Contractor with ties to U.S. Rep. suspended

? A Pennsylvania defense contractor who got millions of dollars in congressional earmarks from Rep. John Murtha has been blocked from doing business with the Navy amid allegations of fraud.

Details of the suspension surfaced Friday as another Democrat who serves on the Murtha-chaired House Appropriations Subcommittee on Defense, Rep. Pete Visclosky of Indiana, was subpoenaed in a Justice Department criminal investigation involving a Washington-area lobbying firm with strong links to both Murtha and Visclosky.

A federal grand jury subpoenaed records relating to a firm known as PMA Group from Visclosky’s congressional office, his campaign committees and from some of Visclosky’s employees. In recent months, FBI agents raided PMA and the suspended Pennsylvania firm, Kuchera Defense Systems Inc.
