(WASHINGTON) — As President Barack Obama worked to hammer out a global climate agreement in Paris, Republicans in Congress moved to block his plan to force steep cuts in greenhouse gas emissions from U.S. power plants. The House passed two resolutions Tuesday disapproving Obama’s power-plant rules and rendering them inoperative. A measure blocking an Environmental Protection Agency rule for existing power plants was approved 242-180, while a measure blocking a rule on future power plants was approved 235-188. The votes come after the Senate approved identical motions last month under a little-used law that allows Congress to block executive actions it considers onerous.
