The U.S. Agency for International Development’s director of security and his deputy were placed on administrative leave Saturday after they tried to prevent employees from the Department of Government Efficiency from accessing secure USAID systems, five sources familiar with the events told NBC News.

The USAID systems the DOGE team tried to access included personnel files and security systems, including classified systems beyond the security level of at least some of the DOGE employees, according to three of the sources. The systems also included security clearance information for agency employees, two of the sources said.

“No classified material was accessed without proper security clearances,” Katie Miller, who worked in President Donald Trump’s first administration and has since joined DOGE, said Sunday on X.
