A federal judge ordered multiple senior Obama Administration officials, State Department officials and former Hillary Clinton aides Thursday to provide answers under oath to questions requested by Judicial Watch after a roughly four year court battle.

Judicial Watch, a leading conservative non-profit watchdog group, announced the schedule of depositions in their case in a press release Thursday. The Judicial Watch questions regard two separate cases regarding the Obama administration’s actions during the Benghazi terrorist attack on the U.S. Consulate and CIA Annex in Libya, and Hillary Clinton’s use of a private server to send classified government emails.

The Court in our case wants real answers on the Clinton email scandal which is why our request for basic discovery was granted, Tom Fitton

“Judicial Watch is doing the heavy lifting on the ongoing Clinton email scandal, even as Congress dropped the ball and DOJ and State continued to obstruct our quest for the truth,” said Judicial Watch President Tom Fitton, in a press release Thursday. “The Court in our case wants real answers on the Clinton email scandal which is why our request for basic discovery was granted.”

District Judge Royce C. Lamberth ordered senior officials — including Susan Rice, Ben Rhodes, Jacob Sullivan, and FBI official E.W. Priestap – to respond under oath and submit the answers in writing to the questions provided by Judicial Watch. The decision from Lamberth was made this past January.

Lamberth ordered the discovery from the watchdog’s July 2014 FOIA lawsuit, which was filed after the State Department failed to respond to an earlier request made May 13, 2014.

Judicial Watch requests:

Copies of any updates and/or talking points given to Ambassador Rice by the White House or any federal agency concerning, regarding, or related to the September 11, 2012 attack on the U.S. consulate in Benghazi, Libya.

Any and all records or communications concerning, regarding, or relating to talking points or updates on the Benghazi attack given to Ambassador Rice by the White House or any federal agency.

Judicial Watch’s discovery will seek answers to:

Whether Clinton intentionally attempted to evade the Freedom of Information Act (FOIA) by using a non-government email system;

whether the State Department’s efforts to settle this case beginning in late 2014 amounted to bad faith; and

whether the State Department adequately searched for records responsive to Judicial Watch’s FOIA request.

The confirmed discovery schedule now includes:

March 12: State Department’s responses to interrogatories and document requests were due.

March 14: Deposition of Justin Cooper, a former aide to Bill Clinton who reportedly had no security clearance and is believed to have played a key role in setting up Hillary Clinton’s non-government email system.

April 5: Deposition of John Hackett, a State Department records official “immediately responsible for responding to requests for records under the Freedom of Information Act.”

April 16: Deposition of Jacob “Jake” Sullivan, Hillary Clinton’s former senior advisor and deputy chief of staff.

April 23: Deposition of Sheryl Walter, former State Department Director of the Office of Information Programs and Services/Global Information Services.

April 26: Deposition of Gene Smilansky, a State Department lawyer.

April 30. Deposition of Monica Tillery, a State Department official.

May 7: Deposition of Jonathon Wasser, who was a management analyst on the Executive Secretariat staff. Wasser worked for Deputy Director Clarence Finney and was the State Department employee who actually conducted the searches for records in response to FOIA requests to the Office of the Secretary.

May 14: Deposition of Clarence Finney, the deputy director of the Executive Secretariat staff who was the principal advisor and records management expert in the Office of the Secretary responsible for control of all correspondence and records for Hillary Clinton and other State Department officials.

June 11: 30(b)(6) Deposition, which will be designated by the State Department.

June 13: Deposition of Heather Samuelson, the former State Department senior advisor who helped facilitate the State Department’s receipt and release of Hillary Clinton’s emails.

To Be Determined

As yet to be determined is the deposition date for Assistant Secretary for Diplomatic Security Eric Boswell, who wrote a March 2, 2009, internal memorandum titled “Use of Blackberries on Mahogany Row,” in which he strongly advised that the devices not be allowed.
