In introducing the "New York Values" segment of his speech in Buffalo's First Niagara Center on Monday night, Donald Trump inadvertently referred to the Sept. 11, 2001, terrorist attacks as "7-11" -- the name of a national convenience store chain -- instead of "9/11."
"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," Trump said as he began talking about "New York values."
News and video of the Republican presidential candidate's gaffe has already spread as far as CNN, Gawker, Slate and the New York Daily News.
