They are violating multiple laws. The Administrative Procedure Act (APA) of 1946 contains the rule that prevents the U.S. executive branch from acting in an arbitrary and capricious manner. The reason for this law is so that Government operates in a steady and understandable way and doesn't have dramatic shifts due to a change in the Executive branch. Having this law allows for things like a stable society. That in turn build trust resulting in things like our stock market being a goto not just for Americans but investors all over the world. It allows for the trust in the US Government needed for our bonds to be considered safe investments. It allows for the trust in the US Government needed for the dollar to be used as the world reserve currency. Donald Trump already lost in the Supreme Court his last term doing these sorts of arbitrary and capricious executive actions but he doesn't care that it's not only unconstitutional but also undermines the United State position as number one in the world order.
