Donald Trump has signed executive orders faster than any modern president. Here’s what an executive order actually is, and the limits on what it can do.
An executive order is an official instruction from the president to the federal government, such as government departments and agencies. It’s signed by the president and published in the Federal Register, the U.S. government’s official record.
The president’s power to issue them comes from the Constitution, which makes the president head of the executive branch, and from laws passed by Congress that give the president specific powers.
Executive orders can set policy, reorganise government agencies, change how existing laws are enforced and direct officials to take action. They are often used when a president can’t get, or doesn’t want to wait for, legislation through Congress.
A record pace
Every president since George Washington has used them, but some far more than others. Franklin D. Roosevelt signed more than 3,700, many during the Great Depression and the Second World War.
Trump signed 46 executive orders in his first month back in office in January 2025, and 288 in his second term to the end of September 2026, according to Ballotpedia. That’s an average of about 173 a year, the highest of any president since at least 1981. By comparison, Joe Biden averaged about 41 a year.
His orders have covered tariffs, immigration, federal government jobs, energy and diversity programs, among many other areas.
The limits
An executive order isn’t a law. It can’t create new spending without Congress, override an existing law or breach the Constitution.
Courts can block or strike down orders that go beyond a president’s legal powers. Many of Trump’s orders have been challenged in court. In February 2026, the Supreme Court ruled that he couldn’t use an emergency economic powers law to impose broad tariffs, striking down a central part of his trade policy.
Congress can also pass laws that overturn or cut funding for an order, although the president can veto those laws, and overriding a veto needs a two-thirds vote in both chambers.
The biggest limit is time. Because an order isn’t a law, the next president can cancel it on their first day. Trump reversed dozens of Biden’s orders on his first day back in office, just as Biden had reversed many of Trump’s in 2021.
That’s why the most lasting changes in American policy usually come through laws passed by Congress, rather than executive orders.
