"The Environmental Protection Agency’s proposal to limit carbon pollution from the electricity sector is the centerpiece of the President’s plan to address climate change, and the foundation for U.S. leadership on an international climate agreement. In an effort to kill the rule, the industry has shrewdly hired Larry Tribe, our Harvard Law School faculty colleague and perhaps the nation’s most famous constitutional law professor, who is arguing on their behalf that the rule is unconstitutional. Like most proposed rules, the Administration’s climate rule is far from perfect, but sweeping assertions of unconstitutionality are baseless. Were Professor Tribe’s name not attached to them, no one would take them seriously."
