What is concerning about Trump's ban on the Associated Press over the Gulf naming issue?

Trump's ban on the Associated Press for not calling the Gulf of Mexico the 'Gulf of America' reveals a deeply troubling approach to press freedom. What's particularly alarming is Trump's claim that the AP isn't 'following the law' - as if a president can unilaterally mandate terminology and make it legally binding. This authoritarian attitude toward media represents a chilling vision of how Trump believes presidential power should work. Rather than recognizing established geographic definitions or respecting press independence, he's attempting to use access to the Oval Office and Air Force One as leverage to force compliance with his arbitrary declarations, undermining fundamental democratic principles of press freedom.
