"The stark and tragic images of human suffering in the aftermath of Hurricane Katrina have reminded us yet again that civil rights and equal rights are still the great unfinished business of America. The suffering has been disproportionately borne by the weak, the poor, the elderly and infirm, and largely African-Americans, who were forced by poverty, illness, unequal opportunity to stay behind and bear the brunt of the storm's winds and floods. I believe that kind of disparate impact is morally wrong in this, the richest country in the world."
