Executive Order Ends DEI Activities by Federal Contractors
President Trump signed an Executive Order on March 26, 2026, prohibiting racially discriminatory diversity, equity, and inclusion (DEI) activities by federal contractors. The order mandates contract clauses forbidding disparate treatment based on race or ethnicity in hiring, promotion, and other employment functions. Contractors are required to report violations, with noncompliance risking contract cancellation or penalties. The Office of Management and Budget is tasked with oversight, and agencies must monitor adherence. The Federal Acquisition Regulatory Council will issue implementing changes. The Department of Justice is authorized to pursue enforcement under the False Claims Act when warranted.

The study will assess UAS operational practices, airport interface processes, and physical infrastructure requirements for platforms under and above 55 pounds, including cargo operations.
