A key U.S. senator called Sunday for an investigation into whether the Army missed signs that the man accused of opening fire at Fort Hood had embraced an increasingly extremist view of Islamic ideology.
Sen. Joe Lieberman's call came as word surfaced that Maj. Nidal Malik Hasan apparently attended the same Virginia mosque as two Sept. 11 hijackers in 2001, at a time when a radical imam preached there. Whether Hasan, an Army psychiatrist, associated with the hijackers is something the FBI will probably look into, according to a law enforcement official who spoke on condition of anonymity because the investigation is ongoing.
Classmates participating in a 2007-2008 master's program at a military college complained repeatedly to superiors about what they considered Hasan's anti-American views. Dr. Val Finnell said Hasan gave a presentation at the Uniformed Services University that justified suicide bombing and even told classmates that Islamic law trumped the U.S. Constitution.
Lieberman, chairman of the Senate Homeland Security and Governmental Affairs Committee, wants Congress to determine whether the shootings constitute a terrorist attack.
"If Hasan was showing signs, saying to people that he had become an Islamist extremist, the U.S. Army has to have zero tolerance," Lieberman, an independent from Connecticut, said on "Fox News Sunday." "He should have been gone."
Authorities continue to refer to Hasan, 39, as the only suspect in the shootings that killed 13 and wounded 29, but they won't say when charges would be filed. They have not revealed a possible motive. Hasan, who was shot by civilian police to end the rampage, was in critical but stable condition at an Army hospital in San Antonio.
He was breathing on his own after being taken off a ventilator on Saturday, but officials won't say whether Hasan can communicate. Sixteen victims remained hospitalized with gunshot wounds, and seven were in intensive care.
Army Chief of Staff George Casey warned against reaching conclusions about the suspected shooter's motives until investigators have fully explored the attack. "I think the speculation (on Hasan's Islamic roots) could potentially heighten backlash against some of our Muslim soldiers," he said on ABC's "This Week."
A government official speaking on condition of anonymity because the person was not authorized to discuss the case said an initial review of Hasan's computer use has found no evidence of links to terror groups or anyone who might have helped plan or push him toward the attack. The review of Hasan's computer is continuing, the official said.
