The Supreme Court this week severely undermined the principle that no one is above the law – a bedrock of our nation’s system of government – with its historic ruling declaring that presidents have absolute immunity for their official acts. In her fierce dissent, Justice Sotomayor accused the conservative majority of making the president a “king above the law.” Eminent legal scholar and one of the most cited by SCOTUS, Yale’s Akhil Reed Amar, joins Ali Velshi to discuss the far-reaching implications of this seismic decision. Not mincing words, he calls it “one of the worst decisions in all of constitutional history.” It’s “not just in violation of the Constitution,” says Amar, “but also incoherent.”
