During the second wave of attacks on Benghazi, David Ubben was on the rooftops with the Navy SEALS. Eventually, several rounds of mortar attacks found their mark, killing Tyrone Woods and Glen Doherty while shredding David Ubben’s right leg. Ubben was stuck on the rooftop for 20 hours before help arrived.The House Oversight Committee is planning to hold a series of hearings about the 9/11 Benghazi terrorist attack in the Fall. During the last Oversight hearing about the attack, the Obama administration's entire narrative about what happened that night was blown out of the water by State Department Whistleblower Gregory Hicks. Hicks was in Tripoli the night of the attack and was the last person to speak with U.S. Ambassador Chris Stevens before he was killed.
