Donald Trump Brutally Mocked After Calamitous Error In His Super Bowl Tweet

US President Donald Trump has been branded a "stone-cold idiot" after he made a shocking error in his celebratory Super Bowl tweet.

And Trump, 73, took to Twitter to congratulate the Kansas City Chiefs in a now-deleted tweet and praised them for successfully representing the "Great State of Kansas."

The US President tweeted: "Congratulations to the Kansas City Chiefs on a great game and a fantastic comeback, under immense pressure.

"You represented the Great State of Kansas and, in fact, the entire USA, so very well. Our Country is PROUD OF YOU!"

However, the polarising Trump was left red-faced after learning that the Kansas City Chiefs don't come from Kansas.

Instead, the newly-crowned Super Bowl LIV winner's Arrowhead Stadium is based in Kansas City, Missouri.

The US President might have deleted the tweet, but that didn't stop him from being put on blast on social media.

Former Missouri Senator Claire McCaskill came out with a scathing attack on Trump and called him a "stone-cold idiot" on Twitter.

Trump posted an updated -- and corrected -- version of the tweet by replacing the "Great State of Kansas" with the "Great State of Missouri."

The 73-year-old said in his refreshed tweet: "Congratulations to the Kansas City Chiefs on a great game and a fantastic comeback under immense pressure. We are proud of you and the Great State of Missouri. You are true Champions!"
