“Why wouldn’t the Majority Leader bring a bill to the Senate floor to approve President Obama’s climate agenda?” Sessions asked on the Senate floor Monday. “[Because] the American people do not support this and neither does most of Congress.”

Republicans have attacked Obama’s effort to regulate carbon emissions through Environmental Protection Agency (EPA) regulations. They have accused him of waging a “war on coal.”

Sessions said these regulations have burdened the economy and said Democrats don’t want to vote to approve Obama’s policies because some who are up for vulnerable reelections in 2014 wouldn’t support it.

Sessions also said Obama’s claims that global warming is occurring isn’t true.

“Exaggeration isn’t even a fair word to describe it,” Sessions said. “It has become deliberate misinformation. … The climate is not warming faster that experts predicted as the president claimed.”

Most scientists believe global climate change has become more radical as a result of pollution from humans.
