Tonight on “The Kelly File,” Judge Andrew Napolitano weighed in on FBI Director James Comey’s remarks on “60 Minutes” about U.S. terror fighters.

“Ultimately, an American citizen, unless their passport is revoked, is entitled to come back. So someone who has fought with [ISIS] with an American passport and wants to come back, we will track them very carefully,” Comey said.
