Its founder, a longtime Murtha aide whose business dealings with the Congressman have attracted scrutiny, could be on his way out.

The PMA Group, founded by former Murtha staffer Paul Magliocchetti, might soon part ways with Magliocchetti. Patrick Dorton, a PMA Group spokesman, told WJACTV.com, "There are ongoing discussions inside the firm about its future business structure."

Multiple sources told WJACTV.com PMA and Magliocchetti could soon part ways.

Several government watchdog groups have criticized the connection between PMA Group's campaign donations and lucrative earmarks secured by Murtha. According to Citizens for Ethics and Responsibility in Washington, PMA Group and its clients contributed $381,000 to Murtha's campaign and political action committee between 2005 and 2008. During the same period of time, reports show PMA secured at least $95 million in federal earmark money.

Magliocchetti served several years as an aide to Murtha's House Appropriations Subcommittee on Defense during the 1980s. Shortly after ending his work on Capitol Hill, Magliocchetti helped found the PMA Group, which shares his initials.

This news surfaces at a time when Murtha and another major benefactor are under increasing scrutiny. Federal agents raided Windber-based Kuchera Industries, another large recipient of federal defense earmarks, last week. Kuchera, like PMA Group, has donated thousands of dollars to Murtha's congressional campaigns.

A Jan. 24 edition of Politico newspaper reports, "According to two sources, in recent months FBI agents have begun looking into Murtha's earmarks and his relationship with lobbying firms and contractors that get those earmarks."

A spokeswoman for the United States Attorney's office for Western Pennsylvania confirms federal agents raided the Kuchera properties last week. But she would neither confirm nor deny whether Murtha and the PMA Group are also under investigation.

Murtha's office did not respond to requests for comment.
