WILLIAMSPORT — Former U.S. Attorney Tom Marino is running for Congress.

Marino announced that he's seeking the Republican nomination to challenge Democratic Rep. Chris Carney in the 10th Congressional District in northeastern Pennsylvania.

The 57-year-old Williamsport native, a former district attorney in Lycoming County, served as the top federal prosecutor for central and northeastern Pennsylvania between 2002 and 2007.

He then worked as in-house counsel for Louis DeNaples, a business magnate and casino owner who has been investigated for possible ties to organized crime. Marino resigned that job last month to run for Congress.

Several Republicans are expected to enter the race to challenge Carney.
