Media outlets in Pennsylvania are reporting that federal agents have raided the offices of a defense contractor with close ties to Rep. John Murtha (D-Pa.).

The Johnstown Tribune-Democrat reported Thursday afternoon that Federal Bureau of Investigation and Internal Revenue Service agents raided the offices of Kuchera Defense Systems and Kuchera Industries in Windber, Pa.

Murtha has provided millions of dollars worth of earmarks for the company, and company employees have provided tens of thousands of dollars for his campaign.

There is no indication what investigators are looking for and no suggestions that the investigation in any way involves Murtha.

Murtha’s office did not immediately respond to a request for comment.
