Benghazi panel interviews former Clinton chief of staff

A former top aide to Hillary Clinton was brought in by the House committee probing the deadly Benghazi attacks to answer questions Thursday in a closed-door deposition, as her role in the former secretary of state's inner circle comes into focus with the latest release of Clinton emails.

Meeting behind closed doors from roughly 8:30 am until 6 pm, members of the panel were questioning Cheryl Mills, Clinton's former chief of staff. Jake Sullivan, another former top aide who now works on Clinton's presidential campaign, was set to be interviewed on Friday. Both sessions are off limits to the public.

Republican Rep. Trey Gowdy of South Carolina, chairman of the Benghazi committee, said that Mills "is no different from any other witnesses" who also have been interviewed in private.
