Musk, who also runs SpaceX and a number of other companies, has been known to make big often exaggerated promises. For example, he once called the Hyperloop, which was never built, the "fifth mode of transport" and famously promised to take Tesla private in a Twitter post, saying he had secured financing that he didn't have.

The whole point of the Musk operation is transparency and efficiency in spending taxpayer dollars. Elon Musk is here to stay. And Democrats will just have to deal with it.
