Background

Overview

Transparency International U.S. (TIUS) is the American affiliate of Transparency International, an international anti-corruption coalition of over 100 chapters worldwide that practice research, advocacy, and campaigning to expose corruption, push for greater government transparency, and lobby for anti-corruption legislation and processes. ¹ TIUS works to expand and enforce American anti-corruption laws around the world. ²

TIUS is fiscally sponsored by the Fund for Constitutional Government, an advocacy organization focused on exposing and addressing government corruption in the United States. ⁴

Disaccreditation of Predecessor

In 2017, Transparency International USA was disaccredited as an affiliate of Transparency International on the grounds that Transparency International USA was excessively influenced by major business interests. At the time, Transparency International USA’s board was dominated by corporate lawyers, and the group had recently received grants from Deloitte, Google, Citigroup, ExxonMobil, Fluor, General Electric, Lockheed Martin, Marsh & McLennan, PepsiCo, PricewaterhouseCoopers, Raytheon, Realogy, Tyco, and Johnson & Johnson. According to Corporate Crime Reporter, Transparency International USA was “seen in the United States as a corporate front group, funded by multinational corporations — the same multinationals that corrupt the U.S. political system.” The disaccreditation was catalyzed by Transparency International USA giving Bechtel, one of its donors, a transparency award. ^{5 3}

In 2020, Transparency International formed Transparency International U.S. as its new American affiliate. ¹

Activities

Transparency International U.S. supports efforts to enforce international anti-bribery laws, particularly the 1977 Foreign Corrupt Practices Act, which criminalized Americans paying bribes in foreign countries. TIUS has called the law the “crown jewel in the U.S.’s fight against global corruption.” In 2023, TIUS helped pass the Foreign Extortion Prevention Act, which criminalized foreign officials demanding bribes from American companies. ^{6 7}

In February 2025, TIUS criticized the second Trump administration for issuing an executive order pausing enforcement of the Foreign Corrupt Practices Act until U.S. Attorney General Pam Bondi issued new guidelines. ⁷

TIUS supports efforts to enforce international money laundering laws. In December 2025, TIUS wrote a letter to the U.S. Congress encouraging the creation of stricter laws to prevent money laundering with cryptocurrencies. In November, TIUS wrote a letter encouraging the U.S. Congress to strengthen anti-money laundering provisions in the GENIUS Act, a bill regulating stablecoin cryptocurrencies. ⁸

TIUS supports efforts to encourage the development and integrity of democratic institutions in foreign countries and the United States. In January 2025, shortly after the second inauguration of President Donald Trump, TIUS sent a letter to the president urging him to take a “strong ethics pledge,” which included a five-year post-government employment ban on lobbying, a two-year ban on communicating with former agency and senior White House staff with the intent to influence, a prohibition on “golden parachutes” for government employees, and the appointing of an ethics czar to oversee the administration. ⁹

TIUS supports enhanced regulation of the international arms trade, which is largely the responsibility of the U.S. as the largest arms exporter in the world. ¹⁰

TIUS supports enhancing the American engagement and influence abroad as a leader of international “integrity, transparency, and accountability.” TIUS encourages American support and leadership for the International Monetary Fund, World Bank, and United Nations. ¹¹
