During a speech in Buffalo, a slip of the tongue meant he referred to the September 11 atrocity as “7-Eleven”, which is in fact the name of a popular chain of convenience stores.Failing to correct himself after the gaffe, the Republican front runner said: “It’s very close to my heart because I was down there, and I watched our police and our firemen down at 7/11, down at the World Trade Center right after it came down, and I saw the greatest people I’ve ever seen in action.”
The mistake could prove embarrassing for Mr Trump as he has repeatedly mentioned the terror attacks while campaigning across New York, his home state.
Earlier this month, he also paid his first visit to the National September 11 Memorial & Museum.
An estimated 11,000 people were attending the rally at a hockey arena – and earlier in his speech, about a dozen protesters interrupted him by locking arms and sitting down on the stadium’s floor.
