WASHINGTON (AP) — Aiming at the heart of President Barack Obama’s strategy for fighting climate change, the Republican-controlled House voted Thursday to block the administration’s plan to limit carbon pollution from new power plants.

The bill targets Obama’s proposal for the Environmental Protection Agency to set the first national limits on heat-trapping carbon pollution from future power plants. It’s part of the GOP’s election-year strategy to fight back against what Republicans call a “war on coal” by the Obama administration.
