On Capitol Hill Monday, scores of protesters flooded the hallways outside the offices of Republican lawmakers who voted in favor of a massive rewrite of the U.S. tax code. Police arrested at least 11 as they sat in nonviolently and refused to leave, chanting, “Tax the rich, not the poor and sick.” The protests came as the House approved a measure to send their version of the tax cut bill to a conference committee to reconcile differences with a version that passed the Senate on Saturday.
