Biden is not the first president to disregard legislative authority. But these members of the legislative branch are beseeching their leader to ignore them and their constitutional authority. Indeed, the most important power given to Congress under Article I is the “power of the purse.” It was the ultimate control over government. Whatever entanglements or commitments a president may seek, he must ultimately get the Congress to go along.George Mason captured that intent when he declared that “no branch of government should ever be able to combine the power of the sword with the power of the purse.”This purported 14th Amendment loophole would reduce the separation of powers doctrine to junk bond status.
It's shocking to think that Elizabeth Warren used to be a law professor. She's now an acolyte of the Laurence Tribe school of "anything goes."
