U.S. Sen. Bill Nelson has filed a revised "friend of the court" brief for a challenge to key provisions of Florida's new election.
The Florida Democrat filed his new brief Friday with the U.S. District Court in Washington.
The court rejected his first filing on June 14, saying it was too late to introduce new evidence in the case. The new version is confined to arguments based on the law and existing evidence.
Nelson and other opponents contend the Republican-sponsored law discriminates against minorities, young people and the elderly who tend to vote Democratic.
The court is considering provisions that reduce early voting days and put new restrictions on registration drives and voters who change out-of-county addresses at the polls on Election Day.
