American-born terror suspect Jose Padilla is expected to plead innocent Friday to charges of belonging to a terrorist cell.
Lawyers for Mr. Padilla are expected to ask a Miami, Florida, court that he be released on bail. Prosecutors say they will oppose that request.
Mr. Padilla was held in a military prison for more than three years without charge before his move to the civilian court system on Thursday. The U.S. Supreme Court agreed this week to let the Bush administration transfer him, changing his status from what the White House calls "an enemy combatant" to a regular criminal suspect.
The Supreme Court will still consider whether Mr. Padilla's earlier detention was legal.
He was arrested on suspicion of plotting to set off a radioactive "dirty" bomb within the United States. But an indictment revealed in November makes no mention of that charge.
