Silicon Valley investor Marc Andreessen has shifted his support to Trump following the Biden administration's introduction of uncertainties in AI and cryptocurrency policies, aiming to counter critics of the tech industry. Andreessen had long supported the Democratic Party but has changed his political stance in recent years, becoming a close ally of Trump. This shift was partly due to being sidelined by the Biden administration at the White House last year. Meanwhile, Elon Musk's relationship with Trump has deteriorated, while Andreessen continues to exert influence in Washington through his network of allies in the Trump administration.
