Elon Musk has reignited his public feud with Bill Gates, calling him a 'liar' in response to recent comments about foreign aid cuts. Musk dismissed claims that reductions in United States Agency for International Development funding have led to deaths, arguing that Gates could use his own resources to address these issues but chooses not to. The exchange follows Gates' earlier criticism of Musk for allegedly endangering vulnerable populations by supporting cuts to foreign aid, which Gates says could increase cases of diseases like measles, HIV, and polio.

Musk, who played a role in government efforts to reduce federal spending, has repeatedly challenged Gates' narrative, accusing him of spreading false information for personal gain. The dispute highlights ongoing tensions between two of the world's most prominent tech leaders over philanthropy, government funding, and responsibility for global health initiatives.
