In an attempt to quell the outrage surrounding his presidency's involvement with the scandal, Nixon spoke before the Associated Press Managing Editors annual conference, and it was actually during a Q&A portion of the speech where he blurted out the words that would ultimately define his legacy.
"I made my mistakes, but in all of my years of public life, I have never profited, never profited from public service — I earned every cent,” he said. “And in all of my years of public life, I have never obstructed justice. And I think, too, that I could say that in my years of public life, that I welcome this kind of examination, because people have got to know whether or not their president is a crook. Well, I am not a crook. I have earned everything I have got."
The next day, in the Nov. 18 edition of the New York Times, the paper concluded that the president did a nice job acquitting himself: "The president seemed composed and on top of the subject throughout the session, faltering perceptibly only during the discussion of his taxes. In contrast with some of his recent appearances he did not berate his critics or his political enemies."
It's pretty easy to make the "obstruction of justice" connection to the current presidency. So, perhaps "Wouldn't it be great if we got along with Russia," will define the Trump presidency.
Or maybe just "Grab 'em by the pussy."
It's hard to choose.
