Ex-Navy SEAL who killed bin Laden on marines killed in Kabul airport explosions: It's a 'sad day'

At least 12 Marines killed following suicide bombing in Kabul

Ex-Navy SEAL who killed bin Laden Robert O'Neill discussed terrorism in the Middle East and described the Marines being killed in Kabul as ‘a sad day’ during an appearance on "Cavuto: Coast to Coast," Thursday.

ROBERT O’NEILL: I learned a long time ago, long before the bin Laden raid - when we were in combat with these same groups of people - one of my jobs I had after we assaulted the target was called a battlefield interrogator, where we caught these weaklings who they really are and interrogated them.
