“We have in past years raised about $12 million a year and are up over $137 million that we’ve been able to give away to charities many of whom don’t have the opportunity to raise money in any other way,” Edie Lutnick, who runs the relief fund, said. “We took our lessons from 9/11 and from our successful relief efforts in Sandy, and in Moore, Oklahoma, and we’re doing it again with Harvey and as things progress with Irma, there as well.”
