Roll Call: "Visclosky’s Top Aide Resigns"

More corruption issues here:

Chuck Brimmer has resigned as chief of staff to Rep. Peter Visclosky (D-Ind.) after being served with a subpoena as part of the federal grand jury probe of the PMA Group, a now-defunct lobbying firm.

The news came as Visclosky announced Tuesday that he is handing off control of the energy and water spending bill while the federal inquiry proceeds.

Visclosky spokesman Jacob Ritvo confirmed that Brimmer “has retired,” citing “respect for the process” in declining to comment further.

Visclosky on Friday announced that some staffers — and his Congressional and campaign offices — had been subpoenaed in the probe. Brimmer disclosed the development in a letter that was read into the Congressional record on Tuesday. He was the only Visclosky aide to report being served.

Brimmer has worked for Visclosky on and off since at least 2000, according to salary figures posted on LegiStorm, a Web site that tracks Congressional information. While on Visclosky’s payroll, Brimmer mostly split his time between the lawmaker’s personal office and the Appropriations Committee. . . . .
