Federalism is the core principle of the U.S. government. Trump is undermining it.

America is built upon the principle of federalism, a form of government in which power is balanced and responsibilities are shared between the states and the federal government. The Trump administration, however, is increasingly undermining it by using the levers of the federal government to impose its ideology upon the states. “These efforts to try to insinuate federal control in areas where it’s not supposed to be operating is sort of breaking down this really important barrier that we have against a truly authoritarian government,” Vox Senior Correspondent Zack Beauchamp tells Ali Velshi.
