Everyone has an opinion. The facts are that Congress totally controls agency funding, mission, accountability, and accomplishments. There’s nothing illegal about an agency executing the missions that Congress has directed by law. And when/if there is an overstepping of authority, the courts typically remedy the situation, and/or Congress deals with it. There are plenty of successful court challenges that rescind agency decisions. But the facts are that there are legal requirements established by Congress for any rule making and all are published daily in the federal register. Nothing is developed without the legal processes directed by laws established by Congress. Don’t believe the people who state otherwise; they don’t know what they’re talking about. Agencies operate to execute laws passed by congress.
