“Hurricane Harvey brought terrible destruction — but it also brought out the best in humanity,” Clinton says in the video.

“As former presidents, we wanted to help our fellow Americans begin to recover,” Obama says.

“People are hurting down here, but as one Texan put it, ‘We’ve got more love in Texas than water,’ ” George W. Bush, a former governor of Texas, says.

His father, George H.W. Bush, then says, “We love you, Texas.”

The “One America Appeal” website included information on Harvey recovery efforts and offers ways for people to donate to help victims.

A statement announcing the campaign said it will also plan to help victims of Hurricane Irma ahead of its projected landfall in Florida.

“As the nation carefully watches the advance of Hurricane Irma, the presidents stand ready to expand their appeal to help those affected by that storm,” the statement said.
