I believe congress is the broken branch of government, and it needs to make many improvements. Congress represents the people of the United States, and in its representation it makes laws to protect their rights,insure there comfort and security. Congress has done a great job job passing laws to protect us. However, many times the house and the senate can not agree with decisions and when they do it's as if their only preference was towards certain people instead of every single individual that is part of this country.
An example of this was the Dream act proposal that was denied by congress a few years ago. This act would allow students to gain permanent residence in the united states. I think congress denied this without considering the fact that this act would help the United States grow as a nation and build a greater society. It could have been denied because of the illegal status of the students or lack of funds for it to be possible, but if this would  been approved we would have a greater america in the future.
 I believe if congress was strong and more united there would have been a solution for immigration long ago.
