► At a House Oversight and Government Reform Committee hearing on the attack on the U.S. embassy in Benghazi, state department officials revealed new details and presented their views, which conflicted with earlier official responses. Foreign Service officer Gregory Hicks told the committee that “the U.S. military could have blunted the attack by scrambling intimidating military aircraft from Italy's Aviano Air Base -- an assertion denied by Joint Chiefs Chairman Martin Dempsey when he testified before Congress in February,” according to CNN. “Clinton and her senior aides should have paid more attention to deteriorating security in Libya over the months preceding the attacks, along with requests from the post for additional resources, said Eric Nordstrom, who served as the embassy’s security chief until July,” reports the Washington Post. There were also assertions that the terror connection was clear from the beginning. Popular Mechanics magazine looks at lessons from Benghazi that can be learned separate from the political debate in a piece that discusses the challenges of staging military assets to be ready for emergency responses.
