Obama had been scheduled to arrive in Asia on Thursday. But a source familiar with Obama's planning says the president will arrive in Tokyo a day later than expected. The source spoke on condition of anonymity because the White House plans to release a revised schedule in the coming days.
In his Saturday radio and Internet address, the president called the attack "all the more heartbreaking and all the more despicable" because it occurred on the nation's largest Army post.
He praised those who ended the shootings, which killed 13 and wounded 30 others. And he lauded the armed services' diversity -- a move designed to calm tensions about the suspected shooter, Maj. Nidal Malik Hasan.
After the address aired, Obama talked about the Fort Hood shootings during a closed-door meeting with House Democrats on health care.
