House Republicans are investigating a leaked glossary of Diversity, Equity and Inclusion (DEI) terms passed around the National Security Agency, which they say provides a “deeply troubling” look into the “hiring and contracting processes” of the intelligence organization.

Reps. Mike Waltz (R-Fla.) and Jim Banks (R-Ind.) wrote in a Tuesday letter to NSA Director Paul Nakasone that the glossary includes “incoherent” definitions of terms concerning gender, race and capitalism that could “harm national security.”
