One huge problem with Pres. Trump is his apparent inability to tell the truth. Bob Woodward’s book recounts the story that to prepare the President to be interviewed by Robert Mueller, his attorney staged a mock interview. John Dowd wanted to prepare his client, so he put together a mock interview. The President could not get through without telling some obvious lies, according to the book. Mr. Dowd was quite frustrated. Not the least because as a lawyer, his license is at risk if he allows a client to testify about lies. It violates ethical rules in every state for a lawyer to knowingly allow a client to tell a falsehood.
Andrew Hall discusses this dilemma regarding Mr. Dowd. Andrew Hall once represented John Erlichman, the former Watergate defendant. As Hall points out, any attorney who represents the President knowing he will lie or might lie puts his license at risk. See The Hill report here. That risk may explain why John Dowd resigned form the President’s defense last March. What many of us have forgotten is that after Watergate, many lawyers lost their licenses to practice law.
