WASHINGTON - "Dirty Bomb" suspect Jose Padilla has been indicted on criminal charges in Miami, according to an indictment unsealed Tuesday. Attorney General Alberto Gonzales was expected to discuss the indictment at a news conference in Washington. Padilla, a Brooklyn-born Muslim convert, has been held as an "enemy combatant" in Defense Department custody for more than three years. The Bush administration had resisted calls to charge and try him in civilian courts. The indictment avoids a Supreme Court showdown. Padilla's lawyers had asked justices to review his case last month, and the Bush administration was facing a deadline next Monday for filing its legal arguments.
