Which of the following is the strongest constitutional argument for the authority of the President to take action in these circumstances requiring the governor of Aurora to release the Aurora prisoner?

The power of the President to negotiate with foreign nations impliedly authorizes the President to make executive agreements with them which prevail over state law.
