Ten months into his sentence, ex-Rep. Duke Cunningham (R-CA) is getting some new digs:

Imprisoned former Congressman Randy "Duke" Cunningham will soon have a new address ---- a work camp just outside Tucson, Ariz.

The camp is 410 miles from San Diego, a six-hour drive that will allow the former Republican lawmaker's friends and family members to more easily visit him as he serves an eight-year sentence for taking more than $2.4 million in bribes.

Meanwhile, the investigation presses on, as prosecutors continue to examine whether the defense contractors who bribed Cunningham had similar success with others:

Federal prosecutors in San Diego have subpoenaed documents from three House committees as part of an investigation into special-interest earmarks in spending bills.

The demand ratchets up an investigation by the U.S. attorney's office in San Diego into contracts awarded by the Defense Department and other agencies. The probe stems from the bribery case against Rep. Randy "Duke" Cunningham (R-Rancho Santa Fe), who pleaded guilty and resigned in 2005.

The scope of the investigation is unclear, although the request for documents is considered unusually broad....

The subpoenas went to the armed services, appropriations and intelligence committees, whose Republican chairmen reported the subpoenas to outgoing House Speaker J. Dennis Hastert (R-Ill.) in letters dated two weeks ago....

The subpoenas are an escalation of a nine-month tug-of-war between the Justice Department and House Republicans. Prosecutors had asked the committees to turn over the information voluntarily.
