"The President then asked, “What about these notes? Why do you take notes? Lawyers don’t take notes. I never had a lawyer who took notes.” McGahn responded that he keeps notes because he is a 'real lawyer' and explained that notes create a record and are not a bad thing, that it’s his legal responsibility to keep an accurate record of events. The President said, “I’ve had a lot of great lawyers, like Roy Cohn. He did not take notes.”
