J.F.K.’s Grandson Slams File Release, and the News Media’s Reaction

Mr. Schlossberg, 32, the son of the president’s daughter, Caroline Kennedy, and an outspoken voice in Democratic politics, has long been a critic of the Trump administration and its policies. During last year’s election cycle, he made a series of comedic TikTok posts that mocked Republican candidates, as well as his cousin Robert Kennedy Jr., who was then running for president as an independent. But the unsealing of 64,000 pages of files about his grandfather’s assassination, under an executive order from President Trump, made the political personal.

In a series of posts on X that were fiery even by Mr. Schlossberg’s standards, he said that the Trump administration did not give anyone in President Kennedy’s family a “heads up” before the documents were released. “A total surprise, and not shocker!!” he wrote.

The Trump administration did not immediately reply to a request for comment about Mr. Schlossberg’s assertion that the Kennedys had not been advised on the release ahead of time.
