HARRISBURG — All 12 defendants in a Pennsylvania legislative corruption investigation are waiving their arraignments.

That's according to one of the deputy prosecutors for state Attorney General Tom Corbett.

Deputy Attorney General James Reeder said Wednesday all those charged decided not to show up at the Dauphin County Courthouse to hear the charges against them. He said he expects President Judge Richard Lewis to set a trial date soon.

All defendants are connected to the House Democratic caucus and include one sitting state lawmaker. They are accused of overseeing or taking part in a vast operation to divert state dollars and employees for electioneering.

One defendant, the former chief of staff to House Majority Leader Bill DeWeese, said he plans to plead guilty.
