"It does seem like it’s major authority."He also noted that tariffs are taxes paid by Americans -- something that Trump has repeatedly, and falsely, denied. In doing so, he noted that the taxing power is clearly a congressional power, not one given to the president, and approving Trump's argument would "neutralize" the separation of powers between the branches.See All UpdatesClose
