Summary

The Department must have a seal that the President approves. The Secretary can use the same powers to involve members of the armed forces that the Transportation Secretary has. Unless a law or specific order says otherwise, duties given here can be passed down to subordinates. If a state or local law enforcement official asks, the Secretary can send the Secret Service or ICE to help investigate violent acts in public places, shootings, and mass killings. That help is treated as federal work. "Mass killings" means three or more deaths in one incident. "Place of public use" is defined elsewhere in federal law.
