On June 5, 2019, U.S. President Trump and tech giant Elon Musk went from allies to open confrontation. The two sides intensified their conflict over the tax reform bill, with Trump accusing Musk of going 'crazy' due to the cancellation of electric vehicle subsidies, and threatening to terminate his government contracts; Musk retaliated by saying the bill 'was not consulted' and supported Trump's impeachment, even announcing that SpaceX would retire the key crewed spacecraft 'Dragon'. On that day, Tesla's stock plummeted 14%, evaporating over $150 billion in market value. This conflict stemmed from Musk's strong opposition to Trump's 'big and beautiful' plan, which was criticized for 'robbing the poor to pay the rich' and increasing government debt. Analysts pointed out that Musk, who spent $259 million helping Trump win the election, has now completely turned against him due to political returns not meeting expectations.
