Eric Trump finally reveals what brother Barron really said to Joe Biden at inauguration after rumors he said ‘go f*** yourself’

Eric Trump has revealed what his younger brother Barron said to Joe Biden at Donald Trump's inauguration back in January.

The president's youngest son greeted Biden as his father was officially sworn in as the 47th President of the United States on January 20.

The 46th POTUS could be seen leaning in to shake Barron's hand while speaking to him. Barron appeared to greet the outgoing president and make a comment that left viewers absolutely hooked, as some suggested the 19-year-old told Biden to go ‘go f*** yourself’.

After taking a look at the viral clip, lip reader Jeremy Freeman revealed what Biden and Barron could have said to one another.

Freeman told LADbible that as Biden shook Barron's hand, he told him: "It's good to see you man."

According to Freeman, Barron then responded: "Exactly."

No one from the Trump family had commented on the exchange until now. Eric spoke on a recent episode of The Megyn Kelly Show about the viral moment and what exactly was said.

As per PEOPLE, Eric said: "Do you remember that whole controversy where [Barron] went up to Biden … and [the media] had all these like lip-reading experts [analyze it], and they’re like, ‘Barron just told Biden to go F himself’?

"So one night … I call Barron, I go, ‘Buddy, look, what did you actually say?’ And he goes, you know, like — it was something so polite I almost wouldn’t even get it right — but [something], like, ‘Congratulations and best of luck to you’ — or something like that."

Eric went on to say it was 'something very respectful' said between the pair, far from what was previously suggested by some people online.

Barron's older brother stated the youngest Trump 'doesn’t have that in him' to say such to an outgoing president.

Eric continued: "He’s a nice guy. He’s probably thinking it. He definitely has it up here, but like, he’s too courteous to actually go out there and say it. Barron’s a really nice kid."

An extended clip of the viral moment saw Barron move on to shaking Kamala Harris' hand after greeting Biden.

After viewers saw the new angle, Barron received praise for being a 'gentleman' and showing 'class' by shaking Harris' hand after she went up against his dad for the presidency.

"That's a bit of 'class' right there by Baron Trump," one viewer wrote, while another stated: "Direct eye contact and a handshake. A respectful thing. Young men don’t do this very often nowadays."
