Today President Clinton will sign the Welfare Bill, ending 60 years of federal guarantees of aid to the poor. In so doing, he has outraged a number of his traditional constituencies: unions, women, immigrants, religious groups and children’s advocates. Marion Wright Edelman, head of the Childrens Defense Fund and a personal friend of the Clintons released a scathing condemnation of the President yesterday, calling the bill “the biggest betrayal of children and the poor since the Childrens Defense Fund began. She added “this act will leave a moral blot on his presidency and on our nation that will never be forgotten.”
