Executive Orders Explained: How Presidents Govern Without Congress
Presidents have used executive orders since George Washington.

They are powerful tools for fast action — but they are not laws, they can be reversed by the next president, and courts can strike them down. Here is how they work and what Trump's record-setting pace means for 2026.
- Executive orders are legally binding directives to the executive branch — they do not require Congressional approval but cannot override federal law.
- Trump signed 100+ executive orders in his second term's first 100 days — a record pace, covering immigration, DOGE, DEI, and energy policy.
- Executive orders can be overturned by future presidents, congressional legislation, or federal court rulings — all three have blocked Trump second-term EOs.
- The scope of executive power is a defining constitutional question of the current era — courts have struck down EOs on immigration, DEI, and federal workforce in 2025-2026.
What Executive Orders Are — and Are Not
An executive order is a written directive from the president instructing the executive branch — departments, agencies, and federal employees — how to carry out their duties. EOs are published in the Federal Register and have the force of law within the executive branch. They are numbered sequentially: the first EO signed by a new president continues the numbering from where the previous president left off.
What EOs can do: Direct agencies to enforce or deprioritize enforcement of existing laws; establish White House offices or working groups; set federal procurement policy; reorganize certain executive branch functions; impose sanctions on foreign entities; direct immigration enforcement priorities; set classification and declassification standards.
What EOs cannot do: Create new criminal law (only Congress can do that); appropriate or spend money (the Appropriations Clause gives Congress that power); override existing federal statutes; expand the president's constitutional authority beyond what Article II provides; bind private citizens who are not employed by or contracting with the executive branch.
Presidential memoranda and proclamations: Presidents also issue "presidential memoranda" (functionally similar to EOs but used for specific directives) and "proclamations" (used for official announcements, tariffs, and national emergencies). All are forms of presidential directive. Trump's first-100-days count typically includes all three categories.
Executive Order Use by President (Selected)
| President | Total EOs | Notable EOs |
|---|---|---|
| FDR (1933-1945) | 3,721 | New Deal agencies, Japanese-American internment (EO 9066), WWII mobilization |
| Truman (1945-1953) | 907 | Desegregation of US military (EO 9981, 1948) |
| Obama (2009-2017) | 276 | DACA (presidential memorandum), DAPA (blocked by courts), Paris climate commitments |
| Trump 1st term (2017-2021) | 220 | Travel ban (blocked, revised, upheld), Paris withdrawal, border wall declaration |
| Biden (2021-2025) | 162 | Revoked 6 Trump EOs Day 1; student loan forgiveness attempts; climate EOs |
| Trump 2nd term (2025-) | 100+ (first 100 days) | Birthright citizenship (blocked), DOGE creation, DEI dismantling, tariff proclamations |
Why This Matters for 2026
EOs allow fast policy change — Trump reshaped immigration enforcement, DEI programs, and federal contracting rules in days. But without congressional backing, the changes are fragile: a Democratic president could reverse them on January 20, 2029. This creates pressure on Republicans to convert priority EO policies into durable statutes in the 2025-26 congressional session — the "reconciliation" legislation push is partly this effort.
Democrats have used court injunctions blocking Trump EOs as 2026 messaging: the DOGE cuts that were blocked, the birthright citizenship order that was struck down. For Republican voters, the same injunctions are evidence of judicial overreach. The number of court-blocked EOs is an unusually high share of the total issued — a data point each party uses to tell a different story about executive overreach vs. judicial activism.
Trump's mass revocation of Biden EOs on Day 1 (as Biden revoked Trump EOs on Day 1 in 2021) has highlighted a fundamental weakness of governing by executive order: it is one-election-reversible policy. Businesses and states that must comply with EO-driven rules face uncertainty. This whiplash creates pressure across the political spectrum to codify major policies into law — a dynamic that shapes congressional legislative priorities ahead of 2026.
Frequently Asked Questions
Can Congress override an executive order?
Congress can pass legislation that directly contradicts or supersedes an executive order, making it effectively void. If the statute is clear, the EO cannot stand. Congress can also pass a "joint resolution of disapproval" for some presidential actions (under the Congressional Review Act for agency rules). The practical barrier is that the president can veto such legislation, requiring a two-thirds override majority — which is rarely achievable. In practice, court challenges and future presidential revocations are more common routes to EO invalidation than congressional override.
What is a "national emergency" executive order?
Under the National Emergencies Act (1976), the president can declare a national emergency, unlocking dozens of special statutory powers Congress has granted for emergency use — including military construction funding, certain trade restrictions, and expanded law enforcement authorities. National emergency declarations do not expire automatically; they must be renewed annually. As of 2026, there were more than 40 active national emergencies, some decades old. Trump's use of emergency declarations for tariffs under IEEPA has been one of the major 2025-26 court battlegrounds.
Do executive orders apply to state governments?
No. Executive orders bind the federal executive branch only. States are separate sovereigns under the Constitution's Tenth Amendment and cannot be directly commanded by presidential executive order. However, EOs can affect states indirectly: federal funding conditions can be attached to state compliance with federal priorities, and federal agencies that regulate within states operate under EO directives. The administration's attempts to use federal funding as leverage over states — for immigration enforcement cooperation, for example — have generated their own extensive litigation.
