PITTSBURGH — A person familiar with the dealings of an Allegheny County grand jury says an indictment will be returned Wednesday in the investigation into whether campaign work was being done in Sen. Jane Orie's office on state time.

The person could not comment for the record because the grand jury's findings are secret until they are returned. The person would not say who will be charged.

Orie represents a part of southern Butler County.

Allegheny County District Attorney Stephen Zappala confirmed in January that he was investigating claims by the Republican state senator's former intern. The intern says Orie's staff performed campaign work for the senator's sister, state Supreme Court Justice Joan Orie Melvin, on state time.

Orie and her attorney did not immediately return calls Tuesday.
