The Department of Justice, under President Trump’s directive, has announced an aggressive crackdown on sanctuary cities, with plans to investigate and potentially prosecute state and local officials who resist federal immigration laws. Acting Deputy Attorney General Emil Bove issued a memo warning that officials obstructing lawful immigration enforcement could face criminal charges.

The policy marks a sharp departure from the Biden administration’s approach, prioritizing the removal of undocumented immigrants accused of crimes and prosecuting officials who fail to comply with federal detainer requests. Sanctuary jurisdictions—areas limiting cooperation with immigration authorities—are the primary focus. A newly formed Sanctuary Cities Enforcement Working Group will spearhead investigations.

The DOJ memo reinstates the most serious offense policy for immigration violations, potentially leading to mandatory minimum sentences or harsher penalties. This approach reflects President Trump’s broader commitment to curbing illegal immigration and upholding what his administration views as the rule of law.

Critics argue that targeting local officials could lead to constitutional challenges, with sanctuary city leaders calling the move an overreach. Despite opposition, the administration emphasizes that these measures are vital to public safety and national security, framing the crackdown as a response to voter demands for stronger immigration enforcement.
