President Bush is appointing a commission to investigate the quality of care at Veterans' Administration hospitals. It will be chaired by former Republican Senator Bob Dole and Donna Shalala, Secretary of Health and Human Services in the Clinton Administration.

Did military and civilian officials ignore early reports? What about other Veterans' Administration facilities? We speak with journalists, doctors and public-policy experts.
