Group of 23 states file lawsuit against EPA over power plant restrictions again

President Barack Obama's central plan to fight climate change is under fire from nearly half the states in the nation, which have filed two lawsuits in the last two weeks challenging the EPA's mandates to cut the power industry's carbon emissions by a third by 2030.

Tuesday's suit, filed in the U.S. Court of Appeals in Washington, D.C., follows similar legal action taken last month by a 24-state coalition that seeks to revoke the Obama administration's Clean Power Plan -- an initiative that would drastically slash carbon emissions over the next 15 years.
