President Donald Trump clashing with the legacy media is nothing new. But the president just took his fight with biased journalists a step too far.

It all began after Trump, hilariously, signed an executive order renaming the Gulf of Mexico the “Gulf of America.” For some reason, the journalists at the Associated Press have stubbornly refused to recognize this name change and are continuing to refer to it as the “Gulf of Mexico” in their coverage. This seems petty and biased, and the Trump administration and its allies have every right to criticize the AP for its choices. But they’re doing more than that.
