A trove of more than 10,000 documents about the assassination of former U.S. Sen. Robert Kennedy has begun to be released, Tulsi Gabbard announced Friday.

Gabbard, President Donald Trump’s director of national intelligence, told Fox News she has concluded that the withholding of the files from the public is no longer a matter of national security. It’s also fulfilling a longtime promise by Trump to release all information about a murder that shook America’s foundation and left an enduring legacy of conspiracy theories that have persisted for more than six decades.

“This came about because President Trump promised the American people that his administration would be one of maximum transparency, and one of the first things he did when he came back into the Oval Office was issue an executive order that said we need to release all of the documents that we have, unredacted, on the assassinations of President John F. Kennedy, Senator Robert F. Kennedy, and Martin Luther King, Jr.,” Gabbard told host Brian Kilmeade.

The release will build on an earlier one by the administration, containing unredacted notes from the CIA about the 1963 murder of JFK in Dallas, Texas. While much of the material information had also been known, readers drew renewed attention to specific portions, including allegations by a former CIA employee that the agency was behind the shooting and who, months later, was found dead.

“What we have just released here today is 10,000 pages that have been sitting in boxes within the National Archives that have never been digitized or viewed publicly before. These are documents related to the government’s investigation into the assassination. Documents related to discussions that were going on in other countries – State Department cables around the assassination,” she continued, “and a lot of the questions and theories that were being posted throughout this investigation that I think most people have never seen before.”

The documents released Friday include responses from Kennedy’s assistant attorney general to advocates seeking to strengthen U.S. protections against encroachments by the Communist Party, a broad concern during the nation’s Cold War with Russia. A cable by the U.S. Information Agency in the wake of the shooting cautioned messengers against using “extremist and intemperate statements” such as “a sick society” to discuss developments about the shooting.

“As in the death of John Kennedy, many in the world again will regard today’s tragic shooting in terms of a conspiracy. We cannot and should not be in a position of adding to, or assessing in any way, this kind of theorizing,” its author writes to other officials.

Other portions of the 10,000 documents contain a summation of the shooter, Sirhan Sirhan, by the U.S. Justice Department shortly after it occurred. In this estimation, Sirhan “had little association or communication with” other members of his family, and had become more withdrawn since being injured after falling off a horse in 1966.

RFK, who served as his brother’s U.S. attorney general before rising to the U.S. Senate, was killed by Sirhan in 1968 while seeking the Democratic Party’s nomination for president. Almost exactly two months earlier, MLK had been shot and killed under similar circumstances while standing on his balcony outside his second-floor room at the Lorraine Motel in Memphis, Tennessee.

The string of high-profile murders gripped the nation and fomented an underground series of theories about the U.S. government’s involvement. To this day, researchers continue to proclaim that the CIA or the Chicago mob, which infamously feuded with the Kennedys after working to help elect them, were involved.

President Trump’s relentless transparency has received bipartisan praise from sleuths who refuse to let the mysteries of all three men fade with history. Rep. Steve Cohen (D-TN), a progressive Democrat who has pushed for full disclosure of JFK’s murder, praised Trump’s initial release of new documents back in March.

“It’s too soon to know whether there’s much in the documents released today, but it is a good sign that some progress toward the goal of full disclosure is underway,” Cohen said, according to Fox News. “The assassinations of the 1960s need to be understood in their full historical context and the documents being released may help us get there,”
