Zachor Legal Institute is a legal think tank and advocacy organization that aims to combat boycott, divestment and sanctions (BDS) against Israel; antisemitic activities; and anti-Israel movements in the United States in the commercial, university, and government sectors. 1


Zachor Legal Institute employs both offensive and defensive strategies to combat antisemitism and BDS initiatives. This includes preventing the spread of boycott, divestment and sanctions (BDS) and antisemitic activities in academic institutions, government agencies, businesses, and unions, and suing individuals and organizations that are funding or participating in antisemitic and BDS activities. 2

Zachor Legal Institute collaborates with like-minded organizations in its efforts to influence both federal and state level policy. In 2022, Zachor Legal was one of 28 organizations that signed a petition to top officials at the Department of State, the Federal Bureau of Investigation, and the Department of Justice requesting that the BDS movement be monitored, investigated, and legally challenged as necessary. The petition described the BDS movement as hate groups that promote violence against Jews and claimed that the BDS movement in the U.S. has financial ties to terrorist organizations like Hamas and the Popular Front for the Liberation of Palestine. Other organizations that signed this petition include Americans Fighting Antisemitism, the Endowment for Middle East Truth, and the Middle East Forum. 3

Zachor Legal Institute researches and publishes legal research related to BDS and the First Amendment. Zachor Legal also participates in court challenges supporting state laws that would prevent taxpayer funds from being used to support BDS-affiliated organizations. While working on these court proceedings, Zachor Legal found that the American Civil Liberties Union (ACLU) has a history of supporting anti-Semitism and BDS through its affiliation with the Council on American-Islamic Relations. Zachor Legal claims that it is hypocritical for the ACLU to align with BDS groups while simultaneously fighting to end discrimination against those in the LGBT, Black, and Asian communities. In its 2021 report “Not Your Parents’ American Civil Liberties Union,” Zachor Legal also found that the ACLU defended anti-Israel organizations, lobbied against state and federal anti-BDS laws, and employed staff with current or past affiliations to organizations that support BDS. 4
