Regarding Obama's unilateral exercise of power to amend legislation, such as altering the O'Care legislation to fit his political agenda, George Washington University Law Prof. Jonathan Turley, an Obama supporter, notes that his actions are a great threat to Rule of Law: "The problem with what the president is doing is that he's not simply posing a danger to the constitutional system. He's becoming the very danger the Constitution was designed to avoid. That is the concentration of power in every single branch."
