The idea of giving politicians free license to say what they want, then occasionally "fact checking" them is predicated on the idea that they are not primarily liars but sometimes err or bend the truth or even lie on occasion but as an exception to the rule.
Donnie is the most thoroughly documented liar in all of works history, and other republicans try to emulate him, or at the very least, echo and amplify his lies. It's horrendous journalism to give a platform to known and obvious liars.
Saying "but he's the president" doesn't mean you have to give him so much free airtime, especially if he's largely given a pass for all his lying and tyranny and violations of law.
He should constantly be referred to as our first and only convicted felon, and the biggest liar ever. Then *in that context* it should be reported that he lied yet again, and then tell the truth about his topic, and only then report his actual lie, then finally close with the truth again.
If he lies and says we have evidence that the moon is made of geeen cheese, the story is that the president of the United States lied. His statement about the moon and green cheese is a detail of the story providing evidence that he in fact lied.
Instead the media simply parrots his lies and says some democrats disagree. This allows republicans to weaponize their lies and turn actual truth into a partisan viewpoint.
