State Attorney General Eric Schneiderman is spearheading an effort to save one of President Barack Obama's plans to curb global warming.
In a letter sent Thursday, Democratic attorneys general in 15 states urged President-elect Donald Trump to preserve Obama's Clean Power Plan. It seeks to reduce greenhouse gas emissions from power plants by about one-third by 2030, but it's being blocked by lawsuits from states and fossil-fuel companies.
The Supreme Court halted the plan in February while the lower court reviews the litigation.
While a ruling is expected soon, earlier this month, a group of mostly Republican officials in 24 states called on Trump to take executive action to nix the plan. They say the EPA lacks authority to implement the rules.
Trump has said he would repeal the plan within his first 100 days in office.
