TALLAHASSEE, Fla. (AP) - Republican Gov. Rick Scott has signed a new Florida law that critics say will discourage likely Democratic voters from registering or casting ballots.

Sponsors in the GOP-controlled Legislature argued the law Scott signed Thursday will prevent election fraud.

The law may be reviewed by the U.S. Department of Justice to determine if it discriminates against minority voters. Opponents also say they are considering court challenges.

The law reduces early voting hours. It also requires voters who make address changes at the polls to cast provisional ballots that may not be counted.

The League of Women Voters has decided to halt voter registration drives in Florida due to new requirements the law puts on such activities.

The legislation passed largely along party lines.
