A coalition of 16 states is going after the Trump administration over the cancellation of more than $1 billion in “bipartisan mental health funding” for students in low-income and rural communities — filing a lawsuit Monday that accuses the government of breaching grant agreements and violating federal regulations, “leaving schools and students to suffer the consequences,” the states say.

Attorneys general in California, Colorado, Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, Michigan, New Mexico, New York, Nevada, Oregon, Rhode Island, Washington and Wisconsin are suing the Department of Education for, in their words, “illegally cutting congressionally approved funding” for mental health programs in K-12 schools.

“The tragic events of the Uvalde school shooting prompted a bipartisan Congress to dramatically increase the historical funding levels for the programs and ensure future funds would be available through the Bipartisan Safer Communities Act,” the AGs wrote in a 48-page complaint filed in the Western District of Washington state.

“On or about April 29 … the Department decided to discontinue program grants based on an alleged conflict with the current Administration”s priorities,” the complaint later says. “The Department implemented its Non-Continuation Decision by sending boilerplate notices to plaintiffs claiming that their grants conflicted with the Trump Administration’s priorities and would not be continued.”

According to the states, department officials intend to repurpose the program funds “based on new priorities.” The department issued its notices to plaintiffs’ grantees, including state education agencies, local education agencies and institutes of higher education. The department provided “little to no insight into the basis for the discontinuance,” while allegedly destroying projects “years in the making,” the states say.

“Defendants’ unlawful actions have already caused and will cause immediate and devastating harm to plaintiffs,” the complaint charges.

“Starting this fall, many schools in Plaintiff states will no longer be able to reliably provide mental health services to the kids that need them most,” it says. “These discontinuances threaten the very purpose of these Programs — to protect the safety of our children by permanently increasing the number of mental health professionals providing mental health services to students in low-income and rural schools.”

The states say that if the cuts are not rescinded, local educational agencies will be forced to lay off “the very same professionals” they recruited and hired to provide mental health services using program funds. Institutes of higher education will be affected too, the states allege, with financial support for graduate student internships going out the window as well.

“As a result, hundreds of graduate students will make the difficult choice whether they should enter or continue a graduate program no longer able to offer tuition assistance — drying up a workforce pipeline Congress recognized needed development,” the complaint claims.
