Senate Minority Leader Jay Costa took to the Senate floor Wednesday to defend Kane and called Rep. Daryl Metcalfe a "bully" who is trying to intimidate Kane.
Costa also urged fellow senators to take steps to condemn Metcalfe's actions.
Metcalfe circulated a memo to other House members this week that sought co-sponsors for articles of impeachment that he plans to introduce. He says Kane, a Democrat, has violated her constitutional, statutory and ethical duties.
At issue are Kane's opinion that the state's same-sex marriage prohibition is not constitutional and her decision to delegate defense of that law in court to Gov. Tom Corbett.
