Just the New Jersey part.
Except the WaPo actually printed a story in 2001 after 09-11 confirming his statement about Muslim celebrating in NJ.
I think "fabricate" may be too strong a word. The human mind--and human memory--is a funny thing. Especially remembering things from high-stress situations (like we all experienced on and after 9/11).
It's the reason why, if you interview ten eyewitnesses to a crime, you will get ten different stories. And if you interview the same eyewitnesses ten years later, you'll get another ten different stories. It's not that the witnesses are lying, it's that humans are imperfect, and we remember things imperfectly.
Nope, also not fabricated:
Sept 18, 2001 - Washingtonpost
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.
You may wish to dispute anything but not the New Jersey part. My nephew a fire captain in Passaic was called on 9/11 as were 50-75 others with engines from Passaic, Essex and Bergen Counties to go to Paterson and other towns including Jersey City to quell riots caused by celebrating Arabs (mainly Palestinians) on 9/11. The Paterson riots arose when black citizen patriots went after the celebrants. Unless the State of New Jersey has destroyed the fire alarm records and call reports, they will prove Trump 100% accurate. (Posted on other threads as well.)
