US Secretary of State Hillary Clinton, on behalf of the people of the United states has expressed her deep sorrow at the demise of President John Atta-Mills."On behalf of the people of the United States, I want to send my deepest sympathies to the people of Ghana and the friends, family, and loved ones of President John Evans Atta Mills. President Mills made a significant contribution to Ghana’s democracy and development, and forged a strong and positive partnership with the United States."As the third president of modern Ghana, he worked to strengthen his country’s democratic institutions and to expand prosperity for all of its people. He promoted regional peace and reinforced Ghana’s reputation as a leader in Africa. President Mills was a champion for his nation and his loss will be felt around the world. My thoughts and prayers are with all the people of Ghana during this difficult time."
