The National Archives released more than 13,000 documents related to the assassination of President John F. Kennedy Thursday, while President Biden ordered thousands of other records kept under wraps until at least the middle of next year.

The trove of documents were made public after Biden issued an executive order authorizing their release.

“This significant disclosure reflects my Administration’s commitment to transparency and will provide the American public with greater insight and understanding of the Government’s investigation into this tragic event in American history,” Biden wrote in his order. 

An initial review by The Post found few new revelations about the events of Nov. 22, 1963, when Kennedy was shot while riding in a motorcade in downtown Dallas. 

One document appeared to shed light on how the CIA intercepted assassin Lee Harvey Oswald’s communications with the Soviet Embassy in Mexico City a few weeks before the murder. 

The previously redacted agency document shows that a wiretap operation targeting the embassy was done with the help of the office of the Mexican president, but without the knowledge of Mexico’s internal security or law enforcement officials.

In that call, recorded Oct. 1, 1963, Oswald asked an embassy guard if there was “anything new” about a telegram a Soviet diplomat had promised to send to Washington on Oswald’s behalf. The guard answered that “the message had gone out but no answer had been received.”

A report on the call was sent to the FBI, State Department and Navy Department.

“At this writing (13 December 1963) we do not know what action the FBI and other agencies may have taken based on our report,” the CIA report said.

Another CIA report from September 1964 described an intimate lunch between American and Soviet officials in Helsinki. At the meal, Felix Karasev, a KGB general, stated that he thought Jack Ruby — the Dallas nightclub owner who shot and killed Oswald two days after the Kennedy assassination — was a “tool of ‘reactionary forces’” and that he had help from “some US officials.”

“We tried [to] debunk this impression, but Karasev held to his views,” the document read. 

Earlier in the conversation, the Americans questioned “what really happened to Oswald during his stay in the USSR” after he defected in 1959.

“Karasev caught the implication,” the report read, “and replied that this would have been possible if Oswald had been in China but not in the Soviet Union.”

In total, 13,173 new files were made public Thursday, the largest release of JFK assassination material since 2018. Approximately 4,400 documents are still being withheld “to protect against an identifiable harm to the military defense, intelligence operations, law enforcement, or the conduct of foreign relations that is of such gravity that it outweighs the public interest in disclosure,” the White House said.

More than 3,000 other documents are being withheld in full or in part because they were under seal, were part of grand jury proceedings, or involve individuals’ tax information or details of gifts or donations to the US government. Those documents cannot be released independently by the Archives, the White House, or the executive branch.

One document appeared to shed light on how the CIA intercepted assassin Lee Harvey Oswald’s communications with the Soviet Embassy in Mexico City a few weeks before he shot Kennedy in Dallas, Texas.

The previously redacted document shows that a wiretap operation targeting the embassy was done with the help of the office of the Mexican president, but without the knowledge of Mexico’s security or law enforcement officials.

Biden’s order set a new deadline of May 1 for the National Archives and other agencies to review the remaining redacted documents and propose keeping any material under wraps beyond June 30, 2023. 

The 1992 law required the government to release all non-exempt documents related to the 35th president’s murder by October 2017. 

Former President Donald Trump released some 2,800 secret records in 2017, and the Biden administration ordered the release of nearly 1,500 more records last year.

Kennedy became the fourth US president to have been assassinated while in office when Oswald fired at his motorcade from the 6th floor of the Texas School Book Depository in downtown Dallas on Nov. 22, 1963.
