House Republicans accused the Obama administration of “generally making a mockery” of the congressional oversight process, as they fight in a federal appeals court for documents related to a flawed gun-tracking initiative known as Operation Fast and Furious.

The House Oversight and Government Reform Committee, in a brief filed Thursday at the U.S. Court of Appeals for the District of Columbia Circuit, argued that a lower court judge did not fully correct the Justice Department’s “executive abuses” as it responded to a congressional subpoena.

“DOJ responded by lying to Congress; engaging in concerted resistance, delay and gamesmanship; refusing to produce a privilege log for more than three years; belatedly raising new purported grounds for withholding documents long after the fact; and generally making a mockery of the process of negotiation and accommodation that is supposed to facilitate the exercise of Congress’s oversight and investigative powers,” the brief stated.

The lower courts allowed the Justice Department to benefit from that response, the committee argued, preventing the House from completing its obstruction of Congress investigation.

“This court should restore balance to the congressional oversight process by correcting the errors of the district court and compelling DOJ to produce in full, at long last, the entirety of the documents sought in the complaint,” the brief stated.
