Congressional aides of both parties described Jackson as one of the most soft-spoken managers on Capitol Hill. Amanda Gunasekara, who will advise the EPA administrator on air and climate issues, had been working for Inhofe less than a month when he asked her to hand him a snowball on the Senate floor two years ago to prove that global warming had not snuffed out winter altogether. Andrew Wheeler, a front-runner to serve as Pruitt's No. 2, served the senator for 14 years before going on to lobby for the coal giant Murray Energy, Xcel Energy and the Nuclear Energy Institute. A few former Inhofe aides — Wheeler, as well as George Sugiyama and Michael Catanzaro, who is now in the White House — have worked at the EPA before.
