Bush Sr was so important in 1963 (despite being officially just an oilman and a Senate candidate from Texas) that J. Edgar Hoover as head of the FBI sent Bush a memo right after JFK was killed briefing him about the effect this assassination was having on Cuban exiles. The CIA essentially claimed years later that it wasn't the same George Bush, but never offered an explanation of who this other George Bush was who was so important that Hoover would be briefing him on the developments.
So Bush was unofficially in the CIA in 1963 heading up field operations related to Cuba, but officially he was running Zapata Oil and he was running for the open US Senate seat in Texas. And yet years later when Kitty Kelly was interviewing him for his biography and she asked where he was when he first heard about the JFK Assassination, he said he didn't recall. Everybody alive when JFK was killed remembers exactly where they were when they heard the news, just like people who were alive on 9/11 remember it clear as day what they were doing when they saw the towers fall. And yet here is a guy doing work for the CIA which was very much in opposition to what Kennedy wanted done in Cuba, and who was running for US Senate and yet when JFK was killed he doesn't really remember it well enough to know what he was doing at the time.
Well thanks to the Kitchel memo[1], we now know that Bush Sr. was staying in the Dallas Sheraton Hotel, a block away from where JFK was killed, and checked out after the assassination.
Also in that memo it shows that he effectively called in a false flag on some other guy named James Parrot[1], for unknown reasons. It could be argued that it helped distract the Secret Service away from Oswald, who was already being at least passively surveilled due to his prior known associations regarding Cuba and political "activism" in general.
This is a lot of circumstantial evidence that is hard to explain away with a different explanation. As to why Trump wouldn't expose any of this information, that would assume Trump was more than just a conman grifter who tricked his way into the White House. Of that, I have not seen enough evidence.

Barbara Bush said in her memoirs that he was in Texas, near Dallas, at that time.
Trump, for all the things he did that were "rebellious", was in lock-step with the deep state for not releasing all of the files. I'd like to see the discussion Trump had with the Archives custodian's or whomever has the power to release or not allow the release of such things.
Trump was smart to have his own private security detail.
In the absence of the truth, there will ever only be theories.
JFK very much disliked how the CIA had it's own secret wars and operations without presidential approval or even knowledge of their existence. Trump, for all the things he did that were "rebellious", was smart to have his own private security detail.
JFK's assassination was the original fake news.
I hate nobody, but I am bothered greatly by those who seek to weaken their own country by selling its secrets to others — for their own personal profit.
That Trump and members of his administration remain free, despite openly doing just that on numerous occasions, would seem to undermine your belief that the DOJ did anything other than ask Trump “how high?”.
So, Correction: no, they did not :)
