks on our anchors and hosts, which has grown stale and tiresome. He doesn’t seem to grasp that candidates telling journalists what to ask is not how the media works in this country.”
