FBI Director J. Edgar Hoover apparently was very distraught over the killing of Lee Harvey Oswald by Jack Ruby after the November 22, 1963, assassination of President John F. Kennedy, according to records released on Thursday by the National Archives in Washington, DC. Although President Donald Trump did not allow all of the National Archives' records on the assassination to be released, the records that have been released have proven to be quite compelling. The records portray a picture of a very enraged FBI Director Hoover who was desperate for a confession from Oswald so that he could say for certain that Oswald was the killer.

However, Hoover never was able to attain a confession because Oswald was killed before authorities could interview him and attain the confession.

Jack Ruby's role

Even after the release of the records from the National Archives, Jack Ruby's exact role in the assassination, if there was one, is still unknown. According to the Warren Commission, the official government panel that investigated the assassination and prepared a lengthy but much-contested report on it, Ruby was a businessman who was extremely upset over the assassination and decided to kill Oswald in the act of revenge.

However, many critics of the Warren Commission have claimed that Ruby somehow was connected to the assassination and killed Oswald to keep him quiet.

To many observers, this has sufficed as a plausible explanation for the events surrounding the shooting of Oswald; although it has been speculative only without proof. Others believe that Oswald may have been an agent for Fidel Castro, carrying out the assassination in retaliation for the Bay of Pigs fiasco. That is why Thursday's release of information by the National Archives was so critical to many of those who have been researching the assassination of President Kennedy for over five decades.

A great deal still is unknown about the killings of both Oswald and JFK. However, it is known that on November 24, 1963, just two days after the assassination of the President, that Oswald was being moved from one facility to another, more secure facility by the Dallas Police Department. As Oswald was being escorted through the basement, Ruby, posing as a reporter, walked right up to Oswald and shot him in the stomach.

Allegedly, in a desperate attempt to attain a confession from Oswald before he died, FBI agents were dispatched to the hospital. However, the effort was in vain because Oswald died before the confession could be attained. Hoover was exasperated because he could not claim to have solved the case.

Nikita Khrushchev was perplexed by JFK assassination

While Hoover was having to cope with not having solved the case, Nikita Khrushchev, the Soviet Premier at the time, was dealing with the loss of the American leader who he knew and trusted, President John F. Kennedy. To Khrushchev, Lyndon B. Johnson, (LBJ), Kennedy's Vice-President who succeeded to the office upon Kennedy's assassination, was a total enigma.

Khrushchev ordered Soviet agents stationed in the United States to gather information on Johnson and to report back to him. Khrushchev definitely would have preferred that Kennedy remained in office and was shocked to hear of his assassination, according to the newly released records.

One of the National Archives memos released on Thursday revealed that the Soviets believed that the assassination was the work of radical, right-wing, anti-Communist Americans. Allegedly the extremists hoped to propel anti-Communist sentiment by carrying out the assassination and then blaming it on Communist sympathizer Lee Harvey Oswald. Apparently, this is what the Soviets believed was the impetus behind the assassination; although there is no proof of such.

Trump and Ted Cruz's father

Much to the chagrin of Donald Trump, there was no proof of his allegations that the father of Senator Ted Cruz, (R-Texas), Rafael Cruz, was complicit in the assassination of President John F. Kennedy. During the GOP Presidential primary season, Trump had made wild-eyed claims that the elder Cruz had been present in Dallas on the day of Kennedy's assassination. Although he did not blatantly come out and accuse Rafael Cruz of having an active role in the noontime Presidential murder, he suggested that "somebody" should "look into the matter" to find out why Ted Cruz's father was in Dallas that day. Senator Cruz did not endorse Trump at the GOP Convention and did not speak to him for months afterward.
