By BOBBY CAINA CALVAN and MIKE SCHNEIDER FORT MYERS, Fla. (AP) — With the death toll from Hurricane Ian rising and hundreds of thousands of people without power in Florida and the Carolinas, U.S. officials vowed Sunday to unleash a massive amount of federal disaster aid as crews scrambled to rescue people stranded by the storm.Criswell told “Fox News Sunday” that the federal government, including the Coast Guard and Department of Defense, had moved into position “the largest amount of search and rescue assets that I think we’ve ever put in place before.” Still, she cautioned that dangers remain.“Standing water brings with it all kinds of hazards — it has debris, it could have power lines.” More than 1,600 people have been rescued statewide, according to Florida’s emergency management agency.The others involved a man who drowned when his truck plunged into a swamp and another killed by carbon monoxide poisoning from a generator in a garage.___ Associated Press reporters Rebecca Santana in Ft.
