JFK's grandson slams Donald Trump in scathing message following release of declassified files

Despite being given a substantial heads-up, it seems Jack Schlossberg was hurt by the public release of his grandfather John F Kennedy's assassination files.

US President Donald Trump has been promising to declassify tens of thousands of secret papers since he first term in the White House, and the moment finally arrived on Tuesday (18 March).

JFK, the US' 35th president, was assassinated by Lee Harvey Oswald in 1963 while on a presidential motorcade in Dallas, Texas.

His death triggered many conspiracy theories in the decades to follow, which is why the release of the assassination files this week has been such a huge talking point around the world - but Schlossberg isn't happy about it.

Now working as a political correspondent for Vogue magazine, Schlossberg - whose mother is the only surviving child of JFK and former First Lady Jacqueline Kennedy - royally kicked off on social media once the documents were released.

But maybe he's yet to realise that they barely provide any earth-shaking information?

He wrote via the site formerly known as Twitter on Wednesday (19 March): "No — THE TRUMP ADMINISTRATION DID NOT GIVE ANYONE IN PRESIDENT KENNEDY’S FAMILY 'A HEADS UP' ABOUT THE RELEASE. a total surprise, and not shocker!!

"But @RobertKennedyJr definitely knew."

Schlossberg was, of course, referring to JFK's son here, whose mother Ethel Kennedy sadly passed away just five months ago.

Many social media users took umbrage with the journalist's apparent frustration though, highlighting the fact the family knew this day would eventually come.

"I mean, they've only been saying it for how long now? If you didn't know it was coming then that's on you," read one of the strong reactions.

"He's been talking about it for ten years Jack," was another point.

A third person went on to ask: "He's been saying he was going to release those files for years. how you could not possibly know seems like a lie. or maybe you thought he was joking and would never do it. but how did I know it was coming yet you, a Kennedy, didn't."

This didn't stop Schlossberg from reinforcing his annoyance on Instagram a little bit later on.

Directing his phone camera towards an on-screen CNN broadcast, which was covering the declassification story, he said: "You're better than this. This is so f**king stupid, there's so much actual news going on, why are you covering this?

"At least report that something happened, why are you guys covering this? Stop. This is why this s**t takes hold, because you guys f**king cover it over and over and over again."
