Trump would be a very difficult client for any lawyer. He turned the drafting of his first immigration order to Steve Bannon and Steve Miller-- who are not lawyers but who talk and think like Trump so they produced something Trump liked, but it was never fully reviewed or changed by the lawyers before it went out and it was a mess from a legal standpoint-- and Sally Yates would not defend it and got fired as a result. As George Conway points out, Trump does not listen to lawyers when they tell him not to tweet.
