Since the Sept. 11, 2001, terrorist attacks in which Al Qaeda terrorists hijacked four flights—crashing one into each of New York City’s Twin Towers, another into the Pentagon, and the fourth into a field in Pennsylvania—a whopping 580 people have been convicted of terrorism in the United States. An even more astonishing 380 of them were foreign-born, according to a release by the office of Sen. Jeff Sessions (R-AL) and a new report from Fox News.
