Opening question

How does the president's power to reject a law work, and how can Congress respond to that rejection?

Teacher brief

The veto is the president's constitutional power to reject a bill passed by Congress. However, Congress can override this veto with a two thirds majority vote in both the House and the Senate, allowing the bill to become law despite the president's objections.

Background for discussion

In the United States government, the president has the authority to veto legislation passed by Congress. This means the president can refuse to sign a bill into law and send it back to Congress with reasons for the rejection. The veto serves as a check on legislative power, ensuring that the president can prevent laws they believe are not in the nation's best interest. However, the Constitution also provides Congress with a way to counter this power. If both the House of Representatives and the Senate each vote by a two thirds majority to override the veto, the bill becomes law without the president's approval. This process balances the powers of the executive and legislative branches, encouraging cooperation and compromise.

Real-world example

Imagine Congress passes a bill to improve public parks. The president disagrees and vetoes it, believing the bill is too costly. Congress then debates and holds a vote. If two thirds of both chambers vote to override the veto, the bill becomes law despite the president's objections.

Discussion prompts

Invite students to answer aloud or in writing.

  • Why do you think the Constitution gives the president the power to veto bills?
  • What might be some reasons Congress would want to override a presidential veto?
  • How does the veto and override process help maintain balance between the branches of government?

Quick activity

Suggested format: pairs or small groups.

Think of a rule or law you would like to change in your community or school. Imagine you are the president and you do not agree with the change. What reasons would you give for vetoing it? Then, imagine you are part of a group trying to override the veto. What arguments would you use to convince others to support the override?
