Mr. Luiz A. Santos was sworn in as Inspector General (IG) of the Architect of the Capitol (AOC) in July 2025. In this role he is responsible for conducting, coordinating, and supervising independent audits and investigations of AOC programs, operations, and construction projects to prevent and deter fraud, waste, and abuse. He also provides leadership and coordination and recommends policies to promote economy, efficiency, and effectiveness. As Inspector General, Mr. Santos also keeps the AOC and the Congress fully and currently informed about problems and deficiencies in the administration of AOC programs and operations.

Prior to joining the AOC, Mr. Santos served as Acting Inspector General of the U.S. Department of Labor, Office of Inspector General (DOL-OIG) beginning in January 2025, and as Deputy Inspector General since January 2022. In these positions, he oversaw more than $56 billion in annual federal funding for critical programs such as unemployment insurance, worker safety and health, training and reemployment services, pension and health care benefits, wage and hour standards, and economic statistics. He was also responsible for overseeing nearly $1 trillion in funding for critical pandemic emergency programs. He directed criminal investigations into labor racketeering, corruption, and the influence of organized crime in employee benefit plans, internal union affairs, and labor-management relations. His office also collaborated with law enforcement partners on human trafficking investigations.

Under his leadership, the DOL-OIG achieved significant investigative and audit outcomes, closing approximately 1,600 investigations that resulted in more than 2,600 indictments, 2,000 convictions and approximately $1.3 billion in monetary results. He also oversaw more than 150 high-impact audits, reviews, and evaluations that identified over $75 billion in funds that could be put to better use.

Active in the Inspector General community, Mr. Santos currently serves as a U.S. delegate to the International Public Sector Fraud Forum (IPSFF), representing the Council of the Inspectors General on Integrity and Efficiency (CIGIE) alongside experts from the Five Eyes intelligence alliance to exchange leading practices on combating public sector fraud.
