Why are Elon Musk and Donald Trump fighting?

President Trump and Elon Musk's collaboration has officially ended as their former relationship soured over a $1 trillion pork-filled Congressional spending bill. The controversial bill, which included deep cuts to federal programs like Social Security and healthcare, further alienated the two figures amid heated public backlash. Trump criticized Musk publicly after his vote on the legislation, accusing him of "wearing thin" in their exchanges, while his support from tech billionaires has also created turmoil within the industry, potentially harming the tech sector as a result.
