The Justice Department unsealed an indictment on Monday charging five men in connection with the killing of Border Patrol agent Brian Terry.

The 11-count indictment is a major development in the scandal surrounding Operation Fast and Furious, which authorized the sale of nearly 2,000 guns — including two found at Terry’s murder scene — to straw buyers for Mexican drug cartels.

Rep. Darrell Issa (R-Calif.), who has led the Congressional probe into Fast and Furious and spearheaded placing Attorney General Eric Holder in contempt of Congress for allegedly not cooperating with the investigation, called the unsealing of the indictments politically motivated.

Issa said the DOJ’s announcement was the Obama administration’s attempt to place “politics over good policy” because it came so closely on the heels of the House’s vote to place Holder in contempt.

Issa, the chairman of the House Oversight and Government Reform Committee, has been grilling the DOJ for more than 16 months over its involvement in Fast and Furious.
