The five living former U.S. presidents said Thursday they would team up to raise money for storm recovery efforts.
The announcement by former presidents Barack Obama, George W. Bush, Bill Clinton, George H.W. Bush and Jimmy Carter comes as Texas and Louisiana regroup from Hurricane Harvey and the Atlantic coast is bracing for Hurricane Irma.
The campaign is being called "One America Appeal," and donations can be made at OneAmericaAppeal.org.
Organizers said an account had been established through the George H.W. Bush Presidential Library Foundation to collect and distribute donations. Officials said 100 percent of donations will help hurricane victims. All donations are tax-deductible. Bush, whose presidential library is on the Texas A&M campus, lives part of the year in Houston.
The effort was launched with a public service announcement broadcast on NBC during the Thursday night kickoff of the NFL season.
President Donald Trump tweeted his support.
The appeal is expected to be expanded to help those affected by Irma, which could strike south Florida and the state's Atlantic Coast and then move up into Georgia and South Carolina.
Harvey has caused widespread flooding in Houston and elsewhere and has been blamed for at least 71 deaths, while damaging more than 200,000 homes.
Texas Gov. Greg Abbott has suggested that Harvey's damages could cost up to $180 billion, even more than from Hurricane Katrina in 2005.
