President Barack Obama will attend a memorial service Tuesday honoring victims of the Ford Hood shootings, an attack he described as "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.

"They are Americans of every race, faith and station. They are Christians and Muslims, Jews and Hindus and nonbelievers," Obama said in his radio and Internet address Saturday, airing the weekend before Veterans Day.
