Elon Musk is leaving his job as an important helper for President Donald Trump. He did not reach his big goals to change the government and spend less money. During his time, many people lost their jobs and some government groups were made smaller. At first, Musk wanted to save $2 trillion, but then he only saved $150 billion. This made other people in the government unhappy. Musk is leaving because he said that Trump's plans to spend money will make the country owe more money. The government will still try some of Musk's ideas to save money. But Musk is not happy with how the government works, and he will spend less money on politics.
