Once again, the House Judiciary Committee is trying to get the Republican National Committee to turn over a stack of documents for its probe of the firing of U.S. attorneys for political reasons.

The HJC's interest in the documents comes after previous Justice Department emails revealed that Karl Rove and his aides often used the RNC email accounts to communicate about the U.S. attorneys.

The committee subpoenaed the RNC for the documents last year. The RNC refused and the House Judiciary Committee chair, Rep. John Conyers (D-MI), threatened the chairman of the RNC with contempt of Congress.

Today, Conyers takes up the fight again with a fresh letter to the RNC. Conyers reiterates the request and points to last week's court ruling when a federal judge dismissed the White House claims to blanket immunity from Congressional oversight.

Although the case did not address the RNC specifically, Conyers says the ruling gives the RNC no excuse for not complying with the 13-month-old subpoena.
