PITTSBURGH — Republican state Sen. Jane Orie is scheduled to appear in court next week to answer 16 new charges including perjury and forgery stemming from her testimony and allegedly forged defense documents introduced during her trial earlier this year on charges she used her state-funded staff to do political work.

Orie didn’t comment as she turned herself in Monday night to be arraigned on the new charges filed by Allegheny County District Attorney Stephen Zappala Jr.

Her brother, Jack Orie, who also is an attorney, says the senator is “shocked” by the new charges which suggest Orie herself scanned a document that a judge later determined to be a forgery, prompting him to declare a mistrial of her corruption trial in March.

A preliminary hearing on the new charges has been set for Sept. 7.

A criminal complaint, filed in Pittsburgh City Court, charges Orie with perjury, forgery, and tampering and fabricating physical evidence related to defense documents.
