People
Former Deputy Assistant Attorney General Matt Hanson represents companies and individuals in government investigations by Congress, the Securities and Exchange Commission (SEC), the Department of Justice (DOJ), and other federal and state regulators. Matt also counsels clients on related disclosure and regulatory issues and helps conduct internal investigations to assess potential liability before the government becomes involved. He is a partner in King & Spalding’s Special Matters & Government Investigations practice.
Matt has particular experience with congressional inquiries—both responding to large-scale investigations and helping manage low-key initial requests. He has prepared senior executives for dozens of public hearings and managed responses to high-pressure House and Senate inquiries. Many high-profile congressional matters are accompanied by parallel investigations from other regulators, and Matt has deep experience representing clients in the tech, finance, and healthcare spaces, among other industries, facing such enterprise-threatening regulatory investigations. As a former reporter, Matt also helps clients manage broader impacts that investigations can have on their business.
Matt served nearly three years with DOJ’s Office of Legislative Affairs, most recently as a Deputy Assistant Attorney General. While in that role, Matt handled sensitive congressional requests and investigations directed at the Department and prepared senior leadership for testimony, including the Attorney General. He worked closely with other DOJ leadership offices and with DOJ’s National Security Division, the FBI, and the Drug Enforcement Administration, managing the Department’s engagement with Congress on issues, cases, and legislation affecting national security. He engaged regularly with House and Senate committees focused on the judiciary, financial services, intelligence, and healthcare, as well as with House and Senate leadership staff.
Matt also has over a decade of private practice experience representing clients facing securities enforcement and other tech and white-collar investigations. Matt’s clients include public companies, social media platforms, emerging tech companies, broker-dealers, investment advisers, and financial institutions, as well as corporate officers and other individuals. He previously helped lead the firm’s work for clients in the digital assets space.
Before becoming a lawyer, Matt worked as a news reporter covering bonds, structured finance, and other financial markets.
