but he heads the state and is responsible for the readiness against such disasters.
when you position a guy who was manager of the national horse riding club ,or something ,as chief of FEMA-Federal Emergency Management Agency
Agency of the US government tasked with Disaster Mitigation, Preparedness, Response & Recovery planning.

as there is a rise in hurricane events and force and it could get worse according to experts.
