"In a unanimous decision, the Democratic caucus in the Senate wrote a letter on Monday in opposition to the Trump administration’s proposal to axe a 2009 endangerment finding, an Environmental Protection Agency (EPA) determination that concluded that the accumulation of six greenhouse gases posed a serious threat to public health.

The proposal would also repeal regulations for motor vehicles and engines. The determination helped set up the legal basis for U.S. climate policy, according to a press release.

The effort, led by Sen. Sheldon Whitehouse (D-R.I.), ranking member of the Environment and Public Works Committee, and Senate Democratic Leader Chuck Schumer (N.Y.), comes after the Trump administration said it’d axe the finding in July."
