Eric Nordstom, the regional security officer posted in Libya when the U.S. Embassy was reopened after the country’s 2011 civil war, choked up while delivering his opening statement before a House Oversight Committee hearing on the Benghazi attacks.

"It matters to me personally and it matters to my colleagues at the Department of State," he said of the investigation into the deadly Sept. 11, 2012 assault. Pausing repeatedly to collect himself, he continued, "It matters to the American public for whom we serve and most importantly, it matters to the friends and family of Ambassador Stevens, Sean Smith, Glen Doherty, Tyrone Woods, who were murdered on Sept. 11."

Nordstrom said it was "inexcusable" that the department’s investigation did not review the role of senior leaders in letting the Benghazi compound be occupied despite unmet security standards.

This is not the first time Nordstrom has testified before Congress on Benghazi. Last fall, he made headlines when he said Washington ignored calls for increased security resources for U.S. installations in Libya. His opening remarks from that hearing are here.
