U.S. Secretary of Defense Donald Rumsfeld is saluted as he boards USS Essex to speak with sailors and Marines at Changi Naval Base in Singapore June 4, 2004. Rumsfeld is in Singapore to meet Asian defence ministers. Rumsfeld said on Friday he regretted the surprise resignation of CIA director George Tenet, calling him "an enormously talented public servant". Tenet, who presided over intelligence lapses involving the September 11, 2001, attacks and the failure to find weapons of mass destruction in Iraq, will leave in July, the Bush administration announced on Thursday.
