Watch | Donald Trump’s slip of tongue.

Republican Presidential candidate Donald Trump said 7-11 instead of 9-11 while talking about the September 11th, 2001 terrorist attacks. Trump was talking about the police and firefighters who had responded (April 19). Donald Trump misspoke while on the campaign trail in Buffalo, New York on Monday. He called the attacks of September 11th, 2001 “7-11” instead of 9-11. 7-11 is the name of a chain of convenience stores in the U.S. “I think what I want to do is, I want to talk just for a second, 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 7-11 down at the World Trade Center, right after it came down and I saw the greatest people I've ever seen in action. I saw the bravest people I've ever seen including the construction workers, including every person down there. That's what New York value's about” , said Trump.
