Former US president John F. Kennedy's assassination was the first in a string of politically motivated killings, including those of his brother Robert F. Kennedy, that stunned the United States during the turbulent 1960s.
President Donald Trump on Thursday ordered the release of 2,800 documents related to the 1963 assassination of President John F. Kennedy but yielded to pressure from the FBI and CIA to block the release of some information, senior administration officials said.
Congress had ordered in 1992 that all records relating to the investigation into Kennedy's death should be open to the public, and set a final deadline of October 26, 2017, for the entire set to be made public.
Trump had confirmed on Saturday that he would allow the documents to be made public.
Administration officials told reporters on a conference call that Trump ordered government agencies to study the redactions in the documents over the next 180 days to determine whether they needed to remain hidden from the public. After the review, Trump expected such withholdings to be rare.
The officials described Trump as reluctant to accept agency requests to hold back thousands of documents but felt in the end he had no choice but to agree to their entreaties.
"The president wants to ensure there is full transparency here and is expecting that the agencies do a better job in reducing any conflicts within the redactions and get this information out as quickly as possible," one official said.
Another official said: “There does remain sensitive information in the records” that could compromise the identity of informants or intelligence operations.
Academics who have studied Kennedy's slaying on November 22, 1963, during a motorcade in Dallas said they expected the final batch of files to offer no major new details on why Lee Harvey Oswald gunned down the Democratic president.
They also feared that the final batch of more than 5 million total pages on the Kennedy assassination held in the National Archives would do little to quell long-held conspiracy theories that the 46-year-old president's killing was organised by the Mafia, by Cuba, or a cabal of rogue agents.
