FWIW, you're thinking about the DoD/the Pentagon, not the federal government as whole - and yeah, the Pentagon hasn't been able to pass an audit in ~6 years.
The defense budget is somewhat more opaque, though, for national security reasons. I don't know if they are good reasons or not, but that's the story at least.
Why would you trust the man who's been heavily subsidized by the government to do an audit? A significant chunk of Elon Musk's money came from government contracts his companies had with the US government.
Exactly — this isn’t good will. The only subsidies he cares about are his own. Though all involved don’t seem bright enough to realize that destabilizing the government, its finances and the perception of the dollar will have consequences for their own wealth.
It’s hard to pass an audit when unfettered access has been granted to a billionaire without access and cronies installing unauthorized software and strong arming everyone they encounter.
