From Guns.com:

The Giffords Law Center, in conjunction with the American Federation of Teachers and the Southern Poverty Law Center, filed suit against the department in a D.C. federal court on Wednesday.

The groups argue that Education Secretary Betsy DeVos recently moved to green light the use by local school districts of federal grant dollars from the Student Support and Academic Enrichment Program, designed to help struggling schools, to instead purchase guns and training for teachers and faculty, an allegation DeVos denies.
