Denver Public Schools became the first U.S. school district Wednesday to sue the Trump administration challenging its policy allowing ICE immigration agents in schools.

Colorado’s largest public school district argued in the federal lawsuit that the policy has forced schools to divert vital educational resources and caused attendance to plummet.

“DPS is hindered in fulfilling its mission of providing education and life services to the students who are refraining from attending DPS schools for fear of immigration enforcement actions occurring on DPS school grounds,” the lawsuit states.

The federal lawsuit against the Department of Homeland Security and Homeland Security Secretary Kristi Noem says the Trump administration hasn't provided “good reason” for rescinding the rules nor adequately considered or addressed the fallout.

Last month, President Donald Trump lifted longtime rules restricting immigration enforcement near sensitive locations, including schools. The announcement came as the new president seeks to make good on campaign promises to carry out mass deportations.

“Denver is standing up for its children and families and protecting the right of all children, regardless of their immigration status, to attend public schools," Elora Mukherjee, director of the Immigrants’ Rights Clinic at Columbia Law School, said in an email.

Denver Public Schools serve more than 90,000 students — about 4,000 of which are immigrants, according to the lawsuit, which cites 2023-2024 school year numbers. More than half of the students are Hispanic or Latinx.

The city of Denver has seen an increase in migrants recently. Since 2023, about 43,000 people have arrived in the city from the U.S. southern border, according to the lawsuit.

“Parents across Denver enroll their children in public schools believing that while at school, their children will be educated and enriched without fear the government will enforce immigration laws on those premises,” the lawsuit said.

The school district says it has had to devote a lot of time and resources to adding policies that keep students safe and training faculty and staff on how to respond to people claiming they are conducting immigration enforcement at schools.

Denver Public Schools also want to see DHS publish the directive publicly, saying that not being able to view the change in policy has impeded their ability to prepare for it, according to the lawsuit.

The Trump administration did not immediately respond to an email from The Associated Press seeking comment.
