In the US state of Oregon, 11 Republican Party senators have gone into hiding and state police are trying to track them down.
They fled the capital, Salem, three days ago in an attempt to stop a landmark climate-change bill from passing. Oregon's Democrats, who have a clear senate majority, want to pass legislation capping carbon emissions, and the Republican senators have removed themselves to deny the senate a quorum.
Over the weekend, the state capitol had to shut down altogether amid apparent security threats from militia groups.
