Powers of the House and Senate

Each house of Congress has the power to introduce legislation on any subject except revenue bills, which must originate in the House of Representatives. The large states may thus appear to have more influence over the public purse than the small states. In practice, however, each house can vote against legislation passed by the other house. The Senate may disapprove a House revenue bill -- or any bill, for that matter -- or add amendments which change its nature. In that event, a conference committee made up of members from both houses must work out a compromise acceptable to both sides before the bill becomes law.

The Senate also has certain powers especially reserved to that body, including the authority to confirm presidential appointments of high officials and ambassadors of the federal government as well as authority to ratify all treaties by a two-thirds vote. Unfavorable action in either instance nullifies executive action.

In the case of impeachment of federal officials, the House has the sole right to bring charges of misconduct that can lead to an impeachment trial. The Senate has the sole power to try impeachment cases and to find officials guilty or not guilty. A finding of guilt results in the removal of the federal official from public office.

In addition, the Constitution specifically forbids certain acts by Congress. It may not:
