Requires the Office to coordinate with other DHS components, the Intelligence Community, and federal, state, local, and tribal authorities, including officials from high-threat areas, state and major urban area fusion centers, and local public health departments where appropriate, and enable such entities to provide recommendations on optimal information sharing mechanisms and on how they can provide information to DHS.
