U.S. Rep. Corrine Brown and others are asking a judge to block a law that reduces early voting days.
A federal judge on Wednesday will consider the request from the Jacksonville Democrat, the Duval County Democratic Party and the Southern Christian Leadership Conference.
Brown and others contend the law passed by the Republican-controlled Legislature that cut the number of days from 14 days to eight days discriminates against blacks because they vote early in large percentages.
Secretary of State Ken Detzner is defending the new law as are Republican leaders from several counties.
Lawyers for Detzner say that Brown has not proven that the law harms minorities since early voting is still available.
They also criticized Brown for bringing the lawsuit on the eve of an election.
