(CBS News) CBS News has learned that the House Oversight Committee expects to file a civil contempt suit against Attorney General Eric Holder Monday. The lawsuit is to try to force Holder to release documents from the Fast and Furious gunwalking operation. The Republican-led House of Representative voted to hold Holder in contempt on June 28 for failing to turn over thousands of pages of subpoenaed documents. The Justice Department has said it is withholding documents under White House executive privilege.
