The Environmental Protection Agency’s enforcement office has told employees to direct any outside inquiries to a small group of officials rather than answer the questions themselves. According to the Washington Post, an EPA memo cites any contact from reporters, congressional investigators and the EPA’s inspector general. The memo says: “Please do not respond to questions or make any statements.” Critics say the move will further endanger employees who speak out against political interference with their work. A recent survey found more than half of EPA officials have encountered political interference in the past five years.
