It would be foolish and naive to doubt that some Muslims in the US were celebrating. I’m sure there were some.
And I know that thousands - probably millions - around the world were celebrating.
Trump’s “thousands” remark referred to NJ.
Trump eliciting hyperbole? Say it ain’t so! LOL!
Many of those calls, said Burkett, came from concerned and angry Americans reporting Muslims celebrating over the destruction of the twin towers and damage to the Pentagon. The calls were logged, reports were made and there were "stacks and stacks" of them, he said.
