Donald Trump supporters believe his biggest fan may be the son of another American president – however he died 19 years ago.

Conspiracy theorists are suggesting John F. Kennedy Jr - who passed away in 1999 in a plane crash – has been attending rallies to show his support for the current US leader and numerous videos floating around have pointed out why.

According to QAnon, JFK Jr could be alive and well if shots of a man going by the name of Vincent Fusca are anything to go by.

The theory might have a bit more gravitas if JFK Jr's body hadn't been recovered by Navy divers but people have been analyzing clips of the latest appearance of the JFK Jr lookalike for clues.

Trumps rally in Pennsylvania Wednesday made conspiracy theorists go wild about Fusca

Shots from the Pennsylvania rally Wednesday show Fusca sitting in the VIP seats and comments have claimed Trump waved in the direction of the man people think could be the son of former president John F. Kennedy and Jackie Onassis.

'I think I found DJT giving a salute back to the old guy who’s next to Fusca (light blue jacket). Am I crazy or am I crazy??' WWG1WGA tweeted.

People sharing footage online believe it could mean Trump and JFK Jr have been working together on his campaign.

In 1996 JFK Jr spoke about Trump running for the presidency one day.

'I think you should be asking those questions of Donald,' Kennedy said when asked if he'd following in his father's footsteps and campaign himself one day, the New York Post reported in 2016.

His comments came in 1996 when JFK Jr hosted his George magazine launch at Trump's Mar-a-Lago estate in Florida according to the late publisher's business partner at the time, Michael Berman.

'He'd clearly have the most extravagant winter White House,' the then-35-year-old editor-in-chief said.

Part of the theory is that JFK Jr's apparently faked death was part of an elaborate plan to seek revenge on the dark forces that killed his father in the 1963 assassination

Another element of the video that fans are going wild for is a handshake that takes place between Fusca and a man sitting next to him.

While the gesture isn't usually anything shout about when two men meet, some overly keen spectators have pointed out that the pair were spotted chatted before they touched palms, raising suspicions about whether they were putting on a show to divert attention.

'They both get on their cell phones almost at the same time & both cover their mouths almost at the same time as well & it looks like they say something to each other while they are on the phone,' WWG1WGA wrote on Twitter.

'This clip is interesting. The older man shows him something & he pushes his hand down as if he doesn't want anyone to see what he showed him. Very interesting.'

Fusca however is well aware all eyes are on him with a select group of Trump supporters who are convincing each other the Democratic 35th President's son would have wanted him in the powerful position.

The theory is not entirely new as Fusca told the Washington Post in August that he was vaguely aware of buzz he was creating.

The recognizable Trump supporter hasn't exactly denied being the late journalist-and-lawyer so it hadn't stopped the Internet and enthusiastic Republicans having fun with it.

RT findtruthQ: 1) More from the Erie Rally tonight and Vincent Fusca. I clipped some interactions he had w/ an older gentleman who sat next to him. Lets discuss these 3 clips. Will post youtube link in slide 4.



1st clip - hand shake. This is a handshake… https://t.co/77TijDNmLC — Truth and Conspiracy (@Seb_Aguanno) October 11, 2018

Videos are being scrutinized obsessively in an attempt to prove their claims correct

QAnon has been ramping up the theories since Trump has gotten back on the campaign trail

JFK Jr would be turning 58 on November 25.

With Fusca also creating a Trump Mobile that goes around to the country promote the 'Make America great again' slogan-user, it doesn't help quash the far-fetched rumors that JFK Jr faked his own death as part of a plan to get Trump into the White House.

At past rallies, people have even shared comparisons of a woman who smiles like JFK Jr's late wife Carolyn. Carolyn passed away in the same crash.

Part of the theory is that JFK Jr's apparently faked death was part of an elaborate plan to seek revenge on the dark forces that killed his father in the 1963 assassination. By going by a new identity, he would be able to avoid the same fate and infiltrate the system to return America to its former glory, over-the-top theorists say.

People enthralled by the conspiracy suggested a persona going by the name R was alluding to that in a post and that he may have taken on the name QAnon too.

The June post reads: 'In 1909, we lost everything.

'My father caught on.

'1st to the Bilderbergs, then he caught on the NASA.

'He demanded to know who the grey's were and why they were here.

'They killed him.

'I strategically staged my own death, allied with the one person in this world whom I knew was honorable enough to trust, and we began to build "The Plan."

'Penance is coming.'

Prior to the Trump theories that have also included speculation people are trying to take down the businessman-turned-politician from the inside, QAnon spent a lot of time doing what they believed was unearthing pedophile rings.
