Exactly the day after 9-11 Donald Rumsfeld announced that the financial audit of the Pentagon could not account for 2.3 Trillion dollars. It was essentially missing. Rumors claimed that it was just an accounting error. If it was, it was monumental.

Musk and Ramaswamy want to reduce waste and redundancy in government spending and remove regulations that slow down billionaires' projects.

Perhaps they only want to tweet about waste and missing money. Going after the black budget of the Pentagon seems like a naive thing to do.
I believe that putting the squeeze on the military would be a fool's errand. But what if they succeed and find the missing money beyond $500 toilet seats?
