It is not known whether the intelligence agencies informed the Army that one of its officers was seeking to connect with suspected al Qaeda figures, the officials said.

One senior lawmaker said the CIA had, so far, refused to brief the intelligence committees on what, if any, knowledge they had about Hasan’s efforts…

Investigators want to know if Hasan maintained contact with a radical mosque leader from Virginia, Anwar al Awlaki, who now lives in Yemen and runs a web site that promotes jihad around the world against the U.S.

In a blog posting early Monday titled “Nidal Hassan Did the Right Thing,” Awlaki calls Hassan a “hero” and a “man of conscience who could not bear living the contradiction of being a Muslim and serving in an army that is fighting against his own people.”
