The Office of Information and Regulatory Affairs (OIRA), a little-known but highly influential arm of the Office of Management and Budget (OMB), wields significant authority over the federal regulatory process. Operating largely outside public view, OIRA does not enact laws or directly command agencies. Instead, it serves as a critical checkpoint: reviewing, delaying, revising, or halting proposed regulations from executive branch agencies before they can take effect.
This centralized review process affects a wide range of rules covering environmental protection, labor standards, public health, consumer safety, and more. Federal agencies may invest years in crafting detailed regulations based on scientific, economic, and legal analysis. Yet OIRA can extend review periods indefinitely, demand substantial changes, or return rules for further work—all without mandatory public hearings, detailed explanations in many cases, or rigid deadlines. The process emphasizes cost-benefit analysis, interagency coordination, and alignment with broader administration priorities.
