The U.S. Justice Department filed a lawsuit Tuesday against the suburb of Eastpointe, Michigan alleging that the city has kept Black residents from having an equal opportunity to elect city council members of their choice.

The DOJ acted in reference to the case of Maurice Walker of Calhoun, Georgia, who was jailed for six nights after police arrested and charged him for the misdemeanor offense of walking under the influence. He was told he could not get out of jail unless he paid the fixed bail amount of $160, according to NBC News.
