U.S. District Judge Nancy F. Atlas of Texas will be in Jackson to hear arguments by True the Vote organization.
The lawsuit seeks access to nine counties’ voter rolls as Chris McDaniel gathers information to challenge his Republican primary runoff loss to Sen. Thad Cochran.
Plaintiffs say federal law requires authorities to release of voting rolls and poll books without erasing voters’ personal information.
The Mississippi Supreme Court ruled last week that it’s proper to redact birth dates from poll books. McDaniel is asking justices to reconsider.
True the Vote is looking for June 3 Democratic primary voters who illegally crossed over to vote in the June 24 Republican runoff.
