HARRISBURG — Democrats on a state House committee this morning walked out of a hearing on a resolution calling for the impeachment of Pennsylvania Attorney General Kathleen Kane, a fellow Democrat.

State Rep. Daryl Metcalfe, R-12th, of Cranberry Township, is chairman of the committee and organized the hearing.

The Democrats called the hearing an unfair end-run of the parliamentary process. One of them, Philadelphia Rep. Michael O’Brien, called it a “kangaroo court.”

The non-voting hearing of the State Government Committee is devoted to testimony by conservative allies of Metcalfe, the sponsor of the impeachment resolution.

Metcalfe contends, among other things, that Kane broke the law when she refused last year to defend Pennsylvania’s law banning same-sex marriage against a lawsuit. She says the law’s unconstitutional.

Metcalfe called in security officers to eject O’Brien after he interrupted Metcalfe to make a motion. That prompted the Democrats’ protest walkout.
