Barack Obama claims to be a “professor of constitutional law,” but a genuine constitutional scholar, George Washington University’s Jonathan Turley, a self-acknowledged liberal Obama supporter, has offered severe criticism of Obama’s “über presidency,” his abuse of executive orders and regulations to bypass Congress.

When asked by Fox News host Megyn Kelly how he would respond “to those who say many presidents have issued executive orders on immigration,” Turley responded, “This would be unprecedented, and I think it would be an unprecedented threat to the balance of powers.”

In July, Turley gave congressional testimony concerning Obama’s abuse of executive orders: “When the president went to Congress and said he would go it alone, it obviously raises a concern. There’s no license for going it alone in our system, and what he’s done is very problematic. He’s told agencies not to enforce some laws [and] has effectively rewritten laws through active interpretation that I find very problematic.”

He continued: “Our system is changing in a dangerous and destabilizing way. What’s emerging is an imperial presidency, an über presidency. … The president’s pledge to effectively govern alone is alarming but what is most alarming is his ability to fulfill that pledge. When a president can govern alone, he can become a government unto himself, which is precisely the danger that the Framers sought to avoid in the establishment of our tripartite system of government. … Obama has repeatedly violated this [separation of powers] doctrine in the circumvention of Congress in areas ranging from health care to immigration law to environmental law. … What we are witnessing today is one of the greatest challenges to our constitutional system in the history of this country. We are in the midst of a constitutional crisis with sweeping implications for our system of government. There could be no greater danger for individual liberty. I think the framers would be horrified. … We are now at the constitutional tipping point for our system. … No one in our system can ‘go it alone’ – not Congress, not the courts, and not the president.”

Turley reiterated this week: “[Obama has] become a government of one. … It’s becoming a particularly dangerous moment if the president is going to go forward, particularly after this election, to defy the will of Congress yet again. … What the president is suggesting is tearing at the very fabric of the Constitution. We have a separation of powers … to protect Liberty, to keep any branch from assuming so much authority that they become a threat to Liberty. … The Democrats are creating something very, very dangerous. They’re creating a president who can go it alone – the very danger that are framers sought to avoid in our Constitution. … I hope he does not get away with it.”
