Senator Dianne Feinstein (D-CA) wants the Attorney General to explain why the public corruption unit of the U.S. Attorneys Office in Los Angeles was shut down.  That's the office investigation Rep. Jerry Lewis (R-CA), who was named one of the most corrupt members of Congress in CREW's report, Beyond DeLay.

According to The Hill, Feinstein is demanding an explanation:

Sen. Dianne Feinstein (D-Calif.) on Wednesday called on Attorney General Michael Mukasey to explain the decision to eliminate the public corruption unit in Los Angeles that has been investigating Rep. Jerry Lewis's (R-Calif.) ties to a lobbying firm.

The U.S. Attorney for the central district of California in Los Angeles reassigned the 17 lawyers in the public corruption unit and disbanded it earlier this month. The decision has stirred ill will and low morale within the office and raised questions about whether pending and future public corruption cases will be rigorously pursued, according to press accounts.

Attorneys in the Los Angeles office have spent years reviewing an FBI investigation into Lewis's connection to a lobbying firm and the earmarks its clients received. Lewis has doled out more than a million dollars in attorney fees related to the probe.
