A war of words between Elon Musk and Donald Trump costs Musk billions.

News: A dramatic public feud between Elon Musk and President Donald Trump on Thursday directly preceded a staggering $26.6 billion hit to Musk's net worth. The controversy, which saw Tesla's stock price tumble by over 14% and its market value shrink by some $150 billion, reportedly ignited over the GOP's proposed tax bill. This legislation includes the controversial removal of electric vehicle tax credits, a provision estimated to cost Tesla $1.2 billion each year. The verbal sparring escalated as Musk leveled accusations against Trump concerning inappropriate affiliations, leading to a public expression of disappointment and criticism from the former president regarding Musk's changed stance.
