Call your senators. Both of them. Tell them the Forest Service reorganization is proceeding without the congressional approval required by Section 716 of the Agriculture Appropriations Act and Section 421 of the Interior Appropriations Act. Use those numbers. Say them out loud. Staffers write down what they don’t recognize, and these are the provisions their bosses voted for.
If your senator is a Republican, the question is simple: you voted for a law that requires USDA to get committee approval before reorganizing or relocating any office. USDA didn’t get that approval. Their own lawyers declared your law unconstitutional. What are you going to do about it?
If your senator is a Democrat, the question is just as simple: the legal basis for stopping this already exists. Where are the subpoenas? Where are the hearings? Why is USDA’s general counsel allowed to declare a duly enacted law unconstitutional by internal memo and face no consequences?
Make them answer. Make their staff write it down. Call back next week and ask what happened.
