Benghazi

Ahmed Abu Khattala faced days of questioning aboard the USS New York from separate teams of American interrogators, part of a two-step process designed to obtain both national security intelligence and evidence usable in a criminal prosecution.

The case, still in its early stages, is focusing attention on an interrogation strategy that the Obama administration has used in just a few recent terrorism investigations and prosecutions.

The Republicans said this is despite the State Department's pledge to produce 5,000 new pages of documents.

A spokesman for Rep. Trey Gowdy of South Carolina said Tuesday that "nothing has changed" since Gowdy balked Saturday at an announcement by Clinton's presidential campaign that she would testify Oct. 22 before the panel. Gowdy chairs the special committee.

These emails were received from a longtime confidant, including both publicly available and unconfirmed material from sources about the cause of the 2012 attack on the U.S. diplomatic outpost in Benghazi that killed four Americans.

About 180 pages of emails to Clinton from Sidney Blumenthal were released Monday by a Republican-led House panel investigating the attack on Sept. 11, 2012.

Rep. Trey Gowdy, R-S.C., who leads the panel, said the emails were new and were not among those earlier released to the committee by the State Department or Clinton herself.
