As President-elect Donald Trump’s list for secretary of state grows, so do questions about others in his national security team. Specifically, the number of generals Trump is surrounding himself with.

Trump has named two retired generals to his team: Michael Flynn as national security adviser and James Mattis as defense secretary. Two other retired generals and a retired admiral are being considered for national security team positions.

The specific issue is Mattis retired from the Marine Corps in March 2013. U.S. law requires seven years of separation from active duty for any secretary of defense. For Mattis to be appointed, Congress would need to waive the requirement.

The U.S. Constitution empowers the President of the United states with the duties of Commander-in-Chief, ensuring civilian control of the military and the government. How might the presence of top military brass in the cabinet room impact the Trump administration?
