'Third grade stuff': President Trump roasted over 'unfathomable' Super Bowl gaffe

Donald Trump is no stranger to slips of the tongue, but the American president may have outdone even himself with an embarrassing Super Bowl blunder.

Moments after the Kansas City Chiefs were crowned Super Bowl champions after defeating the San Francisco 49ers, the American leader decided to tweet his congratulations.

‘SHOULD BE BANNED’: Fan caught napping in $5000 blunder

The only problem was, he was let down by an inexplicable lack of knowledge about the country in which he was elected leader.

To be fair, he was also let down by the fact that no one appears to proof read his tweets before they're sent out.

President Trump's problem stemmed from the fact that the Kansas City Chiefs play out of the state of Missouri.

Someone obviously forgot to tell him that, however, before he paid tribute to the team's comeback victory in the NFL decider.

In a since-deleted post, Mr Trump commended the Chiefs for representing the "Great State of Kansas" so well.

The president was roasted over the mistake on social media, with many users joking that he'll have state boundaries changed so his Tweet is actually right.

Chiefs seal comeback win in controversial circumstances

After trailing 20-10 in the fourth quarter of the Super Bowl, the Kansas City Chiefs took a stunning late lead over the San Francisco 49ers thanks to a touchdown catch and run by running back Damien Williams.

But should it have counted?

With Kansas City trailing 20-17 with 2:44 left in the fourth quarter, Williams took a swing pass from Patrick Mahomes on third-and-goal from the five-yard line and ran to the corner of the end zone.

Williams reached the ball over the right pylon as he was pushed out of bounds.

Officials ruled it a go-ahead touchdown.

They took a long look at the play via replay review to determine if Williams actually scored.

Replays showed a close play as Williams stepped out of bounds around the same time the ball crossed the plane.

But none of the angles showed anything conclusive. Officials ruled that the call on the field stood, granting the Chiefs a touchdown as they took a 24-20 lead.

Had officials not ruled it a touchdown on the field, it seems likely that call would have stood as well.

Replay wasn’t clear, and the biggest call in the Super Bowl swung in the Chiefs’ favour.

Chiefs champions for first time in 50 years

The Chiefs’ dramatic comeback ended Australian punter Mitch Wishnowsky's Super Bowl dream.

Wishnowsky was aiming to become the first Aussie to play in a winning Super Bowl, but it wasn’t to be.

Uncomfortable and under duress for much of the game, Mahomes suddenly recaptured his mojo - and lifted Andy Reid and the Chiefs to a Super Bowl victory - the team's first NFL championship in a half-century.

All it took was falling behind by double digits in the postseason again. Then Mahomes, selected MVP, hit two long passes on touchdown drives.

The vaunted 49ers defense wilted late, particularly on passes of 44 yards to Tyreek Hill and 38 to Sammy Watkins.

The touchdowns came on short throws to Travis Kelce to cut the deficit to three and to Williams for the lead.

The first NFL title in Chiefs coach Reid's two-decade career was clinched by Williams' 38-yard TD run, sending red-clad Chiefs fan into chants of “Andy!'' Andy!”

Reid, 61, won a Super Bowl ring with the 1996 Packers while in charge of tight ends. He's been seeking one as a head coach since being hired by Philadelphia in 1999. The Eagles lost in their only trip to the big game after the 2004 season.

The Chiefs (15-4) trailed 24-0 and 17-7 in their previous playoff games.

Their fans in the crowd of 62,417 at Hard Rock Stadium got little opportunity to chant and do the tomahawk chop as KC fell behind 20-10 with 17 1-2 minutes remaining.

Mahomes even threw his second interception of the night after that. But then came the kind of Mahomes magic that makes him special.
