As allegations mount of EPA Administrator Scott Pruitt violating ethics policies and misusing taxpayer money, President Trump has repeatedly defended him. "Scott is doing a great job!" he said in one tweet.
Pruitt is one of the administration's most high profile members, and is often lauded as one of its most effective.
"Administrator Pruitt has fearlessly executed President Trump's regulatory reform agenda, there's no doubt about that," says Thomas Pyle, president of the American Energy Alliance.
