Cutting a deal with prosecutors by offering information on a former boss or superior "almost ought to be illegal," President Donald Trump said Wednesday, one day after his former attorney implicated him during a guilty plea in federal court.

"This whole thing about flipping, they call it, I know all about flipping. Thirty, 40 years, I have been watching flippers. Everything is wonderful and then they get 10 years in jail and they flip on whoever the next highest one is, or as high as you can go. It almost ought to be outlawed," Trump said in an interview that was taped Wednesday and aired Thursday morning. "It's not fair."
