"This nation will never forget the service of those we lost at Fort Hood, just as we will always honor the service of all who wear the uniform of the United States of America. Their legacy will be an America that is safer and stronger, an America that reflects the courage of the men and women who serve it," said the president.
Mr. Obama left Japan and arrived in Singapore earlier Saturday where he was scheduled to attend meetings with the Asian-Pacific Economic Corporation.
