Sen. Bill Nelson is expressing concern as the National Flood Insurance Program reportedly has denied payments on some 90 percent of claims after Irma.
Nelson also raised alarm that a top leader of the National Flood Insurance Program once worked as an executive for a subcontractor accused of low-balling claims after Superstorm Sandy.
The central Florida Democrat expressed the concerns in a letter to the top administrator of the Federal Emergency Management Agency.
He called for more details on new safeguards aimed at protecting flood insurance claims from fraud after a busy hurricane season that has included Harvey, Irma, Maria and Nate.
The Palm Beach Post reports some $72 million in payments have been made on flood insurance claims. Many more claims remain. Only 8 percent have been resolved.
