United States Chambers of Congress

  The United States Congress is made up of majority party exerting substantial influence over lawmaking. But even though one chamber may pass a law with no trouble, it doesn't always mean the other will.  Two advantages the majority party in the United States House of Representatives has in lawmaking, is the Speaker of the House, and how the work of the House is usually done in committees, which are full of members from the House in each committee, hence giving more power and say to the House of Reps.  The House is so full of power, as they control Congress's agenda, most committee chairs, and when and where things happen with lawmakers and members of Congress.
  The House and Senate both hold different powers which makes it less likely for a law to be passed by the other.  In the Senate, they are able to filibuster laws, causing a bill from the House to be knocked down.  The House on the other hand has a "rule committee" in which they are able to debate and then kill a bill.  Many bills go through this back and forth process and are sometimes knocked down, and revised multiple times before they make it to the Executive Branch for the President's signature. 
  A filibuster allows the Senate to kill a law that the House passed on its way to the Executive Branch.  Also, a germaneness occurs after the House's "rule committee" denies a bill so the Senate adds to the bill and then sends it back, yet the House once again doesn't agree to pass it and there filibusters it.
