WASHINGTON, Sept. 6 - As President Bush battled criticism over the response to Hurricane Katrina, his mother declared it a success for evacuees who "were underprivileged anyway," saying on Monday that many of the poor people she had seen while touring a Houston relocation site were faring better than before the storm hit.

"What I'm hearing, which is sort of scary, is they all want to stay in Texas," Barbara Bush said in an interview on Monday with the radio program "Marketplace." "Everyone is so overwhelmed by the hospitality."

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

Mrs. Bush toured the Astrodome complex with her husband, former President George Bush, as part of an administration campaign throughout the Gulf Coast region to counter criticism of the response to the storm. Former President Bush and former President Bill Clinton are helping raise money for the rebuilding effort.

White House officials did not respond on Tuesday to calls for comment on Mrs. Bush's remarks.
