Witness Security and Protection Grant Program Act of 2023

This bill establishes a federal grant program to help state and local governments protect witnesses in serious crime cases. It provides competitive grants (up to 75% federal funding) to jurisdictions with high rates of witness intimidation, homicide, violent crime, drug offenses, or organized crime, prioritizing areas lacking protection infrastructure. Grantees must report on their programs, and the Justice Department will develop and share best practices for witness safety, relocation, and financial assistance. The program is authorized for $30 million annually through 2027.
