PITTSBURGH — The public corruption retrial of state Sen. Jane Orie and her sister, Janine, has been pushed back two weeks because the senator’s attorney expects to be busy defending House Speaker Bill DeWeese in a separate corruption trial.

Allegheny County Judge Jeffrey Manning pushed the Orie retrial back from Feb. 13 to Feb. 27 to give attorney William Costopoulos time to wrap up the trial of DeWeese, a Greene County Democrat, whose trial was to begin Wednesday.

The 50-year-old Republican senator and her 57-year-old sister are charged with using Orie’s state paid staff to do campaign work that benefited the senator and a third sister, state Supreme Court Justice Joan Orie Melvin. The retrial also includes new charges that Jane Orie forged and lied about defense documents, prompting a mistrial in March.
