All five living ex-presidents appear at hurricane relief bash -- Trump sends video message

In a rare show of unity, U.S. President Donald Trump praised all five of his living predecessors on Saturday, thanking them in a video for their work helping to raise funds to aid victims of recent hurricanes.

His video statement, which commends Americans for coming together in the wake of four hurricanes and the deadly California wildfires, was shown at Saturday's fund-raising concert for hurricane victims organized by the George H.W. Bush Presidential Library Foundation and former presidents Jimmy Carter, George H.W. Bush, Bill Clinton, George W. Bush and Barack Obama. All five attended the event, which features artists Alabama, Lady Gaga, the Gatlin Brothers, Robert Earl Keene and others.

"The heartbreaking devastation caused by hurricanes Harvey and Irma and Maria and Nate, along with the terrible wildfires in California, have impacted millions of our fellow Americans," Trump said in the video. "As a nation, we mourn for those who died, and we pray for those who lost their homes or their livelihoods."

The former presidents formed the organization "One America" to help with hurricane relief after the storms left devastation and death in Texas, Florida, Puerto Rico and other parts of the U.S. Gulf Coast and Caribbean. The fund has raised more than $31 million for relief.

Obama praised Americans for working to aid neighbors after heartbreaking natural disasters. Obama said the response to the storms showed "the spirit of America at its best - when ordinary people step up and do extraordinary things."

About 11,000 people attended the concert, which was livestreamed on the One America Appeal YouTube channel, theOneAmericaAppeal.org website and the organization's Twitter feed, said Jim McGrath, a spokesman for former President George H.W. Bush as well as One America and the Bush Library.

"These were grievous storms back to back," Clinton said, noting significant work remains to be done.

Dubbed "Deep in the Heart" in a dual reference to the song "Deep in the Heart of Texas" and the idea that Americans' compassion for victims runs deep, the concert is taking place at Texas A&M University in College Station, Texas.
