NIxon's 6/23/72 and Trump's 5/10/17 Conversations

Here is an excerpt from a New York Times article I just read:

“I just fired the head of the F.B.I. He was crazy, a real nut job,” Mr. Trump said, according to the document, which was read to The New York Times by an American official. “I faced great pressure because of Russia. That’s taken off."

This was the quote attributed to our president by an official in the room during the May 10th meeting with the Russian ambassador, regarding the sacking of FBI Director James Comey the day before.  It essentially reveals the president of the United States manipulating the FBI to lay off an investigation that could implicate his administration or even himself.  Now let's go back some 45 years to June 23rd, 1972.  The Watergate Hotel break-in had just occurred the week before and then-President Nixon was conferring with his Chief of Staff Bob Haldeman.  According to the taped conversation, later known as the "Smoking Gun" and ordered turned over by unanimous vote of the U.S. Supreme Court on July 24th, 1974, this is what ensued...the context is revealed earlier in the recorded dialogue to be about the FBI investigation of the Watergate burglary, committed in large part by anti-Castro Cuban émigrés...and the administration's efforts to get the CIA to exert influence on the FBI to stop it:

Nixon:  When you get in these people when you…get these people in, say: “Look, the problem is that this will open the whole, the whole Bay of Pigs thing, and the President just feels that” ah, without going into the details… don’t, don’t lie to them to the extent to say there is no involvement, but just say this is sort of a comedy of errors, bizarre, without getting into it, “the President believes that it is going to open the whole Bay of Pigs thing up again. And, ah because these people are plugging for, for keeps and that they should call the FBI in and say that we wish for the country, don’t go any further into this case”, period!
Haldeman:  OK.
Nixon:  That’s the way to put it, do it straight (Unintelligible)
Haldeman:  Get more done for our cause by the opposition than by us at this point.
Nixon:  You think so?
Haldeman:  I think so, yeah.

This last conversation ended the presidency of Richard Nixon.  Upon hearing the tape the eleven Republican representatives on the House Judiciary Committee who had voted against his impeachment immediately declared that they were now in favor of it.  And Senator Barry Goldwater himself personally notified the president that it was all over.  That was in August of 1974.  Now it is June of 2017 and we have a record of the current president interfering in the FBI's investigation of his campaign regarding its possible connections to Russian interference in the 2016 election.  But Donald Trump isn't being caught by a secret tape recording his words: he openly boasts about what he has done...and why!  And yet not a single Republican senator or representative seems the slightest bit concerned that he has done anything wrong...and this time around, it is they...not the Democrats...who control Congress...
