HARRISBURG — The top-ranking Republican in the state Senate said Monday the chamber will vote this week on whether to remove from office Attorney General Kathleen Kane, a first-term Democrat who has spent the past two years working to expose an explicit and objectionable government e-mail ring and the past six months fighting her own criminal charges related to a grand jury leak.

Senate President Pro Tempore Joe Scarnati of Jefferson announced the plans for a Wednesday vote under an obscure provision of the state Constitution that, unlike the impeachment procedure, does not have any role for the House. At least 33 yes votes will be required in the 50-seat Senate, which currently has one vacancy.

Kane has repeatedly said the single-chamber procedure in the Senate is illegal, but her spokesman declined to speculate about what action she might take if the supermajority of senators votes to remove her.

“The attorney general believes the Senate’s action is unwarranted and unconstitutional, that our system of justice is founded on a presumption of innocence and she is not being offered that presumption,” her spokesman Chuck Ardo said.

The plans for a vote followed a ruling Friday by the state Supreme Court that denied Kane’s request to have her law license reinstated.

The high court voted 5-0 in September to place her license on temporary, indefinite suspension.
