Sportswriter Rick Reilly, the author of the new book, "Commander in Cheat: How Golf Explains Trump," speaks to CNN's John Berman about how the president's tendency to cheat at golf explains his personality.
"He cheats like a mafia accountant. He cheats crazy. He cheats whether you’re watching or not. He cheats whether you like it or not," Reilly said.
"He kicks the ball out of the rough so many times the caddies call him Pele," he also said.
