According to an Associated Press article describing a new addendum released by the 9/11 Commission, two of the 9/11 hijackers “lied on their applications ‘in detectable ways’ but were not questioned about those lies. And all 19 of the hijackers’ applications had data fields left blank, or were incomplete in some other way.”

Columnist Joel Mowbray first raised concerns about the 9/11 hijackers’ visa applications nearly two years ago in a cover story for National Review. His conclusion: If our immigration laws had been enforced, at least 15 of the 19 hijackers would have been denied visas.
