The reason they're now pretending that Musk is an "advisor" is that there are laws against what he proudly says he's doing, and Trump has said Musk is doing.

He can't lead a government department without being confirmed by congress. If he's just an advisor, he and his Musk Youth army can't actually give orders to government employees the way they've been doing, much less fire them.

If someone keeps lying every other breath for years and years, at some point you should stop taking their word at face value.
