By 1875, Redeemer Democrats had taken control of all but three Southern states. As violence against black Southerners escalated once more, Grant's Attorney General Edwards Pierrepont told Republican Governor Adelbert Ames of Mississippi that the people were "tired of the autumnal outbreaks in the South", and declined to intervene directly, instead sending an emissary to negotiate a peaceful election. Grant later regretted not issuing a proclamation to help Ames, having been told Republicans in Ohio would bolt the party if Grant intervened in Mississippi. Grant told Congress in January 1875 he could not "see with indifference Union men or Republicans ostracized, persecuted, and murdered." Congress refused to strengthen the laws against violence, but instead passed a sweeping law to guarantee blacks access to public facilities. Grant signed it as the Civil Rights Act of 1875, but there was little enforcement and the Supreme Court ruled the law unconstitutional in 1883. In October 1876, Grant dispatched troops to South Carolina to keep Republican Governor Daniel Henry Chamberlain in office.
