From ABC News:
U.S. intelligence agencies were aware months ago that Army Major Nidal Hasan was attempting to make contact with people associated with al Qaeda, two American officials briefed on classified material in the case told ABC News.
Hasan, accused of murdering 13 and wounding 29 at Ft. Hood, Texas, last Thursday, reportedly shouted “Allahu Akbar!” before he began shooting; visited websites associated with Islamist violence; wrote Internet postings justifying Muslim suicide bombings; considered U.S. forces the enemy; opposed American involvement in Iraq and Afghanistan as wars on Islam; advocated beheading nonbelievers; and told a neighbor shortly before the shootings that he was going “to do good work for God.” Now, we learn he was trying to contact people associated with al Qaeda.
On Friday, President Obama cautioned the public “against jumping to conclusions” about the killings. In his weekly address Saturday, the president declared that “we cannot fully know” Hasan's motives, and instead used the address to celebrate diversity in the United States armed forces.
