When I took the oath of office as a member of the United States Senate, I swore to “support and defend the Constitution of the United States against all enemies, foreign and domestic.” It is unquestionably my highest duty and responsibility. Unfortunately, Congress has too often exceeded the limited powers granted to it in Article I of the Constitution. Our Presidents have sometimes overreached their power as well. I will work to restore limited government whereby the Legislative, Executive, and Judiciary Branches operate within their constitutional boundaries. This effort starts by limiting the growth of government spending and providing oversight to agencies that expand beyond their congressionally prescribed missions.
