Top officials at Trump's EPA impeding inquiry into chief of staff, watchdog says

Andrew Wheeler's top agency lawyer argues political staffers have leeway to decide what information to provide to investigation

Top political appointees at Donald Trump's environment agency are hindering an investigation into the agency's chief of staff, who pressured a prominent scientist to alter her congressional testimony to make it more favorable for the agency, according to an ethics watchdog.

In the latest development of the fight, the inspector general of the Environmental Protection Agency (EPA) has forced the agency's head, Andrew Wheeler to explain his position in a letter to Congress. Wheeler's top agency lawyer is arguing that political staffers have leeway to decide what information to provide to the watchdog, while investigators are warning that agency leaders are trying to subvert their legally mandated independence.
