S. 4685 — Ending Double Dealing Act of 2026

This section prohibits the Department of Defense from entering into, renewing, or extending contracts, grants, or other transactional agreements with covered consultancies after the date of enactment. It requires bidders to disclose any contracts, grants, or financial awards from covered entities in the prior five years and any ongoing relationships, mandates contract termination for cause plus suspension and debarment proceedings for up to five years upon nondisclosure, and allows a covered consultancy to submit a certification ending its status if it severs ties with covered entities. The section also directs the Secretary to issue implementing policies and guidance within 180 days and amend the Defense Federal Acquisition Regulation Supplement within one year.
