Politicians lying is so common it's a cliche. Trump does it in an unusual way, because they typically lie about what they're going to do and then you don't find out until after they're in office, whereas Trump will say inaccurate things you can contemporaneously validate.

He'll do things like call Kamala Harris the "border czar", which she never had as an official title, but she was actually tasked with handling some aspects of the migrant issue. So then it's not exactly accurate, but to write a story about it, now you're writing a story about immigration (which Trump wants) and explaining the issue by telling people that Harris really was tasked with doing something about it, with the implication that it's not solved. He's clearly doing it on purpose. It's one of the reasons the news media hates him so much. He's effectively manipulating them and they don't like it.

But then, for example, in the Trump interview with Elon Musk, Musk proposed a government efficiency commission and Trump was receptive to the idea. Which isn't a bad idea at all, but that was not the focus of any of the interview coverage I observed.

Trump's strategy (whether one exists or not) around this aside, heaps of people have been called the "X czar" by the media for decades. As you point out, it's a shorthand for someone in the presiding administration who is tasked with some singular objective. Rarely did their official title ever contain the word "czar".

The current media "fact check" circus around Harris never having been the border czar is yet another clearly identifiable example of a class of people who were so dismayed by Trump's presidency that they would go to any length, however distasteful, to prevent a second term.
