JFK's grandson rips 'Love Story' series about late uncle JFK Jr and Carolyn Bessette, calls it 'grotesque'

New York congressional candidate Jack Schlossberg criticized a Hulu and FX series about his uncle, John F. Kennedy Jr., and Carolyn Bessette's relationship in an interview on Sunday, calling the show a "grotesque" display of someone else's life and arguing it was fiction.

Schlossberg, the son of Caroline Kennedy and grandson of President John F. Kennedy, slammed "Love Story" as a way for the show's producer, Ryan Murphy, to make money. 

"Well, if you want to know someone who’s never met anyone in my family, knows nothing about us, talk to Ryan Murphy. I would just want people who do watch the show to watch it with one letter in mind, and that’s a capital F for fiction," Schlossberg told CBS News' Mo Rocca.

"The guy knows nothing about what he’s talking about, and he’s making a ton of money on a grotesque display of someone else’s life," Schlossberg continued. "I would hope that Mr. Murphy would donate some of the millions of dollars of profits that he’s making to maybe some of the causes that John championed throughout his life — justice, maybe he would donate some of that money to the JFK Library to help keep President Kennedy’s memory alive. But he’s not, he’s making money. This is not a documentary, and I’ll leave it at that."

Rocca noted there have been numerous movies and books about the Kennedy family and asked Schlossberg if there was something particular about "Love Story."

"I think in the last year, two years, three years, partly because of RFK Jr., but also partly because Donald Trump has used JFK as sort of a human punching bag, both by renaming the Kennedy Center after himself, by doing a false reinvestigation into the assassination, and dismantling all the programs that he fought for," Schlossberg said. "There’s a lot of misinformation now and iconography being used about the Kennedy family, my family, at a time when we really can’t afford to confuse people."

He encouraged Murphy to donate some of the money he's making off the series to something that helps get Trump out of office.

"We really need to take every breath that we have to try to make things better," Schlossberg said. "So, if Ryan Murphy really cares so much about the Kennedy family, my Uncle John, maybe he would try to do something about getting Trump out of power."

Hulu and FX did not immediately respond to a request for comment.

John F. Kennedy Jr. and Bessette died in a plane crash in 1999. Schlossberg is Kennedy Jr.'s nephew.

Executive producer Brad Simpson responded to Schlossberg’s initial criticisms of the series in February, insisting the show is a "sincere" reflection of his uncle’s life.

"What I hope is that when people watch the show, they will see our sincerity. They will see that we’ve approached this with love, and that we were trying to celebrate the life of Carolyn Bessette and JFK Jr.," Simpson told The Hollywood Reporter.

"I can understand why somebody could have a reaction before they see it, but I would say, ‘Watch the show,’ because I think they’re going to be surprised at how sincere it is," Simpson said.

Schlossberg was also confronted about some of his social media posts during the CBS interview on Sunday, specifically one targeting second lady Usha Vance. In one post, Schlossberg superimposed his face on one of Usha Vance's children.

He denied that he was "crossing a line" by involving the vice president's wife.

"I think what's crossing a line is the propaganda that we see issued every single day by the White House and Vance," Schlossberg replied. "So, what are we going to do, hold back? Hold back on our sense of humor and not tease them, make fun of them back?"

He added, "First of all, I don't think anyone was seriously thinking that I meant that we did actually have a love child! You can point at anything I posted, I will point you back at a president who shares pictures of himself bombing U.S. citizens with fecal matter. This is a new era we're living in."
