US SB889

Establishes a federal grant program for States, Indian Tribes, and local governments to implement extreme risk protection order (ERPO) laws that allow courts to temporarily remove firearms from individuals found to pose a danger to themselves or others

Requires grant recipients to allocate 25-70% of funds for law enforcement training on safe, equitable ERPO administration, including training on bias, domestic violence protocols, mental health crisis intervention, and social service referrals

Amends federal firearms law (18 U.S.C. § 922) to prohibit firearm possession or receipt by individuals subject to ERPOs issued after a hearing with notice and opportunity to participate, adding these orders to the National Instant Criminal Background Check System

Mandates due process protections including written notice, opportunity to be heard within 30 days, and court hearings with preponderance of evidence standard; ex parte orders allowed only until a full hearing occurs

Requires full faith and credit between States and Tribes for ERPO enforcement, takes effect 180 days after enactment, and authorizes annual reporting on petition numbers, demographics, and outcomes
