The United States military removed or restricted Donald Trump's access to nuclear launch codes during his presidency.

Caveats

• The only evidence supporting the claim comes from a single book excerpt reporting Gen. Milley's informal directive, which multiple expert sources characterize as legally unauthorized and not constituting a formal restriction.
• No legal mechanism exists for the U.S. military to remove or restrict a sitting president's nuclear launch authority — any such action would be extralegal.
• The claim conflates an informal, reportedly unauthorized personal action by one general with a systemic or institutional restriction on presidential nuclear access.
