Former Fox News host and serial sexual harasser Bill O’Reilly is writing a “history book” about President Donald Trump, and he spent part of his weekend in the West Wing and on Air Force One with exclusive access to the president.

O’Reilly left Fox News in 2017 after a cascade of reports and legal settlements alleging he had been serially sexually harassing co-workers and guests for more than a decade.

On February 4, O’Reilly tweeted a photo posing next to Air Force One, cryptically captioned with just an American flag emoji. Later that night, he tweeted that he had “an upcoming book on President Trump.”

On his subscription-based online platform, O’Reilly told viewers he is writing a new book about Trump (not part of his Killing historical book series) and that he had off-the-record conversations with administration officials in the West Wing before boarding Air Force One over the weekend. On Air Force One, O’Reilly claims he had exclusive access to Trump and asked “some pretty intense questions” that the president compared to torture:

BILL O’REILLY: OK, let me tell you about the book. So Friday, I go to Washington and it's always a privilege to go to the White House. I'm in the West Wing talking to a bunch people. I'll never tell you what I say because that's off the record, but I know a lot of people in the Trump administration for a long time, and I learned a lot, which is why I can report accurately to you every day.

So then I go to Andrews Air Force Base, this humongous Air Force One. I had never been on it. It’s the biggest machine I've ever seen. There I am. It's a little chilly but, you know, I can take that. And so I go on a plane and I interview Donald Trump, the president of the United States, on the plane. There I am.

So the interview is for a book that I am writing on Mr. Trump. It is a history book. I want everybody to know that, not part of the Killing series. It's a history book on Donald Trump. Why he believes what he believes -- fascinating to me. I've known the guy 30, 35 years. Tough to get him to talk about his childhood, his parents, his brothers and sisters. That's what the book's about, and it's about what I've seen, personally, over those 30 years with him.

Now I'm not his buddy. In fact, he got mad at me during the interview. He goes, “You're torturing me.” I was -- I wasn't torturing. But I was asking some pretty intense questions. I didn’t think it was torture -- I go right up to the torture line. He thought I was doing a CIA number on him. But I got what I had to get to write the book.

Now I'm not sure when the book's going to be out. I’ve already written the first chapter of the book, but I'm not sure. But we'll keep you posted on that. But I've got to tell you, it was it was such an honor for me to fly on Air Force One, to see all this up close -- how our country is run. And it was really, it's really interesting. And I'll make one pledge: I will tell you the absolute truth in this book. This is a history book. It's not pro-Trump, it's not anti-Trump. It's history.

In April 2017, The New York Times first broke the news of O’Reilly’s sexual harassment settlements, spurring public pressure until he was fired from Fox News weeks later. Later reporting revealed that Fox and O’Reilly actually paid out a total of about $45 million in six publicly known settlements with women reporting he sexually harassed or verbally abused them -- including one previously unknown $32 million sexual harassment settlement reached shortly before Fox renewed his contract in early 2017.

Shortly after O’Reilly’s firing, Fox News Co-president Bill Shine also left the network after being repeatedly implicated in Fox News’ toxic culture of sexual harassment and misconduct. Shine was known as former Fox chief Roger Ailes’ right-hand man, and he reportedly retaliated against and attempted to silence those who came forward to report harassment by Ailes. Shine also led Fox as it paid out millions of dollars in settlements to O’Reilly’s numerous accusers.

Shine now works in the Trump White House overseeing communications strategy, which might include, for example, arranging a meeting between one sexual predator occupying arguably the most powerful office in the world and another who is perhaps hoping to reestablish his own career with an exclusive interview on Air Force One.
