The United States Congress is made up of the House of Representatives and the Senate, and is one of the three coequal branches of government. The Constitution grants Congress the sole authority to enact legislation and declare war, the right to confirm or reject many Presidential appointments, and substantial investigative powers. The Legislative Vesting Clause of the Constitution provides that all legislative Powers herein granted shall be vested in a Congress of the United States. This clause limits Congress's powers to those specifically enumerated in the Constitution. These enumerated powers are listed in Article I, Section 8, and include the power to lay and collect taxes, pay debts and borrow money, regulate commerce, coin money, establish post offices, protect patents and copyrights, establish lower courts, declare war, and raise and support an Army and Navy. The Constitution also includes several checks and balances to prevent Congress from growing too powerful, including the President's qualified veto power over legislation.

Enumerated powers
The Constitution of the United States grants Congress significant powers, making it one of the three coequal branches of government. Article I of the Constitution enumerates the powers of Congress and the specific areas in which it may legislate.
The Enumerated Powers of Congress are listed in Article I, Section 8 of the Constitution. These include:
- The power to lay and collect taxes, duties, imposts, and excises, to pay the debts and provide for the common defence and general welfare of the United States.
- The power to borrow money on the credit of the United States.
- The power to regulate commerce with foreign nations, among the several states, and with the Indian Tribes.
- The power to establish a uniform rule of naturalization and uniform laws on the subject of bankruptcies throughout the United States.
- The power to coin money, provide for the punishment of counterfeiting, and secure intellectual property rights for authors and inventors.
- The power to establish post offices and protect patents and copyrights.
- The power to establish lower courts.
- The power to declare war, grant letters of marque and reprisal, and make rules concerning captures on land and water.
- The power to raise and support an Army and Navy, with appropriations of money for a maximum term of two years.
- The power to make all laws "necessary and proper" to carry out the enumerated powers, also known as the Elastic Clause.
The Elastic Clause has allowed Congress to expand its powers to fit its needs. For example, in McCulloch v. Maryland (1819), the Supreme Court ruled that Congress had the power to establish a national bank under the Necessary and Proper Clause to execute its powers to collect taxes, pay debts, and borrow money.

Separation of powers
The United States Constitution establishes a system of separation of powers, dividing the government into three distinct branches: the Legislative, Executive, and Judicial. This principle, influenced by the writings of Charles de Secondat, Baron de Montesquieu, aims to prevent the accumulation of power in a single branch and safeguard against potential abuses.
Legislative Branch
The Legislative Branch, comprising the House of Representatives and the Senate, holds the sole authority to enact legislation and declare war. Congress, as the central law-making body, is responsible for creating and debating laws that govern the nation. It can also override presidential vetoes with a two-thirds majority in both the Senate and the House of Representatives. Additionally, Congress has investigative powers, enabling it to oversee the federal government, investigate misuse of funds, and gather information for crafting new legislation.
Executive Branch
The Executive Branch, headed by the President, is responsible for enforcing the laws created by Congress. The President has the power to veto congressional bills, make treaties, and appoint officials with the advice and consent of the Senate. While the President can take actions to ensure the execution of laws, they must still act within the boundaries set by Congress and the Constitution.
Judicial Branch
The Judicial Branch, established by Article III of the Constitution, includes the Supreme Court and inferior courts established by Congress. This branch wields the power to interpret and apply the laws created by Congress, ruling on their constitutionality. The judiciary acts as a check on both the Legislative and Executive branches, voiding any laws or actions that violate the Constitution. The Legislative Branch, in turn, has the power to confirm the President's judicial appointments and impeach federal judges, including Supreme Court justices.
The separation of powers is not rigid, as the Constitution incorporates a system of checks and balances. This design allows for interdependence and collaboration among the branches while also providing mechanisms for each branch to limit the powers of the others. This system helps maintain a delicate balance, preventing any single branch from dominating the others and ensuring a free and democratic form of government.

Checks and balances
The US Constitution divides the federal government into three branches: the legislative, executive, and judicial. This separation of powers ensures that no individual or group will have too much power and creates a system of checks and balances.
The legislative branch makes laws, but the President in the executive branch can veto those laws with a Presidential Veto. The legislative branch can also impeach and remove the President from office if the President has committed crimes of treason, high crimes, or misdemeanors. The legislative branch also has the power to approve Presidential nominations, control the budget, and impeach and remove members of the executive and judicial branches.
The executive branch enforces the law and can declare Executive Orders, which are like proclamations that carry the force of law. However, the judicial branch can declare those acts unconstitutional. The executive branch, through Federal agencies, has the responsibility for the day-to-day enforcement and administration of Federal laws.
The judicial branch interprets the laws, but the President nominates Supreme Court justices, court of appeals judges, and district court judges who interpret the laws. The judicial branch can also declare laws passed by Congress to be unconstitutional in whole or in part.
The system of checks and balances encourages constant tension and conflict between the branches, which can be beneficial. It ensures that the government functions through the interplay of power among the three branches, with each branch having its own authority but also depending on the authority of the other branches.

Judicial review
The Constitution limits the powers of Congress by enumerating the powers it does have. This is a reflection of the Framers' experience as colonists living under the rule of the powerful British Parliament of the 1700s.
Article I, Section 8 of the Constitution contains a list of powers granted to Congress, including the power to lay and collect taxes, pay debts and borrow money, regulate commerce, coin money, establish post offices, protect patents and copyrights, establish lower courts, declare war, and raise and support an Army and Navy.
However, the list ends with the "Elastic Clause", which allows Congress to make all laws "necessary and proper" to carry out the enumerated powers. This has allowed Congress to stretch its powers to fit its needs. For example, in McCulloch v. Maryland (1819), the Supreme Court ruled that under the Necessary and Proper Clause, Congress had the power to establish a national bank to carry out its powers to collect taxes, pay debts, and borrow money.
The Vesting Clause of Article I grants all federal legislative power to Congress, establishing that Congress consists of the House of Representatives and the Senate. In combination with the vesting clauses of Article II and Article III, the Vesting Clause of Article I establishes the separation of powers among the three branches of the federal government. This separation of powers, by which each branch may exercise only its own constitutional powers and no others, is fundamental to the idea of a limited government accountable to the people.
The nondelegation doctrine, an implied extension of the separation of powers principle, prohibits Congress from delegating its legislative authority to either of the other branches of government. However, the Supreme Court has ruled that Congress does have the latitude to delegate regulatory powers to executive agencies as long as it provides an "intelligible principle" which governs the agency's exercise of the delegated regulatory authority.
The Supreme Court has also affirmed Congress's power to investigate as an implication of its power to legislate. This power is as broad as Congress's powers to legislate, but it is limited to inquiries that are "in aid of the legislative function"; Congress may not "expose for the sake of exposure".
The courts can enforce the Constitution's limitations on Congress's powers by declaring a legislative act in excess of such powers to be void. Alexander Hamilton, who supported ratification of the Constitution, argued that this was the only way to preserve limitations on legislative power in practice. Less than two decades after the ratification of the Constitution, the Supreme Court asserted its authority to review the constitutionality of legislative acts and to declare void those provisions of legislation that violated the Constitution.

Federalism
Firstly, the Constitution restricts Congress's authority by outlining a set of carefully defined powers, while most other legislative powers are reserved for the states or the people. These enumerated powers include the ability to lay and collect taxes, pay debts and borrow money, regulate commerce, coin money, establish post offices, protect patents and copyrights, establish lower courts, declare war, and raise and support an Army and Navy. The Constitution also grants Congress the power to make all laws that are "necessary and proper" to carry out these powers, also known as the Elastic Clause. This clause has allowed Congress to expand its powers, as seen in McCulloch v. Maryland (1819), where the Supreme Court ruled that Congress could establish a national bank under the Necessary and Proper Clause.
Secondly, the Constitution's federalism-based restrictions prevent the national government from enacting laws that exceed federal power or infringe upon state sovereignty. This is affirmed by the Tenth and Eleventh Amendments, which prohibit the national government from "commandeering" state authority for its purposes. For example, Congress may not force a state's legislature or executive to implement federal commands. Additionally, the principle of state sovereign immunity limits Congress's ability to bring legal action against states or state officials.
