What Does US President Do

One person sits at the centre of the American government, and almost every American news story passes through that person’s office sooner or later. The president signs laws, commands the military, meets foreign leaders, appoints judges, and speaks for the country in moments of crisis. The job is so large that no single description can capture all of it. But its main parts can be explained in simple words, starting with the Constitution that creates it.

This post sets out what the president does, what powers are shared with others, and what limits the job. It describes the office in general, not any one president.

Who Can Become President

The Constitution sets three conditions for the presidency. A president must be a natural-born citizen of the United States, which includes a person born abroad to parents who are American citizens. The president must be at least 35 years of age. And the president must have been a resident of the United States for at least 14 years.

Those are the only formal conditions listed by Vote Smart in its guide to the presidency. In practice, of course, winning the presidency also requires winning an election through the Electoral College, building a national campaign, and gaining the support of a major political party. But the written rules are short. Age, citizenship and residence are the gate. Everything after that is politics.

Head Of State And Head Of Government

In many countries, two different people hold the top jobs: a head of state who represents the country, and a head of government who runs it day to day. In the United States, the president is both. The president represents America at home and abroad, welcomes foreign ambassadors, and speaks for the nation at ceremonies and in crises. The president also runs the executive branch of the federal government, the vast machinery of departments, agencies and offices that carry out the laws.

That double role is why the presidency feels so personal. When Americans praise or blame the government, they usually praise or blame the president by name. The president is the face of the country and the manager of its government at the same time, and the two jobs cannot be separated.

Commander In Chief Of The Armed Forces

According to Article II of the Constitution, the president serves as commander in chief of the armed forces, and commissions officers of the armed forces. In plain words, the president is the top civilian authority over the military. Generals and admirals answer to the president, not the other way around.

This power is large, but it is not unlimited. Only Congress can declare war, and Congress controls military funding. The president can order troops into action and direct military operations, and in practice presidents have done so many times without a formal declaration of war. But the need for Congress to pay for the military, and to pass laws about it, keeps the commander in chief inside a system of shared control.

Making Sure The Laws Are Carried Out

The Constitution says the president must take care that the laws be faithfully executed. That phrase describes the president’s central daily job: making sure the laws passed by Congress are actually put into practice. The president does this through the executive departments, such as the departments of State, Treasury, Defence, Justice and others, each led by a secretary who answers to the president.

Wielding the executive power, as Vote Smart puts it, means directing this machinery. The president issues orders to agencies, sets priorities for enforcement, and decides how the government’s resources are used. A law on paper means little until the executive branch acts on it, and the president is the person responsible for seeing that it does.

Appointing Judges And Officials

The president appoints Cabinet officials, White House staff and Supreme Court justices. Cabinet officials lead the great departments of government. White House staff run the president’s own office. Supreme Court justices serve on the highest court in the land, and their decisions shape American law for generations.

These appointments are among the most lasting things a president does. A Cabinet secretary may serve for a few years. A Supreme Court justice serves for life, or until retirement. That is why appointments are fought over so fiercely. The president chooses, but for the most important posts, the Senate must agree, which brings us to the powers the president shares.

Powers Shared With The Senate

Some presidential powers cannot be used alone. The president makes treaties with other countries, but treaties need the Senate’s agreement to take effect. The president appoints ambassadors, Cabinet members and Supreme Court justices, but those appointments also need Senate confirmation.

This sharing is deliberate. It stops any president from remaking foreign policy or the courts without the agreement of at least part of Congress. It also means that a president whose party does not control the Senate may find appointments blocked or delayed. The Senate’s role is often described as advice and consent: the president proposes, and the Senate decides whether to agree.

Powers Shared With Congress As A Whole

The president’s role in lawmaking is shared with Congress as a whole. The president approves legislation, signing bills passed by Congress into law. A president may also refuse to sign, using the veto, which sends the bill back to Congress. Congress can override a veto, but only with a large majority in both houses, which is difficult to achieve.

The president may also convene Congress in special sessions, calling lawmakers back when urgent business requires it. And the president receives ambassadors from other countries, a formal act that recognises foreign governments and keeps diplomatic relations running. Each of these powers links the president to the legislature, so that no law is made, and no foreign relationship is set, by one person alone.

Pardons And Mercy

The president may grant reprieves and pardons for federal offences, except in cases of impeachment. A pardon forgives a federal crime and removes its legal consequences. A reprieve delays a punishment. This power is one of the few the president can use alone, without Congress.

Pardons are often used at the end of a presidency, and they are often controversial, because they can free people convicted of serious crimes. Supporters say the power is a necessary act of mercy, a way to correct injustice when courts cannot. Critics say it can look like favouritism. Either way, it is a reminder that the president holds a power no judge and no lawmaker holds in the same form.

The President As The Nation’s Voice

Beyond the written powers, the president has a power that is harder to define: the power of the platform. When the president speaks, the country listens, and so does the world. A speech can calm a crisis, rally support for a policy, or change the terms of a debate overnight. A single sentence can move markets, reassure allies or alarm enemies.

This voice matters most in emergencies. After an attack, a disaster or a financial shock, Americans look to the president for explanation and direction. The president’s words do not change the law by themselves, but they shape what people believe is happening, and what they expect to happen next. In a large, divided country, that shaping power is one of the most important parts of the job.

What The President Cannot Do

The president cannot make laws alone, cannot spend money Congress has not approved, cannot appoint senior officials without Senate agreement, and cannot ignore court rulings. The Constitution divides power on purpose, so that the president, Congress and the courts each check the others. A president who oversteps can be challenged in court, blocked by Congress, or, in the most serious cases, removed through impeachment.

The president also cannot stay in office by personal choice alone. Presidents are chosen every four years through the Electoral College, and must face the voters again to continue. That regular test is the final limit on the job. However powerful a president seems, the office itself belongs to the people who elect the holder, and it returns to them on a fixed schedule.

Frequently Asked Questions

What does the US president do?

The US president serves as both head of state and head of government, runs the executive branch, and carries out the powers listed in Article II of the Constitution. The president commands the armed forces, takes care that the laws are faithfully executed, appoints Cabinet officials and Supreme Court justices, makes treaties, approves legislation, receives ambassadors, convenes Congress in special sessions, and grants pardons for federal offences. The president also speaks for the nation in crises and sets the direction of the federal government through the departments and agencies.

Who can become president of the United States?

A president must be a natural-born citizen of the United States, which includes a person born abroad to American citizen parents, must be at least 35 years of age, and must have been a resident of the United States for at least 14 years, according to Vote Smart’s guide to the presidency. Those are the formal constitutional conditions. In practice, a candidate must also win election through the Electoral College, which chooses the president and vice president every four years.

Is the president the commander in chief of the military?

Yes, under Article II of the Constitution the president serves as commander in chief of the armed forces and commissions officers of the armed forces. That makes the president the top civilian authority over the military, with generals and admirals answering to the president. The power is shared in practice, because only Congress can declare war and Congress controls military funding, so the president directs operations while Congress pays for the military and passes laws about it.

What powers does the president share with Congress?

The president shares treaty-making with the Senate, which must agree for treaties to take effect, and shares appointments of ambassadors, Cabinet members and Supreme Court justices with the Senate, which must confirm them. With Congress as a whole, the president shares lawmaking by approving legislation, signing bills into law or refusing them through the veto, which Congress can override only with a large majority in both houses. The president also convenes Congress in special sessions and receives foreign ambassadors, linking the presidency to the legislature at every step.

Can the president pardon anyone?

The president may grant reprieves and pardons for federal offences, except in cases of impeachment, according to Article II of the Constitution. A pardon forgives a federal crime and removes its legal consequences, while a reprieve delays a punishment. The power applies only to federal offences, not to state crimes, and it is one of the few powers the president can use without Congress, which is why pardons, especially at the end of a presidency, are often praised as mercy and criticised as favouritism.
