Allies of Donald Trump are frustrated with Elon Musk after he questioned a $500 billion AI investment pledge from tech CEOs, which Trump announced at a press conference. Musk dismissed the commitment on social media, claiming that the funds are not secured. This has sparked discontent among Trump's inner circle, who feel that Trump lacks leverage over Musk, who seems indifferent to their concerns. Trump downplayed the criticism, attributing it to Musk's rivalry with Sam Altman.
