Query: Lied about Eisenhower

Its sad when you go out and buy a book about history. You spend a couple weeks reading the book. Then you love it. You even feel bit more educated about something you are passionate about. But if you realize that the person who wrote it just might have decided to make up whatever details suited him to tell his story. And then you know he's been known to do such a thing on other works. Then he's a proven liar who build his whole career out of pretending to be best buddies and biographer to Dwight Eisenhower. Nothing Ambrose wrote can be accepted as truthful. The publishers should warn people.
