22 states sue Trump over repeal of Obama-era power plant rules

A coalition of mostly Democratic-led states has filed a lawsuit against the Trump administration, arguing its rules for addressing power plant pollution are so weak they violate federal law.

Attorneys general from 22 states and several major cities including New York City and Los Angeles argue that the Trump administration's rule violates the Clean Air Act by having virtually no impact on carbon emissions.

The Environmental Protection Agency (EPA) had finalized the rule in June to repeal and replace a capstone Obama-era carbon pollution regulation they say exceeded agency authority.
