In a lengthy conversation with host Sean Hannity on Tuesday, the two hosts discussed at length their opinions on the news of the day, criticizing the media and NFL players protesting police brutality and racial injustice by kneeling during the national anthem.
Though the two largely avoided the subject of O'Reilly's departure, the former host lamented the advertising boycott that helped push him out.
"I didn't, and I should have." O'Reilly also singled out Media Matters, one of the left-leaning watchdog groups that pressured advertisers to abandon both programs earlier this year.
In an interview on Hannity's radio show earlier this month, O'Reilly said he was focusing his efforts on a potential legal battle and investigation to clear his name, referring to some claims of sexual harassment against him as a "kind of defamation," though he hasn't offered many specifics.
In promoting his new book, the former host has sat for interviews with Breitbart News, The Hollywood Reporter, and NBC's "Today" show, where he clashed with host Matt Lauer, who pushed back on O'Reilly's claim that the revelations of sexual-harassment allegations against him were a "hit job." Despite reports that some employees at Fox News are not happy with the ousted host's informal return to the network, Tuesday's interview likely won't be O'Reilly's last on Fox.
