The night before the vital New York primary, at a large campaign rally in Buffalo, Donald Trump got the date of the September 11 attacks wrong.

“I was down there, and I watched our police and our fireman, down there on 7/11, down at the World Trade Center right after it came down,” Trump said, without missing a beat or pausing to correct himself. “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 values are about,” he added, quoting a consistent attack line from rival Ted Cruz.
