Former Fox News host Bill O’Reilly is writing a different kind of book about “the man” Donald Trump, not the president or businessman.

“It’s a big history book on the man. Not on security, economy and politics — which is what he really wanted to talk about. This is on him. Alone. The man. The human being. What he believes. His history. Background. Family. School. Friends. Thoughts. Growing up,” O’Reilly said, according to Page Six.
