House Oversight and Government Reform Chairman Darrell Issa plans to sue Attorney General Eric Holder on Monday for refusing to provide documents related to the “Fast and Furious” gun-smuggling operation.

“The committee expects to file the civil contempt suit against the attorney general Monday,” a Republican source said. The suit will be filed in the federal district court for the District of Columbia.

The action is the latest escalation in the dispute between House Republicans and the Justice Department over the documents, which relate to a botched gun-smuggling operation.

On June 28, the House voted to hold Holder in contempt of Congress and authorized the Oversight panel to bring suit to enforce its rights.

In Fast and Furious, agents for the Bureau of Alcohol, Tobacco, Firearms and Explosives allowed assault guns to “walk,” which meant ending surveillance on weapons suspected to be en route to Mexican drug cartels.
