The committee has scheduled a contempt vote for June 20.

To date, the Justice Department has produced 7,600 pages of documents to the committee.

Darrell Issa, chairman of the House Oversight and Government Reform Committee, says Congress needs to examine records regarding the Justice Department’s conduct following public disclosures in early 2011 that hundreds of guns illicitly purchased at gun shops on the U.S. side of the border wound up in Mexico, many of them at crime scenes.

The Justice Department says many of the documents deal with open criminal investigations and prosecutions — matters relating to sensitive law enforcement activities that cannot be disclosed.

“The Justice Department is out of excuses,” House Speaker John Boehner said Monday. “Congress has given Attorney General Holder more than enough time to fully cooperate with its investigation into Fast and Furious,” the name of the flawed law enforcement operation.

Issa said Congress has an obligation “to investigate unanswered questions about attempts to smear whistleblowers, failures by Justice Department officials to be truthful and candid with the congressional investigation and the reasons for the significant delay in acknowledging reckless conduct in Operation Fast and Furious.”

Sen. Chuck Grassley, whose investigation first turned up problems in Operation Fast and Furious, said the action by the House committee “is straightforward and necessary. Contempt is the only tool Congress has to enforce a subpoena.”
