"EPA air chief Bill Wehrum refused for 10 months to release a recusal letter detailing his past work representing chemical manufacturers, refiners, oil drillers and coal-fired power plants.
But he was concerned about his potential conflicts of interest long before he caved under political pressure and released the letter, newly released emails show.
Two days after joining EPA, Wehrum requested a detailed list of the clients he had represented as an attorney in private practice, according to the emails released to the Sierra Club following Freedom of Information Act litigation.
"Can you send me a list of all clients to whom I billed time for the past 24 months?" Wehrum wrote to a former colleague at the law firm that is now Hunton Andrews Kurth LLP on Nov. 14, 2017."
