If a seat becomes vacant due to resignation, death, or removal, the process for filling that seat is managed at the state level. Specifically, the state governor is responsible for initiating a special election to select a replacement.
Leadership and Impeachment
The House is led by the Speaker of the House, an officer who holds significant influence over the chamber's proceedings.
One of the most critical roles of the House is its involvement in the impeachment process. The House holds the power to impeach, which is the formal act of bringing charges against a federal official. This requires only a simple majority vote to proceed.
Exam Tip: Remember that "impeachment" does not mean removal from office; it is simply the formal accusation. The actual trial and decision on removal happen in the Senate.
The Senate: The Upper Chamber
The Senate serves as a more deliberative body, often acting as a stabilizing force in the legislative process. Its members are subject to stricter requirements and hold unique "advice and consent" powers.
Membership and Vacancies
The qualifications for a Senator are more rigorous than those for a Representative:
- Age: At least 30 years old.
- Citizenship: A U.S. citizen for at least nine years.
- Residency: A resident of the state they are elected to represent.
The process for filling Senate vacancies differs from the House. Generally, the state legislature votes on a replacement. However, if the state legislature is in recess, the state governor has the authority to appoint a replacement to ensure the state maintains its representation.
Leadership and Special Powers
The Senate's leadership structure is unique. The Vice President of the United States serves as the formal head of the Senate. In the event that the Vice President is absent, the President Pro Tempore presides over the chamber.
Beyond standard lawmaking, the Senate possesses "special powers" that the House does not:
- Approving Appointments: The Senate must approve major presidential appointments (such as Cabinet members or judges) via a majority vote.
- Treaty Approval: The Senate has the power to approve international treaties, but this requires a higher threshold of a 2/3 vote.
The Senate's Role in Impeachment
While the House initiates impeachment, the Senate acts as the court. The Senate conducts the formal trial of the impeached official. To convict and remove an official from office, a supermajority of a 2/3 vote is required.
The Legislative Process and Revenue
The interaction between the two chambers is governed by specific rules regarding how laws are drafted and passed. A key distinction involves the origin of certain types of legislation.
Revenue Bills
Not all laws can start in either chamber. According to the Constitution, all Revenue Bills—legislation that deals with taxation and the raising of money—must originate in the House of Representatives. This ensures that the chamber most directly accountable to the people has the primary say in how they are taxed.
Summary of Congressional Roles
To visualize the division of labor, consider the following breakdown of responsibilities:
| Feature | House of Representatives | Senate |
|---|
| Min. Age | 25 | 30 |
| Citizenship | 7 Years | 9 Years |
| Vacancy Filled By | Governor (Special Election) | State Legislature (or Governor if in recess) |
| Impeachment Role | Impeaches (Majority Vote) | Conducts Trial (2/3 vote to convict) |
| Key Powers | Originates Revenue Bills | Approves Treaties (2/3) & Appointments (Majority) |

Through this bicameral structure, the U.S. government ensures that no single body has absolute control over the creation of law, the taxation of citizens, or the removal of high-ranking officials.
