Mayer Brown is backing a new lawsuit against Arizona officials over recent state restrictions on early voting, alleging the laws will make it harder for residents of color to vote.

The federal lawsuit, announced Tuesday and not yet docketed as of publication, features several attorneys from Mayer Brown as well as lawyers with Quarles & Brady and the group Free Speech for People. The complaint is filed on behalf of several groups: Mi Familia Vota, Arizona Coalition for Change, Living United for Change in Arizona (LUCHA) and Chispa Arizona.
