Adds to existing law to provide for cooperation with federal authorities, to provide for cooperation with immigration detainers, to provide for the crime of unlawful presence of a dangerous illegal alien, and to provide for the crime of smuggling a dangerous illegal alien.

The Idaho Immigration Cooperation and Enforcement Act, or Idaho ICE Act, fulfills Idaho's commitment to support the Trump administration in the identification, detainment, and deportation of dangerous illegal aliens found in Idaho. President Trump has identified a strategic priority of removing from the United States those illegal aliens who "threaten the safety or security of the American people", particularly those involved in criminal cartels, foreign gangs, criminal organizations, and human trafficking and smuggling. See Executive Order of the President, Protecting the American People Against Invasion (Jan. 20, 2025). The Idaho ICE Act prohibits sanctuaries in Idaho, makes it unlawful for dangerous illegal aliens to be present in Idaho, and makes it unlawful for dangerous illegal aliens to be transported in to Idaho. Dangerous illegal aliens and smugglers, once apprehended, are then confined and Idaho authorities are required to cooperate with ICE for the deportation of the confined alien. The Idaho ICE Act also ensures law enforcement cooperates with federal immigration detainers. A 5-year sentencing enhancement is also imposed upon illegal aliens that commit dangerous crimes in Idaho. The Idaho ICE Act will increase the safety and security of Idaho's communities and highways.
