In January 1871, Republican Senator John Scott of Pennsylvania convened a congressional committee to hear testimony from witnesses of Klan atrocities. In February, Republican Congressman Benjamin Franklin Butler of Massachusetts introduced his anti-Klan bill, intended to enforce both the Fourteenth Amendment and the Civil Rights Act of 1866. Butler's bill was narrowly defeated in the House, whereupon Republican Rep. Samuel Shellabarger, of Ohio, introduced a substitute bill, only slightly less sweeping than Butler's original. This bill brought a few holdout Republicans into line, and the bill narrowly passed the House, sailed through the Senate, and was signed into law on April 20 by President Grant. Use during Reconstruction After the Civil War, President Ulysses S. Grant conducted an aggressive—and ultimately successful—campaign against the Ku Klux Klan and its offshoots (such as the Knights of the White Camellia) from the 1860s to the 1870s. Grant deployed federal soldiers to arrest Klan members, enlisted U.S. attorneys to try their cases, supported Congressional legislation like the Ku Klux Klan Act, and organized federal judges to oversee Klan trials. Under the Klan Act during Reconstruction, federal troops, rather than state militias, were used to enforce the law, and Klansmen were prosecuted in federal court, where juries were sometimes predominantly black. Hundreds of Klan members were fined or imprisoned, and habeas corpus was suspended in nine counties in South Carolina. These efforts were so successful that the Klan was destroyed in South Carolina and decimated throughout the rest of the former Confederacy, where it had already been in decline for several years. The Klan was not to exist again until its renewal in 1915. During its brief existence, however, the "first era" Klan did achieve many of its goals in the South, such as denying voting rights to Southern blacks. In its early history, under the Grant Administration, this act was used, along with the Force Act, to bring to justice those who were violating the Civil Rights of newly freed African Americans. After the end of the Grant Administration, and the dismantling of Reconstruction under Rutherford B. Hayes, enforcement of the Act fell into disuse and few cases were brought under the statute for almost a hundred years.
