A live stream of this confirmation hearing is available via C-SPAN.
Oklahoma Attorney General Scott Pruitt has been among the most controversial picks for Donald Trump's Cabinet. In part, that's because the Environmental Protection Agency nominee has said things like this:
"Scientists continue to disagree about the degree and extent of global warming and its connection to the actions of mankind. That debate should be encouraged — in classrooms, public forums, and the halls of Congress."
As Oklahoma's lead attorney, Pruitt has also been a leader in going after the environmental agency, joining other Republican attorneys general in lawsuits to try to stop, among other things, ozone and methane emissions regulations and Obama's signature climate plan.
Pruitt has also been public in his defense of coal, oil and natural gas — all industries the EPA oversees. In a 2013 interview he said, "I think the attitude with the EPA and certain environmental groups is that fossil fuels are bad — period. And they're doing everything they can to use the rule-making process to attack."
For all this, he may face stiff opposition in Wednesday's confirmation hearing.
