Define to Defeat Act of 2024

This bill requires U.S. federal agencies and courts to use the International Holocaust Remembrance Alliance (IHRA) definition of antisemitism in specific contexts. It mandates that federal departments include this definition in anti-discrimination training (Section 3), directs courts to provide it in jury instructions for cases involving antisemitism (Section 4), and requires agencies to consider antisemitism as a motivating factor in civil rights investigations involving Jewish identity (Section 5). The law applies to existing civil rights enforcement under laws like the Civil Rights Act of 1964 and the Voting Rights Act. It does not create new penalties or alter existing protections but standardizes how antisemitism is recognized in federal processes.
