The House voted Tuesday to increase oversight of the National Security Council if it gets larger than 100 people, in an attempt to crack down on White House micromanagement of the military that has drawn complaints from previous defense secretaries.

The proposal passed by voice vote as an amendment to the National Defense Authorization Act, and it was offered by House Armed Services Committee Chairman Mac Thornberry, R-Texas. The language would also require the head of the president’s advisory board to be confirmed by the Senate, and testify before Congress if the National Security Council grows too large. Thornberry said an NSC that gets too big will end up directing military operations, not just advising.
