Bizarre Trump 'body double' conspiracy theory sparked as people spot specific detail following World Cup appearance

Comedian Jon Stewart joked over a bizarre Donald Trump 'body double' conspiracy theory after people spotted one specific detail during his World Cup appearance.

In one clip which has since gone viral online, the 80-year-old Republican could be seen at the World Cup final on Sunday (19 July) following Spain's 1-0 win against Argentina.

The clip in question, shared by the White House's Rapid Response account on X, showed Trump standing next to Spain star Rodrigo Hernández Cascante, known as Rodri, who looked noticeably taller than him - despite the fact that both men are reportedly the same height.

ESPN reports that Rodri, 30, is 6 feet 3 inches tall while Trump's official physical examination from April 2025, conducted by White House physician Dr Sean Barbabella, also listed the president at 6 feet 3 inches tall.

"Spain captain Rodrigo Hernández Cascante is listed at 6' 3". So is Trump. He's gonna strain his neck looking up at Rodri!" quipped one X user.

A second chimed in: "Well it's pretty obvious all the nonsense about his height isn't true."

A third slammed: "Rodri is ACTUALLY 6’3”."

"5’11" (at best)," chirped a fourth.

Amidst the debate about the president's height, Trump's appearance following the World Cup final also sparked a bizarre 'body double' conspiracy.

Referring to a video of Trump after landing at Joint Base Andrews in Maryland after the FIFA World Cup final, comedian Jon Stewart pointed out a man who could be seen walking behind the president in the background.

"What's up with the guy behind Trump? Can we see that again?" he asked on Comedy Central's The Daily Show.

The man in the clip was seen donning a suit in the same colour as Trump's with a different coloured tie, and the pair had a similar build and stature.

"Who the ... is this guy? Who in the world is this? Oh my god, is that a back-up Trump?" Stewart joked. "Wait a minute, hold on a second! Wait, what? Is that a back-up Trump, or is that Trump? Wait, is the one we've been dealing with backup Trump? Or is that Trump?"

While Stewart's joke was a bit of light-hearted fun, the White House has issued a blistering response.

Spokesperson Davis Ingle told Tyla: “Jon Stewart is a talentless hack who clearly suffers from a severe and debilitating disease known as Trump Derangement Syndrome that has rotted his peanut-sized brain and ruined his life to the point he has to compensate for his embarrassing inadequacies.”
