The 2,891 documents withheld until Thursday have fueled more than 50 years of conspiracy theories. The files that were withheld in full were those deemed "not believed relevant", Judge John Tunheim of Minnesota told AP.
Cuban leader Fidel Castro informed American lawmakers that his country was not involved in the plot, when White House investigators visited the island in 1978.
The memo came from the then-deputy director of the FBI, James Angleton, to the then-director, J Edgar Hoover. He placed those files under a six-month review while letting 2,800 others come out, racing a deadline to honor a law mandating their release. If there's a secret that you still don't have access to, that's going to be on your mind because it's still this unresolved issue.
LBJ's theory: Everyone has their theories, including Johnson. The withholding could take place if the release would cause "identifiable harm to military defense, intelligence operations, law enforcement or conduct of foreign relations" and if the "identifiable harm is of such gravity that it outweighs the public interest in disclosure".
"Where he got this idea from I don't know", Helms said.
President Donald Trump said he would release "all" of the much-awaited records relating to former President John F. Kennedy's assassination, "other than the names and addresses of any mentioned person who is still living".
Secret Service agent Clint Hill ran from the car behind, leapt on the back of the limousine and shielded Mrs Kennedy as the car sped away to Parkland Memorial Hospital.
According to an intercepted phone call in Mexico City, Oswald was at the Soviet embassy there on 28 September 1963 and spoke with the consul, Valeriy Vladimirovich Kostikov.
"After the word of the President's death was received the reporter informed the Cambridge police of the anonymous call and the police informed MI5". The caller then hung up. In the JFK files matter, one White House official said, Trump wanted to make clear he wouldn't be bullied by the agencies. Bystanders were shocked and amazed as the passengers appeared to be John F Kennedy and his glamorous wife Jackie. They would get up to $100,000 for government officials and $57,500 for "department heads".
The government was required by Thursday to release the final batch of files related to Kennedy's assassination in Dallas on Nov. 22, 1963. That might have affected his feelings toward the president. "The risk would not have been worth it".
"I am ordering today that the veil finally be lifted" on the records, the memo said. After all, Oswald himself denied shooting the president and called himself a "patsy".
A note sent to FBI agents quote a source telling them "the president was actually assassinated by Dallas police officer TIPPIT".
But she admitted: "I understand perfectly well why the international community - historians, political scientists and many other people who have for many years tried to find out the truth - are so captivated by this topic". He was shot dead two days later by nightclub owner Jack Ruby. "Lot of it is extraneous entirely", Sessions said.
In doing so, Trump walked back his previous decision to allow redactions on documents that intelligence agencies claimed compromised national security.
The existence of the memo suggests that the FBI was at least considering the possibility that somebody in England knew about the assassination in advance.
Then, suddenly, the document cuts off.
