One of the issues is the Sioux tribe in the Black Hills. The Black Hills are public land but are considered sacred by the Sioux tribes. The Black Hills and other lands were set aside for the Sioux in an 1868 treaty. But Congress passed a law in 1877 taking the land. It was originally their land, it is sacred to them, the US agreed to set it aside for them, Congress took it from them. Wouldn’t it be the right thing to do to give it back to them?
