State Rep. Daryl Metcalfe is taking conservative outrage over Attorney General Kathleen Kane's decision to recuse herself from the defense of Pennsylvania's marriage statute to a new level.

On Monday, Metcalfe, a Republican from Butler County and one of the state House's most outspoken conservatives, began circulating a memo seeking co-sponsors to a planned resolution calling for Kane's impeachment.

He had hinted at his plans to do this earlier this summer.

Metcalfe stated his motivation is Kane's declaration this summer that she would not defend Pennsylvania's law defining marriage as the union of one man and one woman against a legal challenge.

Kane, a Democrat elected last year, said then that she was ethically bound to turn the case over to the Gov. Tom Corbett’s Office of General Counsel because she personally believed the same law to be unconstitutional.

In his memo, first reported Monday by The Morning Call of Allentown, Metcalfe accused Kane of “creating a constitutional crisis by refusing to perform he assigned role and usurping the role of the courts.”

He argued the attorney general’s decision and her public comments about it violated the state’s Constitution, the Commonwealth Attorney’s Act, as well as a lawyer’s ethical obligations.

“It is our duty,” he continued, “to stop her from engaging in further misbehavior in office.”

Kane’s office could not be reached for comment on this report.

According to the Pennsylvania Constitution, the state House can vote to initiate impeachment proceedings designed to remove elected officials due to “misbehavior in office.”

It is extremely rare, but if a resolution like that being drafted by Metcalfe were to pass, it would result in an impeachment trial in the state Senate. There, a two-thirds vote of all members present would be required to sustain a conviction.
