Republican presidential frontrunner Donald Trump made a September 11th gaffe at a rally in Buffalo Monday. Trump referred to the terrorist attack as “7-11” as opposed to 9/11.

“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,” Trump said at the rally. “And I saw the greatest people I’ve ever seen in action.”

Trump has perpetually railed against his nearest rival in the primary, Texas Sen. [crscore]Ted Cruz[/crscore], for attacking him during a debate before the Iowa caucuses over having “New York values.” Trump accused Cruz for being insensitive toward New Yorkers who went through the 9/11 attacks 15 years ago.

Cruz responded to these accusations by explaining he was referring to the liberal policies from Democratic politicians New Yorkers are governed under.

“They’re the values of liberal Democratic politicians like Andrew Cuomo, like Anthony Weiner and Eliot Spitzer, like Charlie Rangel,” Cruz said.
