In a confirmation hearing held by the Senate Judiciary Committee, Sen. Jeff Sessions (R-AL), President-elect Donald Trump’s nominee for Attorney General, said in response to climate change questions posed by Sen. Sheldon Whitehouse (D-RI) that he doesn’t “deny that we have global warming.”

“In fact, the theory always struck me as plausible,” he said. “And it is the question of how much is happening and what the reaction would be to it.” He further said he would make decisions at the Department of Justice based on whether “the facts justify a position.”

In 2015, Sessions called carbon dioxide “plant food” that “doesn’t harm anybody except that it might include temperature increases” and voted against two climate change resolutions.
