Answer
The amendment was established after the senate was accused of high levels of corruption.
Explanation
The 17th amendment gives a further definition on how senators are elected. Before the 17th amendment the senate was place for millionaires, individuals who acquire seats through bribing their way to the post. This is because the corrupt state legislatures were the political institutions responsible for senators’ election. The institutions were corrupt thus the notorious and incompetent individuals bought their way into senate. The 17th amendment solved this challenge where the senate of the United States was made to be composed of two Senators, the constitutional state and the other elected by the people.
