Under a new White House executive order signed on Monday, U.S. defense contractors will be required to conduct a comprehensive review of their critical supply chains to identify any sources of supply originating from adversary nations.

"This falls under defense readiness. If a missile system relies on suppliers controlled by foreign entities, the Department of Defense must thoroughly assess the situation well before hostilities begin," President's senior trade adviser Peter Navarro told reporters.

President Trump signed this executive order, directing Defense Secretary Pete Hegseth to initiate procedures requiring contractors to conduct a comprehensive review of critical supply chains.
