Hasan Slated for Hospital Hearing Saturday

Updated 6:30 p.m. Eastern

An attorney for the Army psychiatrist charged in the mass shooting at Fort Hood says his client will have his first court hearing in his hospital room on Saturday.

Maj. Nidal Malik Hasan's civilian attorney, John Galligan, said Friday that military prosecutors notified him of their plans for the hearing at the Brooke Army Medical Center in San Antonio.

Hasan has been recovering there since the Nov. 5 rampage at Fort Hood that left 13 dead and more than 30 wounded. Hasan was shot by civilian members of Fort Hood's police force.

The hearing is to determine whether Hasan will be placed in pre-trial confinement - which usually means jail. But Galligan says he'll argue that Hasan should remain in intensive care because he is paralyzed and still needs hospital care.

Fort Hood officials didn't immediately return a call about the hearing.

On Thursday, Defense Secretary Robert Gates of the circumstances surrounding the Fort Hood shootings.

Meanwhile, a Democratic senator says there may be additional e-mails that could have tipped off law enforcement or military officials to Hasan before he went on his rampage.

Senate Armed Services Committee Chairman Carl Levin said Friday after a briefing from Pentagon and Army officials that his committee will investigate whether those and other e-mails involving Hasan were handled properly.

The government intercepted at least 18 e-mails between Hasan and Anwar al-Awlaki, a radical American- born cleric. They were passed along to two terrorism task forces led by the FBI, but defense officials have said no one at the Defense Department knew about the messages until after the shootings.

Hasan reportedly told Awlaki "I can't wait to join you" in the afterlife in a series of e-mail messages over the last year.

An American official with access to the top secret e-mails told ABC News that Hasan also asked Awlaki, an American-born cleric who has encouraged violence against U.S. soldiers through his Web site, when it's appropriate to conduct jihad and whether killing innocent people was permissible.
