How to Use This Glossary Terms are listed alphabetically. Each definition explains the term as it is used in the context of this report, which may differ from broader legal or colloquial usage. Where a term has a specific legal definition that differs from common understanding, the legal definition is provided.

A – C

ABSCAM
An FBI undercover operation conducted from 1978 to 1980 in which agents posed as representatives of a fictional Arab sheikh offering bribes to public officials. The operation resulted in the conviction of one U.S. senator (Harrison Williams, D-NJ) and six members of the U.S. House of Representatives on bribery and conspiracy charges. The name is a contraction of "Abdul scam," referring to the fictitious sheikh. It was the first major FBI sting operation targeting members of Congress. See Chapter 10.
Bribery
The offering, giving, receiving, or soliciting of something of value (money, gifts, favors, employment) in exchange for an official action. Under federal law (18 U.S.C. § 201), bribery of a public official requires proof of a corrupt intent and a quid pro quo; an explicit exchange of a thing of value for a specific official act. Bribery is distinguished from campaign contributions, which are legal if given without an explicit corrupt agreement. The line between the two has been narrowed by the Supreme Court's McDonnell v. United States (2016) decision. See Chapter 18.
Campaign Finance
The system of laws, regulations, and practices governing how political campaigns are funded. Federal campaign finance is regulated by the Federal Election Commission (FEC) under the Federal Election Campaign Act (FECA) and subsequent legislation. The system includes contribution limits (how much can be given), disclosure requirements (who gave what), and restrictions on sources (corporations, unions, foreign nationals). See Chapter 16 for a comprehensive overview.
COINTELPRO
An acronym for "Counter Intelligence Program," a series of covert (and frequently illegal) FBI operations conducted from 1956 to 1971 under Director J. Edgar Hoover. COINTELPRO targeted domestic political organizations deemed subversive, including civil rights groups, antiwar movements, the Black Panther Party, and the Socialist Workers Party. Methods included infiltration, wiretapping, planting false evidence, inciting violence between groups, and blackmail. The program was exposed by the Church Committee in 1975 and is considered one of the most significant examples of institutional corruption in federal law enforcement history. See Chapter 8.
Conflict of Interest
A situation in which a public official's personal financial interests, family relationships, or other private concerns could improperly influence their official duties. Federal conflict of interest laws (18 U.S.C. §§ 202–209) prohibit officials from participating in matters in which they have a personal financial interest. Conflicts of interest are not inherently criminal, they may be resolved through recusal or divestiture, but become corrupt when the official acts on the conflict rather than disclosing and mitigating it.
Corruption
In this report, "corruption" is defined broadly as the misuse of public office for private gain, or the subversion of public institutions for personal, political, or financial benefit. This includes both criminal conduct (bribery, fraud, extortion) and non-criminal but documented abuses (conflicts of interest, revolving-door exploitation, regulatory capture). The definition is consistent with academic standards used by Transparency International, the World Bank, and the DOJ Public Integrity Section.

D – F

Dark Money
Political spending by organizations that are not required to disclose their donors. In practice, this primarily refers to spending by 501(c)(4) "social welfare" organizations and 501(c)(6) trade associations, which can engage in political advertising, voter mobilization, and contributions to Super PACs without revealing who funds them. The term was popularized by journalist Jane Mayer in her 2016 book Dark Money. See Chapter 16.
Embezzlement
The theft or misappropriation of funds or property by a person to whom they were entrusted. In the public corruption context, embezzlement involves government officials diverting public funds, property, or resources to personal use. It differs from bribery in that no external party need be involved; the official simply takes what was entrusted to them. Examples include officials using government credit cards for personal purchases, diverting contract payments to personal accounts, or billing for services never rendered.
Emoluments
Compensation or benefits received for holding office. The Emoluments Clause of the U.S. Constitution (Article I, Section 9) prohibits federal officeholders from accepting gifts, payments, or titles from foreign governments without congressional consent.
Ethics Committee
A committee established within a legislative body to investigate and adjudicate allegations of ethics violations by its members. In Congress, the House Committee on Ethics and the Senate Select Committee on Ethics are the relevant bodies. They can investigate, censure, reprimand, or recommend expulsion of members, but they cannot bring criminal charges. State legislatures and city councils often have equivalent bodies, though their powers and independence vary dramatically. Ethics committees are frequently criticized for being toothless, members are reluctant to sanction their colleagues, but they remain the primary internal accountability mechanism for legislators.
Extortion
The use of threats, intimidation, or coercion to obtain money, property, or official action. In the public corruption context, extortion under color of official right (the Hobbs Act, 18 U.S.C. § 1951) is one of the most commonly charged federal corruption statutes. It covers situations where a public official demands or accepts payment in exchange for performing (or refraining from) official acts. Unlike bribery, which requires a corrupt agreement between two parties, extortion focuses on the official's use of their position to coerce the payment.
FARA (Foreign Agents Registration Act)
A federal law enacted in 1938 requiring individuals who lobby or conduct public relations in the United States on behalf of foreign governments, political parties, or foreign principals to register with the DOJ and disclose their activities and compensation. FARA was originally designed to counter Nazi propaganda but has been applied more broadly since the 2016 election. Enforcement was historically lax, only seven criminal cases between 1966 and 2015, but has increased significantly in recent years. See Chapter 15.
FISA (Foreign Intelligence Surveillance Act)
A 1978 federal law that established procedures for the surveillance and collection of foreign intelligence information, including wiretapping and electronic monitoring of foreign agents and suspected spies. FISA created the Foreign Intelligence Surveillance Court (FISC), a secret court that approves surveillance warrants. In the corruption context, FISA is relevant because it has been used to surveil individuals later prosecuted for corruption (including several FARA-related cases) and because the secrecy of FISC proceedings raises due process concerns.
FOIA (Freedom of Information Act)
A federal law enacted in 1966 (5 U.S.C. § 552) that gives the public the right to request access to records from federal government agencies. FOIA is one of the most important tools for investigating corruption, allowing journalists, researchers, and citizens to obtain government documents. Agencies may withhold records under nine exemptions (including classified information, trade secrets, and law enforcement records), and delays of months or years are common. All 50 states have equivalent public records laws, though the scope of access varies widely.
Fraud
The intentional use of deception to obtain money, property, or some other advantage. In the public corruption context, the most relevant fraud statutes are mail fraud (18 U.S.C. § 1341), wire fraud (18 U.S.C. § 1343), and honest services fraud (18 U.S.C. § 1346). Mail and wire fraud are broadly applicable and are the most commonly charged federal statutes in white-collar cases. Honest services fraud specifically targets schemes to deprive the public of the "intangible right of honest services" from public officials.

G – I

Gerrymandering
The practice of drawing electoral district boundaries to give one political party an unfair advantage. While not always illegal, gerrymandering can constitute corruption when district lines are drawn to protect specific incumbents, dilute the voting power of minority communities, or lock in one-party rule regardless of voter preferences. The term dates to 1812, when Massachusetts Governor Elbridge Gerry approved a district so oddly shaped that a newspaper cartoonist compared it to a salamander. The Supreme Court ruled in Rucho v. Common Cause (2019) that federal courts cannot review partisan gerrymandering claims, leaving regulation to state courts and legislatures.
Grand Jury
A group of citizens (typically 16–23) empowered to investigate potential criminal conduct and determine whether sufficient evidence exists to issue an indictment (a formal charge). Unlike a trial jury, a grand jury does not determine guilt or innocence. Grand jury proceedings are secret; witnesses testify without their attorneys present, and the standard of proof is "probable cause," which is significantly lower than the "beyond a reasonable doubt" standard at trial. In the corruption context, grand juries are the primary mechanism for issuing federal indictments against public officials.
Honest Services Fraud
A federal crime (18 U.S.C. § 1346) defined as a scheme to defraud the public of the "intangible right of honest services" from a public official or corporate officer. This statute is the primary federal tool for prosecuting corruption that does not involve a traditional bribery quid pro quo. The Supreme Court narrowed its scope in Skilling v. United States (2010), holding that honest services fraud covers only bribery and kickback schemes, not other forms of self-dealing or conflicts of interest.
Impeachment
A formal charge of misconduct brought against a government official by a legislative body. Under the U.S. Constitution, the House of Representatives has the sole power to impeach federal officials (Article I, Section 2), and the Senate has the sole power to try impeachments (Article I, Section 3). Impeachment is analogous to an indictment; it is a charge, not a conviction. Removal from office requires a two-thirds vote of the Senate. Three presidents have been impeached by the House (Andrew Johnson, Bill Clinton, and Donald Trump, who was impeached twice). None was convicted by the Senate. One president (Richard Nixon) resigned before an impeachment vote.
Indictment
A formal written accusation of a crime, issued by a grand jury. An indictment means that a grand jury found sufficient evidence (probable cause) to charge a person with a crime. It does not mean the person is guilty. Federal indictments require the concurrence of at least 12 of the 16–23 grand jurors. The common observation that "a grand jury would indict a ham sandwich" (attributed to Judge Sol Wachtler) reflects the low threshold required and the one-sided nature of grand jury proceedings.
Inspector General (IG)
An independent official within a government agency charged with detecting and preventing waste, fraud, abuse, and corruption. The Inspector General Act of 1978 established IGs in most major federal agencies. IGs have the power to conduct audits, investigations, and inspections, and to issue reports with findings and recommendations. They cannot bring criminal charges but can refer cases to the DOJ for prosecution. IG reports are among the most important primary sources for documenting corruption. The independence of IGs has been periodically challenged by administrations seeking to remove or sideline inspectors who produce unfavorable findings.

K – O

Kickback
A payment made to a person who has facilitated a transaction or appointment, typically as a percentage of the value involved. In the corruption context, a kickback usually involves a government official steering a contract to a specific company, which then pays the official a percentage of the contract value. Kickbacks differ from bribery in that the payment flows from the transaction rather than preceding it. The Anti-Kickback Act (41 U.S.C. §§ 8702–8707) specifically prohibits kickbacks in connection with government contracts.
Lobbying
The act of attempting to influence government decisions, typically by communicating with legislators, regulators, or other government officials on behalf of a client or interest. Lobbying is a constitutionally protected activity under the First Amendment. Under the Lobbying Disclosure Act (LDA) of 1995, individuals who spend 20% or more of their time lobbying for a client must register and disclose their activities and compensation. See Chapter 15 for a comprehensive analysis.
Money Laundering
The process of making illegally obtained money appear legitimate by passing it through a complex series of transactions. Under federal law (18 U.S.C. §§ 1956–1957), money laundering involves conducting financial transactions with the proceeds of unlawful activity, knowing the transactions are designed to disguise the source, ownership, or control of the funds. In the corruption context, money laundering charges are frequently added to bribery, fraud, and embezzlement cases when officials or their co-conspirators attempted to conceal illicit payments.
Obstruction of Justice
Any act that corruptly impedes, influences, or obstructs an official proceeding, investigation, or the administration of justice. Covered by a family of federal statutes (18 U.S.C. §§ 1501–1521), obstruction includes destroying evidence, intimidating witnesses, lying to investigators, and tampering with proceedings. In the corruption context, obstruction charges are frequently paired with underlying corruption charges when officials attempt to cover up their conduct. Obstruction is the "cover-up" factor in the Corruption Severity Score.

P – R

PAC / Super PAC
PAC (Political Action Committee): An organization that pools campaign contributions from members and donates those funds to campaigns for or against candidates, ballot initiatives, or legislation. Traditional PACs are limited in how much they can contribute to candidates ($5,000 per candidate per election).

Super PAC: Officially known as an "independent expenditure-only committee," created after Citizens United v. FEC (2010) and SpeechNow.org v. FEC (2010). Super PACs can raise and spend unlimited money from any source (individuals, corporations, unions) but are prohibited from donating directly to or coordinating with campaigns. In practice, the coordination prohibition is widely considered unenforceable. See Chapter 16.
Patronage
The practice of appointing political supporters, friends, or allies to government positions regardless of their qualifications. Patronage was the dominant staffing system in American government for most of the 19th century, formalized under President Andrew Jackson's "spoils system." The Pendleton Civil Service Reform Act (1883) began replacing patronage with merit-based hiring for federal positions, though patronage persists in many forms: ambassadorial appointments, political appointees in executive agencies, and local government positions in machine-politics cities. See Chapter 2.
Perjury
The crime of deliberately making false or misleading statements while under oath, or in a sworn written statement. Under federal law (18 U.S.C. § 1621), perjury requires proof that the false statement was material (relevant to the proceeding), was made under oath, and was made willfully (the person knew it was false). Perjury charges are common in corruption cases, typically arising when officials lie during investigations or congressional testimony about their corrupt conduct.
Plea Bargain
A negotiated agreement between a prosecutor and defendant in which the defendant agrees to plead guilty to a lesser charge or to one of multiple charges in exchange for a reduced sentence or the dismissal of other charges. Plea bargains resolve approximately 90–95% of federal criminal cases.
Public Integrity Section (PIN)
A section within the Criminal Division of the U.S. Department of Justice responsible for overseeing the federal effort against corruption by government officials at all levels; federal, state, and local. Established in 1976 in the wake of Watergate, PIN has nationwide jurisdiction over public corruption cases and publishes annual statistics on corruption convictions. See Chapter 18.
Qualified Immunity
A judicial doctrine that shields government officials, including law enforcement officers, from civil liability for actions taken in their official capacity unless they violated "clearly established" constitutional rights. Created by the Supreme Court beginning with Pierson v. Ray (1967) and expanded in Harlow v. Fitzgerald (1982), qualified immunity is not found in any statute. The "clearly established" standard requires that a prior court decision must have addressed facts sufficiently similar to the case at hand. In practice, this makes it extremely difficult to hold individual officers civilly liable for misconduct. See Chapter 18.
Quid Pro Quo
Latin for “something for something.” In corruption law, refers to an exchange in which an official action is taken in return for a benefit. The Supreme Court in McDonnell v. United States (2016) significantly narrowed the definition of what constitutes an “official act” for corruption prosecution purposes.
Racketeering / RICO
The Racketeer Influenced and Corrupt Organizations Act (RICO, 18 U.S.C. §§ 1961–1968) is a federal law enacted in 1970 that allows prosecution and civil penalties for racketeering activity performed as part of an ongoing criminal enterprise. Originally designed to combat organized crime, RICO has been increasingly used in public corruption cases to prosecute officials who participated in a "pattern of racketeering activity"; at least two acts of criminal conduct (called "predicate acts") within a 10-year period. RICO allows prosecutors to charge leaders of corrupt enterprises with the crimes their subordinates committed, making it a powerful tool against systemic corruption.
Regulatory Capture
A phenomenon in which a regulatory agency, created to act in the public interest, instead advances the commercial or political interests of the industry it is supposed to regulate. The concept was formalized by economist George Stigler in 1971. Capture can occur through the revolving door (hiring industry insiders as regulators), information asymmetry (agencies depending on industry for expertise), and career incentives (regulators seeking future employment in industry). See Chapter 17.
Revolving Door
The movement of individuals between positions in government and jobs in the private sector, particularly in the industries the individual regulated or oversaw while in government. The revolving door creates corruption risks because: (1) the prospect of a lucrative future industry job can influence an official's current regulatory decisions, and (2) former officials can leverage their government relationships and inside knowledge on behalf of private clients. Federal law imposes "cooling-off periods" on some officials, but enforcement is uneven and the restrictions are narrowly drawn. See Chapter 15.

S – W

Spoils System
A practice in which a political party, after winning an election, fills government positions with its own supporters, friends, and allies. The term derives from Senator William Marcy's 1832 defense of the practice: "To the victor belong the spoils." Formalized under President Andrew Jackson, the spoils system dominated American government from the 1830s until the passage of the Pendleton Civil Service Reform Act in 1883. Vestiges persist in the appointment of political officials at all levels of government. See Chapter 2.
Subpoena
A legal order requiring a person to appear to testify (subpoena ad testificandum) or to produce documents (subpoena duces tecum). In the corruption context, subpoenas are issued by grand juries, courts, congressional committees, and regulatory agencies to compel the production of evidence. Failure to comply with a subpoena can result in contempt charges. Congressional subpoenas have been a key tool in corruption investigations, though enforcement of congressional subpoenas against executive branch officials has been contested.
Whistleblower
An individual who reports illegal activity, fraud, corruption, or threats to public safety within an organization to authorities or the public. Federal whistleblower protections exist under multiple statutes, including the Whistleblower Protection Act (1989), the Sarbanes-Oxley Act (2002), and the Dodd-Frank Act (2010). Protections vary significantly: federal employees have broader protections than private-sector workers, and state-level protections range from robust to minimal. Whistleblowers have been critical to exposing corruption throughout American history, from Deep Throat (Mark Felt, Watergate) to Sherron Watkins (Enron) to the anonymous whistleblower in the first Trump impeachment. Despite legal protections, retaliation against whistleblowers remains common.
