Before heading to the polls, it’s important for voters to understand what responsibilities actually belong to the offices appearing on the ballot. U.S. senators help shape federal laws and national policy, but there are also many areas people commonly assume they control that actually belong to state governments, local officials, courts, or federal agencies. This guide is intended to give voters a straightforward look at what a U.S. senator does — and what responsibilities fall outside the office’s authority — so citizens can make informed decisions during election season.

WHAT A U.S. SENATOR DOES

1. Writes and Votes on Federal Laws

U.S. senators introduce, debate, amend, and vote on legislation affecting the entire country.

These laws can involve:

• Taxes
• National defense
• Immigration
• Healthcare
• Energy policy
• Agriculture
• Interstate commerce
• Federal spending

The Senate shares lawmaking responsibilities with the U.S. House of Representatives.

2. Represents an Entire State in Washington, D.C.

Unlike members of the House, who represent congressional districts, each U.S. senator represents their entire state.

This includes:

• Meeting with residents and local leaders
• Advocating for statewide priorities
• Communicating with constituents about federal issues

Each state elects two senators to six-year terms.

3. Votes on the Federal Budget and Spending Bills

Senators help decide how federal taxpayer dollars are spent through appropriations and budget legislation.

This includes funding for:

• Defense
• Transportation
• Disaster relief
• Federal agencies
• Healthcare and social programs

4. Serves on Senate Committees

Much of the Senate’s detailed work happens in committees, where senators:

• Review legislation
• Hold hearings
• Question witnesses
• Debate policy proposals
• Recommend changes to bills before they reach the Senate floor

5. Confirms Presidential Appointments

One responsibility unique to the Senate is confirming many presidential appointments, including:

• Federal judges
• Supreme Court justices
• Cabinet secretaries
• Ambassadors

These confirmations are part of the Senate’s constitutional “advice and consent” role.

6. Votes on Treaties

The Senate has the authority to approve or reject treaties negotiated by the president.

Treaties require a two-thirds Senate vote for ratification.

7. Participates in Oversight of the Federal Government

Senators help oversee how federal agencies operate and how taxpayer money is spent.

This can include:

• Investigations
• Hearings
• Requests for information
• Agency oversight

8. Assists Constituents With Federal Agencies

Senate offices often help residents navigate issues involving:

• Veterans benefits
• Social Security
• Passports
• Immigration paperwork
• Federal agencies and programs

9. Participates in Impeachment Trials

When the House impeaches a federal official, the Senate conducts the trial and votes on conviction or removal from office.

WHAT A U.S. SENATOR DOES NOT DO

Because U.S. senators regularly participate in national debates involving taxes, immigration, healthcare, defense, and the economy, it’s common for voters to associate a wide range of responsibilities with the office. In reality, many government functions are divided among federal, state, and local levels, and responsibilities often overlap in ways that can be difficult to follow. The following section is intended to help clarify what authority a U.S. senator actually has under federal law.

1. A U.S. senator does not make laws alone.

Bills must pass both the Senate and House and usually require the president’s signature.

2. A U.S. senator does not control state or local governments.

Cities, counties, and states govern themselves through their own elected officials.

3. A U.S. senator does not directly run federal agencies.

Federal agencies are managed by the executive branch under the president.

4. A U.S. senator does not decide court cases or criminal verdicts.

Those decisions belong to the judicial branch.

5. A U.S. senator does not control local schools or school districts.

Local school boards and state education departments oversee schools.

6. A U.S. senator does not personally control inflation, gas prices, or grocery prices.

Economic conditions are influenced by markets, global events, federal policy, and many other factors.

7. A U.S. senator does not personally approve individual federal benefits.

Programs like Social Security and veterans benefits follow federal laws and agency rules.

8. A U.S. senator does not oversee local roads, utilities, or city services.

Those responsibilities belong to local and state governments.

9. A U.S. senator does not command the military.

The president serves as Commander in Chief.

10. A U.S. senator does not have authority outside the federal government.

The office pertains to federal law and national policy, not state or local governance.

Understanding what powers belong to U.S. senators — and what responsibilities fall outside their authority — helps voters better understand how the federal government functions and how national laws are made. As election season continues, guides like this are intended to provide clear, factual information so voters can make informed decisions at the ballot box.
