In February, speaking before a joint session of Congress, President Trump declared that: “according to data provided by the Department of Justice, the vast majority of individuals convicted of terrorism and terrorism-related offenses since 9/11 came here from outside of our country.” There's a lot of reason to believe this statement is a compound lie—both to believe that the vast majority of individuals convicted of terrorism-related crimes did not come here from elsewhere and to believe that the career men and women of the Department of Justice did not provide any data suggesting otherwise.
