There might be a little wiggle room, but very, very little wiggle room. trump cannot just ignore the law, or worse yet make up laws that just do not exist. Can you imagine being arrested for breaking a law that does not exist? Well that is what trump is threatening, and beginning to do.Are you saying that once Congress makes a decision to have tariffs, that the President is more or less obligated to execute it?
Congress has expressly delegated some authority to the president to set tariffs. If trump follows those limited powers, he is within the law. It would be legal, but maybe not advicable.State for the record your unequivocal position that the laws passed by Congress do NOT somehow make the establishment of specific tariff rates the domain of Presidential executive proclamation.
Instead, trump is veering into illegal territory. he is just making up laws that do not exist. he could have tried to get Congress to change the laws, but he did not.
