That's a stretch...and even (and thats a huge if) a true terrorist tie was ever established in doesn't even register compared to 911.
FBI set to probe Fort Hood gunman Nidal Hasan's 9/11 links - Times Online
The FBI is set to investigate possible links between the gunman who killed 13 US soldiers at Fort Hood and a radical preacher in contact with at least one of the September 11 hijackers.
Major Nidal Malik Hasan, an army psychiatrist, went on the rampage at the military base in Texas last Thursday.
It has emerged that Major Hasan's family attended the Dar al Hijrah Islamic Centre in Falls Church, Virginia, and that the funeral of his mother, Hanan, was held there on May 31 2001.
At that time the imam of the mosque was Anwar al-Awlaki, a Muslim radical who saw Islam and America as enemies. Interviewed by the FBI after the September 11 terror attacks, Mr Awlaki admitted meeting hijacker Nawaf al-Hazmi several times in San Diego before he moved to Virginia in early 2001. Al-Hazmi was at the time living with Khalid al-Mihdhar, another hijacker. The two Saudi Arabians were on the American Airlines flight that crashed into the Pentagon.
Al-Hazmi and a third hijacker, Hani Hanjour, who piloted the Pentagon crash jet, attended the Dar al Hijrah mosque several times in early April 2001, although Mr Aulaqi has denied meeting them then.
Last night Senator Joe Lieberman called for an investigation into whether the army missed signs that Major Hasan had been turning towards Islamic extremism.
Students on a 2007-2008 master’s programme at a military college revealed yesterday that they had complained to faculty about Major Hasan’s alleged anti-American views.They included him giving a presentation that justified suicide bombing and telling classmates that Islamic law trumped the US Constitution.
“If Hasan was showing signs, saying to people that he had become an Islamist extremist, the US Army has to have zero tolerance,” Senator Lieberman, an independent from Connecticut, told Fox News. “He should have been gone.”
Mr Awlaki, who was born in the US to Yemeni parents, left America in 2002, eventually traveling to his parents' homeland.
He was suspected of links with extremism even before 9/11, being investigated by the FBI in 1999 and 2000 for contacts with a possible procurement agent for Osama bin Laden. During this investigation, the FBI learned that Mr Awlaki knew people involved in raising money for Hamas, a Palestinian group on the US State Department’s terrorist list.
