Matthew Krueger, a former United States Attorney, is a skilled litigator who represents clients facing government enforcement and complex litigation challenges. Matt also helps clients proactively by advising on regulatory compliance and conducting internal investigations. He offers clients well-honed judgment, drawn from experience with high-stakes matters in private practice and multiple Justice Department roles, including civil False Claims Act enforcement, white-collar criminal prosecutions, and appellate litigation in the Solicitor General’s Office. Matt’s background enables him to help clients on a broad range of enforcement and litigation matters, with particular focus on health care issues; cyber security and data privacy; and complex trials and appeals.

Before joining Foley, Matt served as the United States Attorney for the Eastern District of Wisconsin after receiving unanimous Senate confirmation. As the chief federal law enforcement officer in 28 counties, Matt supervised all criminal and civil litigation involving the United States. Under his leadership, the office successfully prosecuted high-profile cases involving national security, cybercrime, public corruption, healthcare fraud, financial crime, PPP fraud, violent crime, civil rights and other offenses. Among other accomplishments, Matt formed a dedicated healthcare fraud unit and increased its focus on data analytics, resulting in a substantial rise in False Claims Act and criminal prosecutions. Matt also led efforts with the FBI to advise businesses regarding the risks of cyber intrusions.

As United States Attorney, Matt interfaced regularly with DOJ components and other federal and state enforcement agencies. He served on the Attorney General’s Advisory Committee’s (AGAC) Healthcare Fraud Working Group and Civil Rights Subcommittee. Matt chaired the White Collar Working Group of the AGAC’s Native American Issues Subcommittee, working with inspectors general from multiple federal agencies to reduce grant fraud.

Matt also served for nearly five years as an Assistant U.S. Attorney in the same district, in both the civil and criminal divisions. In the civil division, Matt handled False Claims Act investigations and litigation involving health care fraud, the Anti-Kickback Statute, the Stark Law, and various government contracting issues. He later served as the criminal healthcare fraud coordinator and prosecuted cases from investigation through appeal involving healthcare fraud, tax fraud, investment fraud, bank fraud, government contracting fraud, money laundering, national security and other offenses. Matt has successfully tried multiple cases and argued numerous appeals.

Previously, Matt practiced trial and appellate litigation at an elite law firm in Washington, D.C., where he litigated cases involving securities claims, antitrust, unfair competition, trademark disputes, environmental enforcement and other complex matters. Matt also served as a Bristow Fellow in Solicitor General’s Office helping represent the government before the Supreme Court and federal courts of appeals. He began his career by clerking for the Honorable Paul V. Niemeyer of the U.S. Court of Appeals for the Fourth Circuit.
