Mrs. Bush made her remarks on the National Public Radio program "Marketplace" after visiting hurricane relief centers in Houston with a delegation that included her husband, former President George H.W. Bush, and former President Bill Clinton.

In a segment at the top of the show on the surge of evacuees to the Texas city, Barbara Bush said: "Almost everyone I’ve talked to says we're going to move to Houston."

Then she added: "What I’m hearing is they all want to stay in Texas. Everyone is so overwhelmed by the hospitality.

"And so many of the people in the arena here, you know, were underprivileged anyway, so this -- this [she chuckles slightly] is working very well for them."

The two former presidents have been chosen by George W. Bush to head fundraising efforts for the recovery. Sen. Hilary Clinton and Sen. Barack Obama were also present during the Houston tour.
