John W. Dean, age 80, who was fired as White House counsel by President Nixon, writes for the N.Y. Times:
What's new: "There are several parallels between my testimony before Congress in 1973, about President Richard Nixon and his White House, and Michael Cohen’s testimony this week about President Trump and his business practices. ... [W]e both found ourselves speaking before Congress, in multiple open and closed venues, about criminal conduct of a sitting president."
