Carol Browner, EPA Administrator under Bill Clinton, said, "Under Pruitt, what they're doing is conscientiously tearing the place down." Christine Todd Whitman, EPA Administrator under George W. Bush, said it was "mindless" that under Pruitt, policies enacted under Obama were being reversed regardless of their merits or shortcomings. Gina McCarthy, EPA Administrator under Barack Obama, said that Pruitt's EPA had created a "wealth of uncertainty" in undoing so many regulations because businesses would not know if they should "take rules seriously".
