O'Reilly interviewed on Glenn Beck's radio show, and complained of a "liberal hit job" and said his firing came about because of a left-wing cabal intent on "destroying voices (they don't) like".
O'Reilly was forced out of Fox News after 60-plus advertisers fled following revelations the network paid $13 million to settle five separate sexual harassment claims against him. "I was target No. 1, and it's sad".
"My attorneys told me, and we were all shocked. So, if that's what they felt was best for the company, I'm not going to hammer them", he said.

He said he and his legal team would soon be naming names of those they believe are behind a plot to get him fired.
Charles Herring, CEO of San Diego-based One America Network, told the paper's MediaBlast blog: "Bill O'Reilly has been nothing short of a powerhouse in cable news".
O'Reilly added: "We're accumulating information and hopefully some day it will be clear ..."
Mediablast also noted that the four brothers who control Sinclair are tinkering with the idea of transforming WGN into a conservative all-news channel to compete with Fox News. "What they do.is come up with this scenario and try to reinforce that", he said. "He doesn't like the fact that Comey is unpredictable [and] ... that Comey would not aggressively investigate the leaks that have plagued the Trump administration", O'Reilly said. The messaging is always the problem ... "It's ramped up to a place where I think this is going to become a major story in the next six months". "There's this monolithic and very powerful industry that's developed to get Trump out of office", O'Reilly said. "This dishonesty in the media is harming this country".
