"Scott Pruitt, the current head of the Environmental Protection Agency, first came to national prominence back when he was Oklahoma's attorney general. In that role, he sued the agency he now runs 14 times, in a series of court cases alleging overreach by the federal government.

Environmentalists in Pruitt's home state say Pruitt was much less aggressive when it came to enforcing Oklahoma's environmental laws and going after polluters. An examination of Pruitt's record on environmental issues in Oklahoma shows that Pruitt's positions were often more in line with business and industry than with environmentalists.

As EPA administrator, Pruitt has aggressively pursued an agenda to roll back Obama-era regulations on vehicle emissions standards, water quality and the climate. Pruitt has also said that he believes the science behind climate change should be up for debate."
