U.S. diplomat recounts lack of response to deadly Benghazi attack

WASHINGTON (Reuters) - A former U.S. diplomat in Libya told lawmakers on Wednesday more could have been done to prevent last year's deadly assault on the U.S. mission in Benghazi in which the U.S. ambassador was killed.

In a congressional hearing marked by emotional testimony and angry charges of political partisanship, Gregory Hicks, deputy chief of mission in Libya at the time of last year's attack, became the first U.S. official on the ground in Libya during the attacks to testify publicly.
