The outreach workers known as navigators won't be allowed to help people sign up for health insurance on the grounds of county health departments, according to a memo from the Florida Department of Health. The order from Deputy Health Secretary C. Meade Grigg went out late Monday to the 60 local health department directors across the state. Grigg declined to comment on the directive. But health department spokeswoman Ashley Carr said there was a need for "clarity" and "a consistent message" across the agency.
