This bill, known as the Guarding U.S. Authority for Removal and Detention Act , aims to significantly enhance immigration enforcement capabilities and protect personnel involved in these operations. It amends the Posse Comitatus Act to authorize the use of National Guard forces for specific immigration-related duties, creating exceptions to the general prohibition on using military for domestic law enforcement, thereby broadening the scope of National Guard involvement in federal immigration matters. Specifically, the legislation permits National Guard members, whether on state or federal duty, to engage in the enforcement of immigration laws , including the apprehension and detention of unlawfully present aliens, and the execution of orders of removal. Additionally, it authorizes their use for border security operations , allowing for the deployment of National Guard personnel to assist in various aspects of immigration control and border management across the nation. Furthermore, the bill establishes a new federal crime for assaulting immigration enforcement officers , covering personnel from U.S. Immigration and Customs Enforcement, U.S. Customs and Border Protection, other federal agencies, and state or local law enforcement officers actively assisting federal immigration operations. The penalties for these assaults are substantial, with basic offenses carrying imprisonment of 5 to 20 years; if bodily injury results, the term increases to 10 to 30 years, and if death occurs, offenders face life imprisonment or the death penalty, underscoring the severity of these offenses and the intent to deter such acts.
