The vote that caused Prime Minister David Cameron to resign Friday and prompted financial markets to plunge around the world had its roots at O'Hare airport according to the "Financial Times."
In May 2012, Cameron and entourage were in Chicago for NATO meetings and it was on the way out of town that he was apparently waiting for an American Airlines flight to London when he and two of his top advisors discussed the Brexit idea over pizza in terminal three.
He dined with his foreign secretary, William Hague, and Chief of Staff Ed Llewellyn, according to the Times and now other British Media.
On Friday, Chicago Aviation Department officials responded that Cameron wouldn't have been in O'Hare's public terminals because he flew private and there were extensive NATO security protocols in place.
But on that day in 2012, a British reporter tweeted, "Definite signs of UK austerity: David Cameron is eating at a fast-food joint at O'Hare Airport waiting for a commercial flight home.
A Norwegian reporter tweeted the same day, "Refreshing to spot Cameron eating with regular crowd at O'Hare after two days with tight security at NATO Summit."
Uno Pizzeria executives have not responded to the I-Team's questions neither have executives from the Wolfgang Puck restaurant that also serves pizza there.
Chicago Aviation Department officials reiterated they have no knowledge of such a meeting at O'Hare and referred the I-Team to the prime minister.
A spokesperson for Cameron told the I-Team the press office doesn't know the inner workings of where Brexit was born. In any event, it's likely those early discussions wouldn't have been about an exit from the European Union but rather a broad framework of how the U.K. could get the best deal related to the European Union.
