(Salem, OR) -- Republican Representatives shut down the Oregon House when they walked out on Monday. They want an investigation into allegations that Democratic Representative Jason Kropf made a hostile work environment for Representative Thuy Tran. Last week, Tran voted no in committee on a gun bill sponsored by Kropf. They both went outside of the room and when Tran returned, she voted yes. A lobbyist filed a complaint and Republicans say it wasn't adequately investigated. They want the Legislative Equity Office to investigate.
