This article provides a list of political scandals that involve officials from the government of the United States, sorted from oldest to most recent.

Scope and organization of political scandals

This article is organized by presidential terms in order, older to recent, and then divided into scandals of the federal Executive, Legislative, and Judicial branches of government. Members of both parties are listed under the term of the president in office at the time the scandal took place, even though they may not be connected with the presiding president.

In this article, the term "politician" (a person who is professionally involved in politics) includes not only those elected, but also party officials, candidates for office, their staffs and appointees. Please note that every president directly selects, appoints or hires several thousand people. Each of them selects thousands more. Private citizens should only be mentioned when they are closely linked to the scandal or politician, such as Jack Abramoff. This list also does not include crimes that occur outside the politician's tenure (such as before or after his term in office) unless they specifically stem from acts made while in office and discovered later.

Scandal is defined as "loss of or damage to reputation caused by actual or apparent violation of morality or propriety". Scandals are separate from 'controversies', (which implies two differing points of view) and 'unpopularity'. Many decisions are controversial, many decisions are unpopular, that alone does not make them scandals. Breaking the law is a scandal. The finding of a court is the sole method used to determine a violation of law, but it is not the sole method of determining a scandal. Also included as scandals are politicians who resign, quit, run, or commit suicide while being investigated or threatened with investigation.

Notoriety is a major determinant of a scandal, that is, the amount of press dedicated to it. Misunderstandings, breaches of ethics, unproven crimes or cover-ups may or may not result in inclusion depending on the standing of the accused, the amount of publicity generated, and the seriousness of the crime, if any. Drunk driving may be a conviction, but is usually too minor and too common to mention unless there are multiple convictions and/or jail time.

Given the political nature of Congress in which the leading party has determining power, politicians who are rebuked, denounced, censured, admonished, condemned, suspended, reprimanded, found in contempt, found to have acted improperly, or used poor judgement are not included unless the scandal is exceptional or leads to expulsion or conviction.

Government under the Articles of Confederation (1777–1789)

Thomas Conway and Horatio Gates created a movement or conspiracy, known as the Conway Cabal, to remove George Washington as Commander of the Continental Army. (1777–1778) Silas Deane was appointed by the Continental Congress to be Ambassador to France. He was accused of mismanagement and treason. As he was attempting to clear himself of the charges, he died suddenly. The charges were eventually reversed or dropped. (1777)

George Washington administrations (1789–1797)

Legislative branch

Senator William Blount (Democratic-Republican-TN) was expelled from the Senate for conspiring of his own accord to have Great Britain to take over Spanish-controlled Louisiana and Florida in order to boost local land prices. (1797)

John Adams administration (1797–1801)

Executive branch

The XYZ Affair was the French seizure of over 300 US ships and demands for bribes and apologies, which led to a Quasi-War causing the US Congress to issue the famous phrase, "Millions for defense, sir, but not one cent for tribute!". Real war was averted by treaty. (1798–1800)

Legislative branch

Matthew Lyon (Democratic-Republican KY) was the first Congressman recommended for censure for spitting on Ralph Griswold (Federalist-CT). The censure failed to pass. Also found guilty of violating John Adams's Alien and Sedition Acts and sentenced to four months in jail, during which he was re-elected. (1798)

Thomas Jefferson administrations (1801–1809)
