First lady Laura Bush gives statement in call center of National Center for Missing and Exploited Children after touring facility on Friday, Sept. 16, 2005 in Alexandria, Va.

U.S. first lady Laura Bush has visited a center for missing children and praised the work of those trying to reunite the families separated by Hurricane Katrina.

Mrs. Bush greeted volunteers at the National Center for Missing and Exploited Children outside Washington Friday.

The center in Alexandria, Virginia says more than 2,000 children are still reported missing from the hurricane or are looking for their parents or other caregivers.

Photographs and information of the missing, including adults, are posted on the center's website.

Some children are only listed by their first name, as their full identification is still unknown, nearly three weeks after the storm hit.

The American Red Cross also has a registry of the missing.
