Pruitt has argued against environmental regulations and played a role in the 28-state lawsuit against President Obama following his new effort to cut carbon emissions.
Pruitt has called the EPA a "byzantine regulatory regime." He's also called any antagonism toward climate change nonbelievers "un-American."
Addressing climate change is one of the EPA's top priorities. But conservatives like Pruitt have accused the agency of federal overreach.

Trump's pick has been denounced by progressives as a step backward in the fight against climate change.
