The Hill:

Senate rejects block to EPA climate regs
The Senate rejected a GOP-backed amendment Wednesday that would have permanently blocked the Environmental Protection Agency from regulating greenhouse gas emissions.
The amendment did not reach the 60 votes necessary for passage. The final vote count was 50-50.
Notably, the amendment did not receive enough votes for Republicans to be able to say that the majority of the Senate wants to block EPA climate rules, as they had hoped.
But Republicans quickly noted that a majority of senators, 64 in total, voted for one of four amendments to block or limit EPA climate regulations.The amendment won the support of four Democrats, including Sens. Mary Landrieu (La.), Joe Manchin (W.Va.), Mark Pryor (Ark.) and Ben Nelson (Neb.). One Republican, Sen. Susan Collins (Maine), voted against the amendment.
The Senate also rejected on Wednesday three alternative amendments offered by Democrats that would limit, rather than eliminate, EPA’s authority to issue climate regulations. See more on those amendments here, here and here.
The White House applauded the Senate’s rejection of the amendments.
