In short: Originally enacted to expose foreign subversion, the Foreign Agents Registration Act (FARA) spent decades in obscurity. Today, it has evolved into a high-stakes tool for tracking international influence in American politics. From Cold War espionage to modern lobbying scandals, discover how this transparency mandate became a central pillar of national security.

Enacted in 1938, the Foreign Agents Registration Act was a direct response to the rise of Nazi influence in the United States. Congress sought to counter foreign propaganda by requiring individuals acting on behalf of foreign principals to disclose their relationships, activities, and financial compensation. Initially, the law focused on criminal prosecution, but it struggled to gain traction; between 1945 and 1955, only two indictments were brought. The Department of State, which held early enforcement authority, famously resisted the responsibility, leading to a transfer to the Department of Justice in 1942.

A major shift occurred in 1966, when the Act was narrowed to focus on political lobbying rather than general propaganda. This change required the government to prove that an agent acted under the direction or control of a foreign power, which created a higher burden of proof. Consequently, criminal prosecutions became rare, and the government increasingly relied on civil injunctive remedies to encourage voluntary compliance. By 2015, there had been only seven criminal prosecutions under the amended law, none of which resulted in a conviction.

The law’s profile changed dramatically after 2017, as enforcement intensified against officials connected to the Trump administration. This era saw high-profile cases, such as the 2020 guilty plea of Elliott Broidy for secret lobbying and the 2024 arrest of Linda Sun for acting as an undisclosed agent of China. Today, the FARA Unit of the Department of Justice manages over 500 active registrations, a 30 percent increase since 2016. While critics call for reform, the law remains a primary mechanism for navigating the tension between the First Amendment’s right to petition and the persistent, centuries-old anxiety regarding foreign interference in American democracy.
