Senate Democrats slammed the Trump administration’s proposed replacement for the Clean Power Plan on Friday, saying it would harm public health while exacerbating the effects of global warming.

A group of Democrats led by Sen. Tom Carper, D-Del., the top Democrat on the Senate Environment and Public Works Committee, sent a letter to Environmental Protection Agency Administrator Scott Pruitt opposing both the EPA’s proposed repeal of the President Barack Obama-era climate plan and its ideas for replacing it. The letter was sent ahead of the midnight deadline to submit comments on the EPA’s repeal of the climate plan.
