The government has withheld roughly three thousand pages of documents surrounding JFK’s death from the public for decades, even as some details surrounding the assassination that occurred over 60 years remain disputed, sparking speculation, including from other members of the Kennedy family, as to what happened on Nov. 22, 1963. 

However, Schlossberg was not among the family members who were happy about Trump’s move to declassify the controversial materials Thursday. Instead, he took to social media to air grievances against the new president, accusing Trump of “using JFK as a political prop, when he’s not here to punch back.” 

“There’s nothing heroic about it,” Schlossberg said in a post to X. 

He also suggested he was already briefed on the files, telling one X user, “I know everything…”

Schlossberg further indicated that the documents held no great surprises about the nature of his grandfather’s assassination. 

“JFK conspiracy theories — The truth is alot sadder than the myth — a tragedy that didn’t need to happen. Not part of an inevitable grand scheme,” he said. 

Even before the classified files debate, Schlossberg was no fan of Trump. A firm Democrat, he spoke out in support of the president’s one-time arch nemesis, former Vice President Kamala Harris, during a speech at the Democratic National Convention in August 2024. 

In contrast to Schlossberg, others in the Kennedy family have emerged as fierce proponents of efforts to uncover more details about JFK’s death. 

Robert F. Kennedy Jr., Trump’s nominee for secretary of Health and Human Services, praised the president’s executive order declassifying the Kennedy assassination files Thursday. 

“I think it’s a great move because they need to have more transparency in our government, and he’s keeping his promise to have the government tell the truth to the American people about everything,” RFK Jr. told reporters. 

After Trump signed the executive order releasing the files, he handed the pen used to an aide and directed it to be given to RFK Jr.

The HHS nominee’s celebration came after he had long raised concerns that the CIA was involved in his uncle’s murder due to his stance on the Vietnam War. 

“There is overwhelming evidence that the CIA was involved in his murder,” RFK Jr. said during a 2023 interview with radio talk show host John Catsimatidis. “I think it’s beyond a reasonable doubt at this point.”

“When my uncle was president, he was surrounded by a military-industrial complex and intelligence apparatus that was constantly trying to get him to go to war in Laos, Vietnam, etc.,” he continued. “He refused. He said that the job of the American presidency is to keep the nation out of war.”

In a video posted to Instagram on Friday, Schlossberg blasted his cousin for suggesting JFK’s murder was connected to the CIA during an appearance on the Joe Rogan Experience.

“Now, since Trump did the declassification, and RFK Jr. can’t hide behind that anymore, I think you should have him back on your show and ask him why he lied to everybody about how the CIA killed President Kennedy, and ask him if he went through all the documents,” Schlossberg said.

After the files were released, some experts suggested they could prove “embarrassing” to the CIA.

“I think that we could actually find the files that are very embarrassing to the CIA and one of the reasons they’ve held on to these for so long,” said Gerald Posner, the author of Case Closed: Lee Harvey Oswald and the Assassination of JFK.

There are still approximately 500 documents related to JFK’s assassination that experts believe Trump will not be able to release, according to an Associated Press analysis. 

On Thursday, Trump also signed executive orders releasing classified materials surrounding the assassination of Martin Luther King Jr. and Robert F. Kennedy, who was killed in Los Angeles during his 1968 Democratic presidential campaign.
