Trump claimed, "I watched in Jersey City, N.J., where thousands and thousands of people were cheering," but, in fact, he was in his apartment on Fifth Avenue, not in New Jersey. No one has been able to find tv coverage of the imaginary event he described.

Where did you see "enough of them celebrating on American streets"? Were you there?
