Issa is a pitbull.

WASHINGTON (AP) — The Republican chairman of a House panel looking into the attacks on the U.S. consulate in Benghazi, Libya, wants to take depositions from the leaders of an earlier review board.

California’s Rep. Darrell Issa, head of the Oversight and Government Reform Committee, on Sunday said he would like to interview under oath former Ambassador Thomas Pickering and retired Adm. Mike Mullen, the former chairman of the Joint Chiefs of Staff. Pickering and Mullen led an investigation that examined the September attacks that killed four Americans, including an ambassador.

Democratic Sen. Dianne Feinstein of California says Congress’ review seems aimed at discrediting former Secretary of State Hillary Rodham Clinton and her potential 2016 presidential bid.

The State Department’s IG is already investigating the panel for failing to interview key witnesses.

Via Fox News (May 2, 2013):

The State Department’s Office of Inspector General is investigating the special internal panel that probed the Benghazi terror attack for the State Department, Fox News has confirmed.

The IG’s office is said by well-placed sources to be seeking to determine whether the Accountability Review Board, or ARB — led by former U.N. Ambassador Thomas Pickering and former Chairman of the Joint Chiefs of Staff Adm. Mike Mullen — failed to interview key witnesses who had asked to provide their accounts of the Benghazi attacks to the panel.

The IG’s office notified the department of the “special review” on March 28, according to Doug Welty, the congressional and public affairs officer of the IG’s office.
