Who IS Jack Schlossberg? JFK's hunky, half-dressed grandson who has gone viral with his rabble-rousing rants and cartoonish accents

An unlikely online hero - and heir to America's most storied political dynasty - could be coming to Joe Biden's rescue by convincing his hordes of admirers to elect the president for a second term. 

Jack Schlossberg, JFK's hunky grandson and nephew to White House hopeful Robert J. Kennedy Jr., has accrued a hefty millennial following by flexing his muscles and political opinions on Instagram.

While JFK was known for his captivating public speeches, his 31-year-old descendant seems to be channeling his own variation of the Kennedy charisma through a medium fit for the modern age - TikTok-style comedy videos. 

In a closely-fought 2024 race for the White House where every vote counts, it could be his unusual, half-dressed viral videos that sway the uncertain and somewhat apathetic millennial vote in the Democrats' favor come November. 

The demographic will be key to securing a win for Biden in battleground states after thousands of young Americans pledged allegiance to the uncommitted vote in light of the president's handling of the Israel-Palestine conflict.

Known as jackuno online, the 31-year-old viral sensation is encouraging fans to vote for Biden

Known as jackuno online, Schlossberg conveys heavily-accented caricatures of voters from various parts of the United States who blast RFK Jr., 70, while encouraging listeners to vote for Biden. 

In one video, he calls RFK Jr. a 'pr***' - telling followers he is 'lying to us' about being an independent candidate and is actually allied with Donald Trump, while accusing him of being a 'Russian stooge on steroids.'

The videos have elicited a mix of thirst and praise from viewers. 'This man has a weird combination of the Kennedy, Bouvier, and Schlossberg genes that make him oddly resemble his late uncle, but he's also f***ing funny,' one user noted. 

Some fans pledged to 'vote for whoever he tells me to' while citing his 'stunning good looks and effortless charisma of one who kills without remorse' for winning them over. 

Others commented 'accent goes hard', 'preach', 'you need to understand that I'm single', 'Jack you slay, I'm voting for President Biden', and 'I LOVE YOU JACK SCHLOSSY'. 

Schlossberg's political standing echoes that of his wider family, who have endorsed Biden as the flagbearer to carry the Kennedy influence forward, in what is also a blow to RFK Jr.

'Nobody competes with President Biden when it comes to carrying on the legacies of John Kennedy and Robert Kennedy and Ted Kennedy,' RFK's daughter Kerry Kennedy told ABC's Good Morning America. 

Joseph Kennedy III even went as far at to tell NBC News that the candidacy of RFK Jr. 'poses a threat to the country that I love.' 

Dozens of the dynasty members joined Biden at the White House for St Patrick's Day in March, and RFK Jr. was a notable absence. 

RFK Jr. is the son of US attorney general and senator Robert F Kennedy, who is JFK's brother. 

Another sibling of the same generation, Eunice Kennedy Shriver, founded the Special Olympics and her daughter, Maria Shriver, married Arnold Schwarzenegger.

It's unclear what sparked Schlossberg's recent flurry of Instagram posts, which started with a video of him flexing his muscles and holding a one-legged yoga pose beside the ocean one week ago.

Since then, the Harvard and Yale graduate has posted several times daily to share more images of him showing off his impressive physique - and his political opinions - while accruing more than 120,000 followers. 

While impersonating a Massachusetts fan of the Kennedys called 'Jimmy' in one video, Schlossberg calls 'the new guy' RFK Jr. a 'freaking pr***' who is 'lying' to voters about being an independent candidate. 

'He's got Trump's donors, he's got Trump's advisors - him and Trump go way freaking back,' Schlossberg says while wearing a backward baseball cap. 'Don't be fooled by that, don't throw away your vote - vote for Biden, he'll be good.'

He also mimics a southern horse breeding character called Wade, saying: 'You can always tell when a horse has been pumped full of testosterone - steroids doesn't make the horse think any better'. 

Speaking as an Italian-American New Yorker character called Anthony, he conveys concerns that RFK Jr. would cut military funding just as hostile foreign powers like Russia are 'on our ass'. 

The internet star, whose full name is John Bouvier Kennedy Schlossberg, is the son of US Ambassador to Australia Caroline Kennedy and Ukrainian designer Edwin Schlossberg, with two older sisters, Tatiana and Rose. 

Schlossberg explained his new viral video process in an interview with the Boston Globe from Hawaii on Wednesday.

'A vote for Bobby Kennedy Jr. is a vote for Donald Trump, and I think that's a dangerous path for our country to take,' he said. 'All I'm trying to do is draw attention to what I think people should be focused on.'

The Yale and Harvard Law School graduate, 31, has collected thousands of Instagram followers, often showing off his incredible physique in an extremely revealing shirtless photos while enjoying a late-night workout at the gym 

However, he says there's no plan to try and make it to Saturday Night Live or a stand-up comedy club anytime soon.

'I can't sing, I can't dance, but I can do some accents,' Schlossberg said. 'I was using the tools at my disposal to talk about something I really care about. That people find it funny or that it breaks through I think is awesome, but there is no master plan.' 

Schlossberg's career path has been varied - including a cameo appearance as a police officer in CBS crime drama Blue Bloods when he was 25 - and a staff assistant role in an environmental section of the US Department of State. 

After graduating from Harvard Law in 2022, he passed the New York State bar exam in April 2023, which is the next step to becoming an attorney. 

Schlossberg previously said Biden was on the way to becoming the country's 'greatest progressive president we've ever had.'

He also called anti-vaxxer RFK Jr.'s candidacy an 'embarrassment,' and said that if he cared about his family's legacy he'd support the current occupant of the Oval Office.

'Instead, he's trading in on Camelot, celebrity, conspiracy theories and conflict for personal gain and fame,' he added. 

'I've listened to him. I know him. I have no idea why anyone thinks he should be president. What I do know is his candidacy is an embarrassment. Let's not be distracted again, by somebody's vanity project.'

He also appeared on the Today program alongside his mother to defend waging the inter-family war for online views. 

'I stand by what I said in the video,' he said, referring to a clip where he accuses RFK Jr. of abusing the family name for his own political gain. 

'I love my family and I'm very proud of our legacy of public service… but I think Joe Biden is a fantastic president,' Schlossberg added. 

Using a heavy Boston accent and going under the name 'Jimmy' he referred to RFK Jr. as 'a friggin' prick' and that 'he goes way freakin' back' with former President Donald Trump

His mother denied that family relations must be strained. 'It's not complicated,' she said.  

RFK Jr. has been gaining traction as a more realistic candidate in recent weeks, with polls indicating that voters who are tired of the two-party system and another match-up between Biden and Trump could turn to him instead. 

Kennedy receives enough support among the electorate that he could even sway the outcome of the 2024 election, according to an April NBC survey. 

In a head-to-head matchup, Trump is two points ahead of Biden, 46 percent to 44 percent. But when Kennedy Jr. on the ballot, Biden shifts ahead of Trump by two points, Biden with 39 percent and Trump with 37 percent. 

Pollsters showed that Trump voters were more likely to choose Kennedy, when given the chance to choose from potential third-party candidates.
