Al-Marri has been held in a Navy brig outside Charleston, S.C. for more than 5 years since President George W. Bush declared him an enemy combatant.

He will now be transferred to Illinois to face trial in a civilian court on charges of providing material support to terrorism.

Before the indictment, the Al-Marri case was headed to the Supreme Court.

The court is considering whether the president has the authority to order the arrest of terror suspects in the United States and hold them indefinitely without bringing charges.
