Here's the
2001 quote that Trump is citing:
In Jersey City, within hours of two jetliners' plowing into the World Trade Center, 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.
That's not exactly comprehensive proof of Trump's
"thousands and thousands" claim.
Also, I can see why someone would not remember a particular sentence in an article he wrote fourteen years before.
