Category: Private Citizen — Corporate Director Role: Independent Director, Microsoft Corporation (MSFT) Board Tenure: 2023 – present Committee Memberships: Governance and Nominating Committee Profile Type: Board Member Accountability — Anchor B (Documented Organizational Leadership)

Basis for Inclusion: Mark A. L. Mason holds a documented governance role as an independent director of Microsoft Corporation, which made documented political donations to Trump-aligned entities while the corporation faced regulatory and policy decisions directly affecting its financial interests. Mason’s concurrent role as CFO of Citigroup — a systemically important global bank subject to extensive federal regulatory oversight under the Trump administration — creates a governance profile of cross-sector significance. This profile documents the factual governance relationship, not the subject’s personal political views.

Subject Classification: Private Citizen / Corporate Director. Board membership is a matter of public record (SEC filings, proxy statements). This profile documents only the governance role and its connection to documented corporate political activity.

What is NOT the basis for inclusion: Mason’s personal political opinions, party affiliation, public statements, or any protected speech are NOT the basis for inclusion. The basis is solely the documented directorial role and its fiduciary connection to corporate political spending documented in the parent corporate donor profile.

Biographical Overview

Mark A. L. Mason has been Chief Financial Officer of Citigroup, one of the world’s largest financial institutions with approximately $2.4 trillion in total assets, since 2019. At Citi, he previously served as CEO of Citi Private Bank, CEO and COO of Citi Holdings, and head of strategy and M&A for Global Wealth Management. He joined Citigroup in 2001.

Mason is one of the most senior Black executives in global financial services. His concurrent CFO role at a systemically important financial institution subject to Federal Reserve, OCC, and FDIC oversight — whose regulatory trajectory is shaped by the Trump administration’s deregulatory agenda — creates a significant cross-institutional governance profile. Mason joined the Microsoft board in 2023.

He holds a B.S. in Economics from Hampton University and an MBA from Harvard Business School.
