“Thousands of people did not cheer in Jersey City on 9/11. It just didn’t happen. I was there that day. Nothing like that was ever shown on the news. There’s no video of that. It didn’t happen,” Christie told THE WEEKLY STANDARD Tuesday. “As I understand it, he says he saw it on the news. It didn’t happen!”

Christie had previously said Sunday he did not recall the incident Trump has recently described. At a rally last week, Trump said “thousands and thousands of people were cheering” in Jersey City as the World Trade Center buildings across the Hudson River in lower Manhattan. There were no reports of such a large celebration, although the Washington Post did report on September 18, 2001, that law enforcement authorities detained and questioned a number of people who were allegedly seen celebrating the attacks and holding tailgate-style parties on rooftops while they watched the devastation on the other side of the river.” There have also been reports that in Paterson, about 20 miles northwest of Jersey City, a small group of teenagers of Arab descent celebrated in the streets.

But Christie says any celebrations in his state weren’t documented on video and were much smaller—”a small number of people, allegedly”—than Trump has claimed. “As I said Sunday, that was a very emotional, difficult day for me, so I can’t say I have perfect recollection of the day, except for the things that I was really concerned about that day, which was the safety of my wife and my brother,” he said. “But if that had happened, thousands of people in New Jersey cheering, and I’d been named U.S. attorney the day before, I think I would have remembered.”
