A federal grand jury has subpoenaed records from Rep. Peter J. Visclosky ’s congressional and campaign offices, along with several employees, in an ongoing probe of now-defunct lobbying firm that specialized in defense-related earmarks, Visclosky, D-Ind., said Friday.

The firm, the PMA Group, once a powerful lobbying shop, sought earmarks from Visclosky and contributed to his campaign, though Visclosky has said he would return at least some contributions related to the firm.

“It is my intention to fully cooperate with the investigation consistent with my constitutional obligations to Congress and my duties and responsibilities to my constituents,” Visclosky said in a statement.

Visclosky, who sits on the Defense Appropriations Subcommittee and leads the Energy-Water Appropriations Subcommittee, which allocates money for the Pentagon’s nuclear programs, earmarked $23.8 million for PMA clients in the fiscal 2008 defense spending bill.

The 13-term lawmaker also is the leading recipient of campaign contributions from PMA’s political action committee and its employees, according to a review by CQ MoneyLine. Visclosky received $219,000 in checks to his political committees since 2001 from those sources.

PMA founder Paul Maglioccetti and each of his nine family members has given to Visclosky at one time or another.

It is not clear whether Visclosky is a target of the probe, and he maintains that he has done nothing wrong.

“I will continue to work hard to represent the people of Indiana’s 1st Congressional District as I have done since being elected to Congress,” Visclosky said. “I am confident that at the end of this process, no one will conclude that I have done anything wrong or harmed my constituents in any way.”

At least two other Democratic lawmakers — Defense Appropriations Subcommittee Chairman John P. Murtha of Pennsylvania, and James P. Moran of Virginia, a member of Murtha’s panel — also face scrutiny stemming from lucrative earmarks they secured for defense contractors represented by PMA. Murtha and Moran also received political donations from Maglioccetti and his family members.

Last month, a group of watchdog groups - Democracy 21, Common Cause, Public Citizen and U.S. PIRG — called for a House ethics probe into Visclosky, Murtha and Moran’s ties to PMA, which disintegrated following a November FBI raid on the firm’s offices.

Murtha spokesman Matthew Mazonkey and Moran spokesman Austin Durrer both said their respective offices had not received any subpoenas for PMA-related documents.
