In theUnited States, thepresident can use theveto power to prevent abill passed by theCongress from becoming law. Congress can override the veto by a two-thirds vote of both chambers.

All state and territorial governors have a similar veto power, as do some mayors and county executives. In many states and territories the governor has additional veto powers, including line-item, amendatory and reduction vetoes. Veto powers also exist in some, but not all,tribal governments.

Abill that is passed by both houses of Congress is presented to the president. Presidents approve of legislation by signing it into law. If the president does not approve of the bill and chooses not to sign, they may return it unsigned, within ten days, excluding Sundays, to the house of theUnited States Congress in which it originated, while Congress is in session.^[1][2] The president is constitutionally required to state any objections to the bill in writing, and Congress is required to consider them, and to reconsider the legislation. Returning the unsigned bill to Congress constitutes a veto.

If Congress overrides the veto by atwo-thirds vote in each house, it becomes law without the president's signature. Otherwise, the bill fails to become law.^[3] Historically, the Congress has overridden about 7% of presidential vetoes.^[4] The votes are made at the qualified majority of the membersvoting, not of the whole number of the houses' members.^[5][6]

A bill becomes law without the president's signature if it is not signed within the ten days allotted, if Congress is still in session. But if Congress adjourns before the ten days have passed during which the president might have signed the bill, then the bill fails to become law.^[2] This procedure is called apocket veto.

Both the president of the United States and US state governors usually issue a veto statement or veto message that provides their reasons for vetoing a measure when returning it to Congress or the state legislature, as required by the US Constitution, state constitutions, or by custom.^[7][8][9] Those statements do not have precedential value, although their reasoning may be respected within the executive branch, and can contribute to the American constitutional tradition.^[9] However, unlike apresidential signing statement, a veto statement does not carry much direct weight in the American legal system, because of its function: if Congress fails to override the veto, the bill and veto become legally irrelevant, but if the override succeeds, the veto message is not considered during subsequent executive implementation or judicial interpretation of the law.^[8]

The president or the state governor may sign the veto statement at asigning ceremony, often with media present, particularly for measures that they wish to disapprove of in a very public fashion.^[10][11]

In theThirteen Colonies, the British colonial government exercised two forms of veto: an absolute veto exercised by the governor of each colony (except for Connecticut, Maryland, and Rhode Island), and another absolute veto exercised by the British king, typically acting through theBoard of Trade.^[12] Both vetoes were absolute and derived from the monarch's power to denyroyal assent. While the British monarch last used this power within the United Kingdom in 1708, in the colonies the practice continued for much longer. From 1696 to 1765, the king struck down nearly 400 laws that had been adopted by an American colonial legislature and approved by the colony's governor.^[12] This heavy use of the veto power was included in the bill of particulars in theDeclaration of Independence in 1776, which states that the king "has refused his Assent to Laws, the most wholesome and necessary for the common good."^[12]

In the years immediately following independence, in theConfederation period, most state constitutions did not provide for a gubernatorial veto at all.^[13] Nationally, thePresident of the Continental Congress likewise lacked a veto power^[14] (although as a legislative presiding officer, the position was not completely analogous to a chief executive). There were three exceptions. South Carolina initially provided for anabsolute veto, but after governorJohn Rutledge vetoed the newstate constitution, he was forced to resign, and his successor signed a constitution that did not provide for any veto power.^[14] InMassachusetts, the constitution of 1780 provided for aqualified veto, in which a gubernatorial veto could be overridden by a two-thirds vote of each chamber of the legislature.^[14] And the 1777New York constitution established a "Council of Revision" made up of the governor, chancellor and state Supreme Court judges, which could issue a qualified veto of legislation.^[14] The Massachusetts and New York constitutions were the only state-level vetoes at the time of theconstitutional convention in 1787, and served as models for the framing of the veto power in theUnited States Constitution.^[14]

With the enactment of theUnited States Constitution (which tookeffect on March 4, 1789) veto power was conferred upon the President of the United States.^[15] During the Constitutional Convention, the veto was routinely referred to as a "revisionary power".^[16] The veto was constructed not as an absolute veto, but rather with limits, such as that Congress can override a veto, and that the president's objections must be stated in writing.^[17] Further, asElbridge Gerry explained in the final days of the convention: "The primary object of the revisionary check of the President is not to protect the general interest, but to defend his own department."^[18]

During the Constitutional Convention, the framers overwhelmingly rejected three proposals for an absolute veto.^[19][20] They also rejected proposals for a combined judicial-executive veto along the lines of the New York constitution.^[21]

The presidential veto power provided by the 1789 Constitution was first exercised on April 5, 1792, when PresidentGeorge Washington vetoed a bill outlining a new apportionment formula.^[22] Apportionment described how Congress divides seats in the House of Representatives among the states based on the US census figures. Washington's stated reasons for vetoing the bill were that it did not apportion representatives according to states' relative populations and that it gave eight states more than one representative per 30,000 residents, in violation of the Constitution.^[23]

The veto power continued to be very rarely used until the presidency ofAndrew Jackson, who vetoed 12 bills.^[24] Although controversial, none of these vetoes were overridden. Congressfirst overrode a presidential veto on March 3, 1845, during the presidency ofJohn Tyler.^[25]

In 1983, the Supreme Court struck down the one-houselegislative veto, onseparation of powers grounds and on grounds that the action by one house of Congress violated the Constitutional requirement of bicameralism. The case wasINS v. Chadha, concerning a foreign exchange student inOhio who had been born in Kenya but whose parents were from India. Because he was not born in India, he was not an Indian citizen. Because his parents were not Kenyan citizens, he was not Kenyan. Thus, hehad nowhere to go when his student visa expired because neither country would take him, so he overstayed his visa and was ordered to show cause why he should not be deported from the United States.^[26]

The Immigration and Nationality Act was one of many acts of Congress passed since the 1930s, which contained a provision allowing either house of that legislature to nullify decisions of agencies in the executive branch simply by passing a resolution. In this case, Chadha's deportation was suspended and theHouse of Representatives passed a resolution overturning the suspension, so that the deportation proceedings would continue. This, the court held, amounted to the House of Representatives passing legislation without the concurrence of the Senate, and without presenting the legislation to the president for consideration and approval (or veto). Thus, the constitutional principle of bicameralism and the separation of powers doctrine were disregarded in this case, and this legislative veto of executive decisions was struck down.

In 1996, theUnited States Congress passed, and PresidentBill Clinton signed, theLine Item Veto Act of 1996. Thisact allowed the president to veto individual items of budgeted expenditures from appropriations bills instead of vetoing the entire bill and sending it back to Congress. However, thisline-item veto was immediately challenged by members of Congress who disagreed with it. In 1998, theSupreme Court ruled 6–3 to declare the line-item veto unconstitutional. InClinton v. City of New York (524 U.S.417 (1998)), the court found the language of the Constitution required each bill presented to the president to be either approved or rejected as a whole. An action by which the president might pick and choose which parts of the bill to approve or not approve amounted to the president acting as a legislator instead of an executive andhead of state—and particularly as a single legislator acting in place of the entire Congress—thereby violating theseparation of powers doctrine.^[27] Prior to this ruling, President Clinton had applied the line-item veto to the federal budget 82 times.^[28][29]

In 2006, SenatorBill Frist introduced theLegislative Line Item Veto Act of 2006 in theUnited States Senate. Rather than provide for an actual legislative veto, however, the procedure created by the act provides that, if the president should recommend the rescission of a budgetary line item from a budget bill he previously signed into law—a power he already possesses pursuant to U.S. Const. Article II—the Congress must vote on his request within ten days. Because the legislation that is the subject of the president's request (or "special message", in the language of the bill) was already enacted and signed into law, the vote by the Congress would be ordinary legislative action, not any kind of veto—whether line-item, legislative or any other sort. The House passed this measure, but the Senate never considered it, so the bill expired and never became law.^[30]

In 2009, SenatorsRuss Feingold andJohn McCain introduced legislation of a limited version of the line-item veto. This bill would give the president the power to withdrawearmarks in new bills by sending the bill back to Congress minus the line-item vetoed earmark. Congress would then vote on the line-item vetoed bill with amajority vote under fast track rules to make any deadlines the bill had.^[31][32][33]

All US states also have a provision by which the governor can vetobills passed by the legislature.^[34] In addition to the ability to veto an entire bill as a "package", many states give the governor additional power to strike or revise parts of a bill without striking the whole bill.

Amendatory veto

Allows a governor to amend bills that have been passed by the legislature. Revisions are subject to confirmation or rejection by the legislature.^[35]

Line item veto

Allows a governor to remove specific sections of an appropriation bill that the legislature has passed. The legislature can override these changes.^[35] 44 governors have this power.^[34] The first state to adopt aline-item veto wasGeorgia, in 1861.^[36]

Pocket veto

Any bill presented to a governor after a session has ended must be signed to become law. A governor can refuse to sign such a bill and it will expire. Such vetoes cannot be overridden.^[35] The governors of 11 states and Puerto Rico have some form of pocket veto.^[37]

Reduction veto

Allows a governor to reduce the amounts budgeted for spending items. Reductions can be overridden by the legislature.^[35]

Package veto

Allows a governor to veto an entire bill. Package vetoes can be overridden by the legislature.^[35] All 50 state governors have this power.^[34] The last state to provide this power wasNorth Carolina in 1996.^[34]

All governors of the five permanently inhabitedUS territories (Guam, theCommonwealth of the Northern Mariana Islands (CNMI),Puerto Rico,American Samoa, and theUnited States Virgin Islands (USVI)) have at least a package veto and a line-item veto. The first territorial governor to be granted line-item veto power was the governor of theTerritory of Hawaii in 1902.^[45] In addition to these gubernatorial veto powers, Congress has expressly reserved theplenary power to nullify territorial legislation in some territories, including Guam,^[46] although not in Puerto Rico.^[47] Some territories'organic laws formerly provided for an absolute presidential veto over territorial legislation as well, as was the case for example in Puerto Rico under theJones-Shafroth Act of 1917,^[48] and in the United States Virgin Islands (USVI) until 1968.^[49]

In Guam^[50] and the USVI,^[51] the territory's organic law defines the governor's veto powers. In Puerto Rico,^[52] the Commonwealth of the Northern Mariana Islands (CNMI),^[53] and American Samoa,^[54] which are governed by a constitution rather than federal statute, veto powers are defined in the constitution.

Thegovernor of Guam has a package veto power and a line-item veto power, both of which can be overridden by a two-thirds vote of the legislature.^[46] The governor also has a pocket veto that cannot be overridden.^[50]

Thegovernor of the CNMI has a package veto and a line-item veto over appropriation bills.^[53] The line-item veto is limited to the appropriations themselves, and does not allow the governor to strike out substantive provisions.^[53] The governor has used this power to provoke legislative change, for example in 2018 with the item veto of theTaulamwaar Sensible CNMI Cannabis Act, which included a veto of a $5 registration fee for cannabis licenses because it was too low,^[55] which led to subsequent legislation imposing a $25 fee.^[56]

Thegovernor of Puerto Rico has a reduction veto in addition to the package and line-item vetoes.^[57] Thelegislature can override any of these vetoes by a two-thirds majority of each chamber.^[52][34] The governor has had the line-item veto since 1917.^[45] The governor also has a pocket veto, which cannot be overridden.^[52]

Thegovernor of American Samoa has package and line-item veto powers, which thelegislature can override within 14 months of the veto date.^[54] If the legislature has overridden the governor's veto, the governor can choose to forward the bill to theSecretary of the Interior for review, at which point it will only become law if the secretary approves it within 90 days.^[54] Some Samoan legislators have criticized the secretarial veto provision as a throwback to colonial government,^[58] but referendums to remove it have been repeatedly defeated, most recently in 2018.^[59] Separately from these executive veto powers, the legislature has retained alegislative veto over certain long-term leases, which theHigh Court of American Samoa upheld as constitutional in 1987.^[60]

The vetoes of thegovernor of the US Virgin Islands has a package veto power and a line-item veto power. Both can be overridden by a two-thirds vote of thelegislature.^[51] The governor also has a pocket veto, which cannot be overridden.^[51] The elected governor has held the line-item veto since 1954, under theRevised Organic Act of the Virgin Islands.^[45] In 1976, theThird Circuit Court of Appeals ruled that the existing statutory language did not allow for an override.^[49] However, the organic law was amended in 1977 to allow the line-item veto to be overridden.^[61][62]

Mayors in amayor-council government often have a veto power overlocal ordinances passed by thecity council. The mayoral veto is a typical feature of "strong mayor" systems in which the mayor is the chief executive and the council is limited to legislative matters.^[63] These systems are more common in large cities.^[64] The mayors of New York, Los Angeles and Chicago all have veto power,^[65] as does the mayor ofWashington, D.C.^[66] The mayor ofHouston, however, does not.^[65][67] The proportion of council votes required to override a veto is most commonly 2/3 as in the federal system, although inSan Diego a 5/8 vote is required.^[68]

Nationwide, less than a third of US mayors have a veto power.^[69] In particular, veto powers are less common incouncil-manager governments. However, the mayor ofCharlotte, who otherwise serves chiefly as a ceremonial head of government and tiebreaker on council votes, has a veto power over most city legislation.^[70][71] Legislation requires six votes to pass, and seven votes to override a veto.^[70] For example, in 2008 the council overrode the mayor's veto of a development project.^[72]

In the early United States, mayoral veto powers were rare, although they were granted for example to the mayor ofBaltimore under the charter of 1796 and the mayor of Washington under the charter of 1802.^[73] Mayors in the early 19th century were often appointed rather than elected, and typically served one-year terms.^[74] As cities grew, the mayoral role was strengthened, becoming an independently elected office with multi-year terms, in part as an effort to limit the political power of immigrants.^[75] With this change toward a stronger mayoral role, mayoral veto powers became more common, particularly after 1850.^[74] In most cases there was a two-thirds requirement for override; however, in some cases (such asLouisville and inNew York City before 1853) the mayor had only a suspensive veto that the council could override by a simple majority vote.^[76]

In addition to mayoral vetoes in cities and towns, some states also grant a veto power to the elected executive of some or all counties. Arkansas adopted a constitutional amendment in 1974 that gave allcounty judges a veto that can be overridden by a three-fifths majority of thequorum court.^[77] In Texas, in contrast, the county judge has no veto power, and instead votes as a member of theCommissioners' Court.^[78] In New York, counties adopting a charter may choose to have a county executive either with or without veto power.^[79] Wisconsin granted a veto to county executives by constitutional amendment in 1962, although as of 2020^[update], this applies only to twelve counties that have adopted a county executive form of government.^[80] Likewise in California, elected county executives have a veto, but only the consolidated city-county ofSan Francisco has an elected executive.^[81] And in some states, such as Iowa since 1981, counties can adopt an elected-executive system with a veto power, but none have done so.^[82]

The constitutions of manyNative American tribes contain an executive veto power over bills passed by thetribal council.^[83] For example, the chairperson of theLittle Traverse Bay Bands of Odawa Indians has a veto power, including over budgetary matters.^[84] Some constitutions give the executive the power to refer a law to a referendum rather than to veto it directly.^[85]

In theNavajo Nation government, thepresident has a package veto power as well as a line-item veto for budgetary matters. The line-item veto cannot be overridden, under the terms of a 2009 referendum.^[86] The package veto was notably used by PresidentKelsey Begaye in 2001 to force a compromise on a law that allowedgaming on Navajo Nation land, after the council failed to override the veto.^[87]

In addition, some tribal constitutions adopted under theIndian Reorganization Act of 1934 give theSecretary of the Interior a veto power over tribal legislation.^[88] TheNisqually Indian Tribe of the Nisqually Reservation constitution grants a secretarial veto over all ordinances issued under itspolice power.^[89] This has sometimes caused difficulties for tribal governments. From 1975 to 2021, the "Morton memorandum" directed allBIA superintendents and area directors to disapprove any tribal legislation regulating water use on Indian reservations that required secretarial approval under tribal law.^[90] Thus, tribes without such provisions in their constitutions could regulate water use, but those whose constitutions granted a secretarial veto faced an additional obstacle to doing so.^[90] Some tribes have amended their constitutions to eliminate the secretarial veto, as theCitizen Potawatomi Nation did in 2007.^[91]
