Bilingual Education In California --NPR's Ann Cooper reports from the United Nations that Cambodia's seat in the General Assembly will remain empty for now. The confusion and controversy springs from the coup led by Hun Sen two months ago that ousted the country's democratically elected leader. The problem led to fierce debate among the U-N's Credentials Committee. The U-S didn't want to recognize Hun Sen, but Russia and China pushed to seat one of his representatives. Now Hun Sen says he plans a trip to New York to demand the seat be given to his government.
