Founding era The phrase "unitary executive" was discussed as early as the
Philadelphia Convention in 1787, and referred only to having a single individual fill the office of president, as proposed in the
Virginia Plan. The alternative was to have several executives or an executive council, as proposed in the
New Jersey Plan and as promoted by
Elbridge Gerry,
Edmund Randolph, and
George Mason.
James Madison was a leading advocate of the unitary executive and successfully argued in favor of the president's power to remove administrative appointees under the Constitution in the
Decision of 1789. Madison said in 1789, "if any power whatsoever is in its nature Executive, it is the power of appointing, overseeing, and controlling those who execute the laws." He had reservations about removal power extending to the
comptroller of the Treasury Department, as he believed that office would share both judicial and executive responsibilities. Other legislators, such as
Theodore Sedgwick,
Michael Jenifer Stone, and
Egbert Benson argued that the role would primarily be executive and should fall under the president's power. Madison ultimately withdrew his proposal to exempt the comptroller from the president's removal power. In 1788, the pseudonymous letters of the
Federal Farmer defended the proposed unitary executive, arguing that "a single man seems to be peculiarly well circumstanced to superintend the execution of laws with discernment and decision, with promptitude and uniformity." In
Federalist No. 77,
Alexander Hamilton wrote with regard to the
Senate and presidential appointments that "The consent of that body would be necessary to displace as well as to appoint". Hamilton's usage of "displace" has traditionally been thought to mean "removal", and thus a limit on presidential power. Other legal scholars have interpreted "displace" to mean replacement of an appointee with another, not removal itself. Historically, as part of the campaign to support ratification,
Alexander Hamilton contrasted the powers of the presidency and those of the
King of Great Britain. Namely, the King exercised powers in military affairs that would be delegated to Congress.
Judicial decisions In the 1926 case of
Myers v. United States, the United States Supreme Court ruled that the president has the exclusive power to remove executive branch officials, and does not need the approval of the Senate or any other legislative body. The court also wrote: The ordinary duties of officers prescribed by statute come under the general administrative control of the President by virtue of the general grant to him of the executive power, and he may properly supervise and guide their construction of the statutes under which they act in order to secure that unitary and uniform execution of the laws which article 2 of the Constitution evidently contemplated in vesting general executive power in the President alone. Subsequent cases such as ''Humphrey's Executor v. United States
(presidential removal of certain kinds of officers), and Bowsher v. Synar'' (control of executive functions) have flexed the doctrine's reach back and forth.
Justice Scalia in his solitary dissent in
Morrison v. Olson argued for an unlimited presidential removal power of all persons exercising executive branch powers, which he argued included the
independent counsel; the court disagreed, but later moved closer to Scalia's position in
Edmond v. United States. Many of the proponents clerked for Justice Scalia. The four justices appointed by a Democratic president dissented in
Seila, arguing that the constitution makes no such claims.
Collins was a very similar case taken up the next year, and the precedent of
Seila was applied to
Collins in a 7−2 ruling. These two rulings lend support to Trump's firing of
Hampton Dellinger as head of the
U.S. Office of Special Counsel in 2025. In March 2025, the D.C. Circuit Court of Appeals ruled that the president could legally remove members of the
National Labor Relations Board as well as the
Merit Systems Protection Board because both wield executive power. The court found that restrictions on the president's power to remove officers of the executive branch are unconstitutional. The ruling was seen as a likely precursor to the Supreme Court reviewing its ''Humphrey's Executor'' precedent.
Growth of presidential powers , who served as
Attorney General on two separate occasions, has advocated for the unitary executive theory. The power of the presidency has grown since the 1970s due to key events and to Congress or the Courts not being willing or able to rein in presidential power. With strong incentives to grow their own power, presidents of both parties became natural advocates for the theory, Republican presidents did not follow through on promises to use unitary executive power to shrink government, instead using their administrations to advance their policies. with significant growth post-9/11 as conservatives have most readily embraced the idea of a unitary executive.
Dick Cheney and the George W. Bush administration supported the theory. For example, Bush wrote in a statement while signing the
Detainee Treatment Act that he would "construe Title X in Division A of the Act in a manner consistent with the constitutional authority of the President to supervise the unitary executive branch and as Commander in Chief and consistent with the constitutional limitations on the judicial power." Critics acknowledge that part of the president's duty is to "interpret what is, and is not constitutional, at least when overseeing the actions of executive agencies"; at the same time, they accused Bush of overstepping that duty by his perceived willingness to overrule U.S. courts. During his confirmation hearing to become an associate justice on the
United States Supreme Court,
Samuel Alito seemed to endorse a weaker version of the unitary executive theory.
Barack Obama campaigned against the theory but embraced some aspects of it after the
2010 midterm elections. Donald Trump exerted the greatest control over the executive during
his presidency than any other modern president, often citing Article II of the Constitution. In 2019, he said, "I have an Article II, where I have the right to do whatever I want as president."
Bill Barr notably supported unitary executive theory before his confirmation as attorney general in a 2018 memo criticizing the
Russia probe.
Project 2025 proposed using the theory to justify giving Trump or another president maximum control over the executive branch. The
Trump 2024 campaign platform included an expansion of executive power grounded in this theory. Upon taking office, Trump undertook
mass firings of federal employees,
inspectors general, and members of independent agencies and oversight boards who could attempt to block or constrain his moves. Legal analysts described such firings as setting up
Supreme Court cases that could expand his power over independent executive branch agencies that Congress arranged to be insulated from presidential control. Since taking office, Trump has expanded his control over executive branch agencies and the
civil service, ordering many of them to
target his political opponents and organizations aligned with the Democratic Party. His administration has asserted that, under unitary executive theory, it has a constitutional right to control and even cease enforcement of federal law. Legal experts described it as claiming a "constitutional power to immunize private parties to commit otherwise illegal acts with impunity". Trump and his subordinates have been described as embracing some of the theory's most extreme versions. ==Criticism==
