Elon Musk, head of the US government's Department of Efficiency, has accused the US Agency for International Development (USAID) of funding the development of biological weapons. "Did you know that USAID used your tax dollars to fund the development of biological weapons, including novel coronavirus, that killed millions of people," he wrote on social platform X. Musk previously said he considered USAID to be a "damn" criminal organization. The Associated Press quoted sources as saying that two USAID security chiefs were placed on administrative leave for clashing with the Department of Government Efficiency - who refused to provide classified information to Musk's department.
