The system of checks and balances is an important part of the Constitution. With checks and balances, each of the three branches of government can limit the powers of the others. This way, no one branch becomes too powerful
Congress
The most important power of Congress is its legislative authority; with its ability to pass laws in areas of national policy.
As the branch most responsive to the will of the people (who elect its members), Congress has the power to pass laws, declare war, ratify treaties, and levy taxes. The executive branch conducts foreign affairs and commands the armed forces.
