Federal Agencies and the Future of Presidential Power
Thu Nov 20 2025
In principle, federal agency missions are set when agencies are created, and so remain rooted in the ambitions of the president and the Congress who decided they were necessary. But in reality, political change tends to transform agencies’ missions in both subject and scope. Understanding how this occurs can clarify the nature of presidential power and the character of constitutional evolution.
Guest Tevi Troy joins us to discuss how agency missions have changed during recent presidential administrations, and how Congress can act to restore the constitutional separation of powers.
Tevi Troy is a senior fellow at the Ronald Reagan Institute, a former deputy secretary of Health and Human Services, and former senior White House aide. He is the author of five books on the presidency, including The Power and the Money: The Epic Clashes between Commanders in Chief and Titans of Industry (Regnery History, 2024).
This podcast discusses themes from Tevi’s essay in the Fall 2025 issue of National Affairs, “Who Gives Federal Agencies Their Purpose?”
