Mustafa Ahmed Adam al-Hawsawi, originally from Saudi Arabia, has been charged with conspiracy to commit terrorism, attacking civilians and civilian objects, murder in violation of the laws of war, destruction of property in violation of the laws of war, hijacking, terrorism, and providing material support for terrorism. The government has elected to try al-Hawsawi with four other detainees, all of whom are alleged to have been directly involved in the planning and execution of the September 11 terrorist attacks; the Defense Department is seeking the death penalty for all of them. The government claims that al-Hawsawi helped research flight schools for the 9/11 terrorist attacks and administered bank accounts for several of the hijackers.

Although al-Hawsawi was reportedly arrested and transferred to US custody in March 2003, he was not transferred to Guantanamo until September 2006. In the interim he was held incommunicado in secret CIA detention facilities, where he was effectively "disappeared."

Al-Hawsawi has not yet formally accepted counsel, but lawyers acting on his behalf have contested his mental capacity to stand trial.

On November 13, 2009, the Obama administration announced that al-Hawsawi would be transferred to federal court in New York for prosecution.
