Define to Defeat Act of 2025

The Define to Defeat Act of 2025 would codify the International Holocaust Remembrance Alliance (IHRA) working definition of antisemitism as the standard for enforcing a set of federal civil rights laws. The bill requires federal agencies to embed the IHRA definition in their anti-discrimination training, requires courts to include the IHRA definition in jury instructions in cases involving antisemitism, and instructs agencies to consider antisemitic motivation when reviewing or deciding violations under covered civil rights laws (which include major civil rights and equal protection statutes, as well as hate-crime provisions). The act also clarifies that this definition is not an expansion of agency authority or a change to existing standards, and it preserves First Amendment protections. In short, the bill aims to create a uniform, official definition of antisemitism to guide enforcement across federal civil rights enforcement.
