(FILES) This file photo taken on May 7, 2012 shows former US Secretary of State Colin Powell as he speaks before presenting Britain's Prince Harry the Distinguished Humanitarian Leadership Award during the Atlantic Council 2012 Annual Awards Dinner at a hotel in Washington, DC. Former US secretary of state Colin Powell dubbed Donald Trump a "national disgrace" and an "international pariah" in personal email exchanges hacked and leaked online. The leaked correspondence reveals a stinging indictment of the brash billionaire by a cabinet member in the last Republican president's administration, albeit one who twice endorsed Barack Obama for president. / AFP PHOTO / JEWEL SAMADJEWEL SAMAD/AFP/Getty Images
