In one short, succinct statement Justice George Sutherland altered the relationship between Congress and the executive branch. “The President [operates] as the sole organ of the federal government in the field of international relations,” he wrote in the United States Supreme Court’s decision of U.S. v.

This idea of letting territories vote on whether or not they wanted slavery was supposed to be helpful in solving the issue of slavery in the United States. However, this led to terrible violence and bloodshed, especially in Kansas. After Kansas voted to become a slave state, many anti-slavery individuals claimed the election was rigged due voters coming from Missouri to vote in the Kansas election. This resulted in fighting between the two. This period is now known as "Bleeding Kansas." This idea was one of many solutions that failed to solve the issue of slavery in America.
