Background & current role
Josh Gruenbaum was appointed Commissioner of the General Services Administration’s Federal Acquisition Service in 2025. GSA’s biography describes a background in restructuring, mergers and acquisitions, governance and investing.
On January 16, 2026, the White House named Gruenbaum and Aryeh Lightstone as senior advisors to the Board of Peace, responsible for day-to-day strategy and operations supporting the President’s Gaza plan. This page labels that assignment separately from his GSA office.
TrumpsMouth tracks the public record of both roles without assuming that activity in one portfolio establishes authority in another. Specific claims, negotiations or procurement controversies will be added only with source material sufficient to separate allegation, response and documented record.
