The U.S. Constitution divides national power so no single branch can control the government alone. The President leads the executive branch, while Congress makes laws and controls many major national decisions. Their powers overlap most clearly in war, the budget, appointments, and treaties.
Understanding this balance helps explain why government action often requires negotiation, delay, and compromise.
The President can act quickly in areas such as military leadership, diplomacy, and administration, but Congress can approve, limit, or block many of those actions. Congress controls funding, declares war, confirms many appointments, and approves treaties through the Senate. The President can veto bills, nominate officials, command the armed forces, and negotiate with other nations.
The system works through checks and shared powers, not through total independence.

Common Mistakes to Avoid
- Saying the President can declare war is wrong because the Constitution gives the power to declare war to Congress, even though the President commands the military.
- Assuming Congress must accept the President’s budget is wrong because the President proposes a budget, but Congress writes and approves spending laws.
- Thinking every presidential appointment is automatic is wrong because many high-level nominees need Senate confirmation before taking office.
- Believing a treaty becomes law as soon as the President signs it is wrong because the Senate must approve treaties by a two-thirds vote.
Practice Questions
- 1 The Senate has 100 members. How many votes are needed to approve a treaty if approval requires a two-thirds vote?
- 2 A bill is vetoed by the President. The House has 435 members and needs a two-thirds vote to override. If all members vote, how many House votes are needed to override the veto?
- 3 A President sends troops into a conflict and asks Congress for funding. Explain how both branches have power in this situation and identify one check each branch has on the other.
