In an effort to slash government spending, President Trump has asked the world’s richest man, Tesla CEO Elon Musk, to lead his Department of Government Efficiency (DOGE). In turn, Musk and his team have spent the first few weeks of Trump’s second term waging a largely unchecked war on the federal bureaucracy.

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.
