Benghazi panel questions Clinton aide amid public spat

Jake Sullivan, a former policy director and deputy chief of staff under Clinton at the State Department, was questioned by the panel in a daylong session of testimony behind closed doors.

Rep. Trey Gowdy, R-S.C., the committee's chairman, said Sullivan was in a "unique position" to talk about how U.S. policy in Libya required the State Department to have a physical presence in the country. Sullivan is currently a top policy aide on Clinton's presidential campaign.
