Didn't there used to be posts on FR that FEMA is going to take control of the United States?
Probably after they saw the X-Files movie, LOL!
Actually in the 'old days', like when it was first created, they could - FEMA had the ultimate power and control in a National Disaster. It was pretty scary in the 'legal' power they had and what they could do. (relocation camps being one)
But then Willard changed it slightly with an EO by having 'his' AG Janet Rino having ultimate control over FEMA and then when the Homeland Security Dept was created FEMA was merged into that and became a subservient division.
