PITTSBURGH — State Sen. Jane Orie and one of her sisters today were held for trial on charges they used the lawmaker's taxpayer-funded staff for campaign purposes.

Allegheny County Judge Donna Jo McDaniel ordered Jane and Janine Orie to stand trial for allegedly conspiring to use the senator's staff for campaign work for the lawmaker and a third sister, state Supreme Court Justice Joan Orie Melvin. Janine Orie worked as an aide to the judge.

A series of former Orie staffers testified during a three-day preliminary hearing that they did campaign work at Sen. Orie's direction.

The Ories have denied the allegations.

Melvin has not been charged.

Sen. Orie represents southern Butler County.
