Define to Defeat Act of 2025

This bill seeks to establish a uniform definition of antisemitism for the enforcement of various federal civil rights laws. It specifically adopts the International Holocaust Remembrance Alliance (IHRA) working definition of antisemitism, including its examples, to ensure consistent application across federal departments and agencies. The legislation's findings emphasize that using a single, clear definition is crucial for effective monitoring, investigation, and policymaking against anti-Jewish hate. To implement this, the bill requires federal departments and agencies to include the IHRA definition in all anti-discrimination training and education materials. Furthermore, in any federal criminal or civil action involving antisemitism, courts must incorporate this definition into jury instructions . Federal agencies are also directed to consider whether potential civil rights violations, based on an individual's actual or perceived Jewish identity, were motivated by antisemitism during their reviews and investigations. The legislation clarifies that its provisions do not expand the authority of federal agencies, alter existing standards for determining civil rights violations, or diminish any rights protected under current law, including those guaranteed by the First Amendment to the Constitution.
