The House Select Committee on Benghazi announced that both Democrats and Republicans want to schedule the appearance of Hillary Clinton “as soon as possible.”

But first, says Chairman Trey Gowdy, R-S.C., the State Department must provide documents originally subpoenaed in 2013 so the materials can be reviewed in order to “constructively ask questions of Secretary Clinton.”

Among the materials sought: documents related to the State Department’s Accountability Review Board investigation and other relevant emails and documents in the possession of the State Department.

For the first time, the committee has also disclosed a partial list of executive branch, military, intelligence and State Department witnesses it intends to interview beginning as early as April 1. It includes Clinton’s top aides Cheryl Mills and Jake Sullivan.

Former Deputy Assistant Secretary Raymond Maxwell told The Daily Signal that Mills and Sullivan together stopped by a Benghazi document-sorting session that he witnessed in the basement of the State Department. Mills, Sullivan and Clinton declined comment. Neither the State Department nor the Justice Department has publicly announced an effort to investigate the claim.

The Benghazi committee also announced that next week it will begin interviewing three dozen firsthand witnesses, including “brave Americans who survived the attacks … and others who can provide indispensable firsthand accounts of what happened before, during and after the attacks.” The committee has not publicly provided the names of these witnesses, who will be interviewed between Feb. 10 and April 1.

As early as April 1, the committee intends to begin interviewing the following (listed in alphabetical order).

1) William Burns: former State Department deputy secretary and Hillary Clinton’s No. 2 at the State Department. He retired from the State Department on Nov. 3, 2014. On Feb. 4, he became president of the Carnegie Endowment for International Peace.

6) Patrick Kennedy: undersecretary of state for management. Sources say that it was Kennedy’s decision to hold back the U.S.-based Foreign Emergency Support Team (FEST) during the Benghazi attacks. Obama officials later argued they couldn’t have gotten there in time to help and aren’t qualified for such a job anyway.

7) Charlene Lamb: deputy assistant secretary for international programs. Lamb was widely faulted as being in charge of the office that denied repeated security requests by U.S. personnel on the ground in Libya, including U.S. Ambassador Chris Stevens, who was killed in the terrorist attacks.

16) Ben Rhodes: Obama deputy national security adviser. Belatedly produced documents show that Rhodes sought to steer blame for the terrorist attacks away from the administration and toward a spontaneous protest narrative.

17) Susan Rice: former U.S. ambassador to the United Nations who forwarded the incorrect narrative of the attacks as spontaneously inspired rather than acts of terrorism. In July 2013, she was promoted to Obama’s national security adviser.
