War on error: Donald Trump accidentally says 7-Eleven instead of 9/11

At a campaign rally on the eve of the New York primary, Donald Trump read aloud an emotional testimonial on what he considers “New York values” and mistakenly said 7-Eleven instead of 9/11.
“I wrote this out, and it’s very close to my heart - because I was down there, and I watched our police and our firemen down on 7-Eleven, down at the World Trade Centre, right after it came down, and I saw the greatest people I’ve ever seen in action,” Trump said at a rally near the Buffalo waterfront on Monday evening, without stopping to correct himself. “I saw the bravest people I’ve ever seen, including the construction workers, including every person down there. That’s what New York values is about.”
He frequently mentions the 2001 terrorist attacks, although he usually cites the proper date.
