A federal judge early Saturday temporarily blocked billionaire Elon Musk's government efficiency team from accessing government systems used to process trillions of dollars in payments, citing a risk that sensitive information could be improperly disclosed.

U.S. District Judge Paul Engelmayer in Manhattan issued the order after a coalition of Democratic attorneys general from 19 U.S. states filed a lawsuit late Friday arguing that Musk's Department of Government Efficiency has no legal power to access the U.S. Department of the Treasury systems.

The ruling also applied to other political appointees of President Donald Trump's administration.
