Fox News has learned exclusively today that an arrest has been made in connection with the Sept. 11, 2012 attack that killed four Americans in Benghazi, Libya.

"I can confirm that on Sunday, June 15 the U.S. Military -- in cooperation with law enforcement personnel -- captured Ahmed Abu Khatallah, a key figure in the attacks on U.S. facilities in Benghazi, Libya, in September 2012. He is in U.S. custody in a secure location outside of Libya. There were no civilian casualties related to this operation, and all U.S. personnel involved in the operation have safely departed Libya," Pentagon Press Secretary Rear Admiral John Kirby said in a statement.

Judge Andrew Napolitano reacted moments after the news broke, telling Jenna Lee he expects Khatallah to be tried in federal court in Alexandria, Virginia and be granted all the rights of a defendant in accordance with the Constitution.

Napolitano suggested this arrest could be the government's way of finding out who the actual attackers were.

"He may not be the person who killed Chris Stevens or who ignited the flames that consumed the consulate but he may know the people who did," he explained.

The judge said the government can charge Khatallah with a crime that would bring the death penalty if he is convicted, calling that a "tremendous incentive" for him to give up information in return for a lesser charge.

Watch his full analysis above.
