State Attorney General Kathleen Kane is expected to testify Wednesday at a hearing involving the political corruption probe her office shuttered over alleged concerns of racism, although her office is seeking to limit her testimony.

Prosecutors from the Philadelphia District Attorney's Office, which took up the prosecution of several state legislators after her office declined to bring charges, recently sought to compel Kane's testimony at a pretrial hearing in the case against Rep. Louise E. Bishop, D-Philadelphia. The subpoena required Kane to testify at a hearing set for 11 a.m. Wednesday at the Dauphin County Courthouse.

Frank Fina, the lead prosecutor who conducted the probe, is also set to take the stand Wednesday. Fina, who now works at the Philadelphia District Attorney's Office, is expected to discuss whether race played a role in the investigation that allegedly targeted black legislators. Bishop's attorney, A. Charles Peruto Jr., filed the motion to compel Fina's testimony.
