A federal judge has issued a one-day extension to Florida's voter registration deadline and will hear arguments on a longer extension in a Wednesday hearing.

The order from District Judge Mark Walker is at least a partial victory for Democratic presidential candidate Hillary Clinton.

The initial registration deadline had been Tuesday. But Florida Democrats asked the court to extend the deadline. They argue that would-be voters deserve more time after Republican Gov. Rick Scott urged 1.5 million Florida residents to evacuate last week as Hurricane Matthew approached the U.S. coastline.

Clinton's campaign supported the lawsuit.

The judge's order extends the deadline through 5:00 p.m. Wednesday. He will hear arguments earlier in the day on a longer extension.
