Our Commitment to Diversity
David C. Rybicki

David Rybicki is the co-leader of the firm's White Collar Defense and Investigations practice group. His practice focuses on high-stakes white collar defense, internal and government-facing investigations, regulatory enforcement defense, congressional investigations, compliance assessments and risk management, and corporate counseling. 

Drawing on his experience as a federal prosecutor, as a senior official in the Criminal Division of the US Department of Justice (DOJ), and as US Senate Judiciary Committee chief counsel, David represents corporations, audit committees, boards, and executives in matters involving corporate fraud, foreign bribery, the False Claims Act, securities and financial fraud, international money laundering, and in cross-border issues such as extradition and mutual legal assistance. He has deep and wide-ranging experience representing clients in criminal, civil, and regulatory investigations and enforcement matters involving the DOJ and its Fraud Section, FCPA Unit, Market Integrity and Major Frauds Unit, Money Laundering and Asset Forfeiture Section (MLARS), National Security Division (NSD), Drug Enforcement Administration (DEA), Civil Frauds Section, Consumer Protection Branch, Office of International Affairs (OIA), and US Attorney’s Offices throughout the country; SEC headquarters in Washington, D.C., and the SEC’s regional offices; the US Department of Treasury Office of Foreign Assets Control (OFAC) and Treasury Office of Inspector General (OIG); the US Department of Commerce Bureau of Industry and Security (BIS); Internal Revenue Service Criminal Investigation (IRS-CI); the US Food and Drug Administration Office of Criminal Investigations (FDA-OCI); the Department of Homeland Security (DHS); Customs and Border Protection (CBP); and state attorneys general throughout the country. 

He also represents companies and individuals at all stages of investigations launched by House and Senate committees—from responding to information requests and subpoenas to preparing senior corporate executives for testimony at committee hearings. He has recently represented clients in inquiries involving the following committees: House Committee on Oversight and Accountability; House Energy and Commerce Committee; House Select Subcommittee on the Coronavirus Crisis; House Select Committee on the 6 January US Capitol Attack; House Judiciary Committee and its Antitrust Subcommittee; House Homeland Security and Government Affairs Committee; House Select Committee on Strategic Competition between the United States and the Chinese Communist Party; Senate Commerce Committee; Senate Committee on Health, Education, Labor, and Pensions (HELP); Senate Committee on Finance; as well as inquiries from individual members of the House and Senate.  

From 2017-2020, David served in the DOJ’s Criminal Division as Acting Principal Deputy Assistant Attorney General and Deputy Assistant Attorney General, the second- and third-highest ranking positions in the Division. In these senior leadership roles, he led the investigation, prosecution, and coordination of the Division’s most significant national and cross-border matters and initiatives involving corporate criminal enforcement, the Foreign Corrupt Practices Act (FCPA), securities and accounting fraud, the Bank Secrecy Act (BSA), cybercrime and cryptocurrencies, OFAC sanctions enforcement, transnational organized crime, healthcare fraud, civil and criminal RICO, public corruption, and gaming law.

Prior to joining the Criminal Division, David served as counselor to the Attorney General of the United States and advised on the DOJ's top criminal enforcement initiatives. This work included revision of the Department's corporate enforcement and compliance policies, extension of the FCPA Pilot Program, “Going Dark” and other significant cybersecurity policy matters, Mutual Legal Assistance Treaties (MLATs), and creation of the Department's new civil asset forfeiture policies and regulatory guidelines.

In 2018, the Attorney General appointed David to serve on the United States Sentencing Commission, where he represented the DOJ with respect to all aspects of federal sentencing law and policy, including the drafting of amendments to the Federal Sentencing Guidelines for corporate fraud and other white collar crimes.

Earlier in his career, David served for six years as an Assistant United States Attorney (AUSA) in the United States Attorney’s Office for the District of Columbia. As an AUSA, David conducted grand jury investigations and prosecuted and tried a broad range of criminal matters. David also defended federal agencies and officials in complex civil litigation involving administrative, constitutional, and regulatory law, tort claims, and employment discrimination. He has first-chaired more than twenty jury and bench trials and argued frequently before the United States Court of Appeals for the D.C. Circuit and the D.C. Court of Appeals. 

David has also worked in several senior roles on the United States Senate Judiciary Committee. As a chief counsel and earlier as counsel to Sen. Charles Grassley, he served as a senior legal, policy, and legislative advisor on matters involving cybersecurity, data encryption and privacy, intellectual property, bankruptcy restructuring, and criminal justice reform. He also advised on oversight and investigation of the DOJ, DHS regarding national security, immigration, whistleblower claims, and other consequential public policy matters.

David is a frequent speaker and panelist on issues pertaining to corporate compliance programs, AML/CFT, healthcare fraud, and the Federal Sentencing Guidelines. He was previously a member of the American Bar Association's Criminal Justice Section Council and White Collar Dialogue Group, and is currently a member of the Edward Bennett Williams Inn of Court, an invitation-only professional organization specializing in white collar practice.

He is a graduate of Stanford Law School, where he served as Executive Editor of the Stanford Law Review. He holds an M.Phil. from Cambridge University, where he was a Gates Cambridge Trust Scholar, and a B.A., magna cum laude, from Yale College. David clerked for the Honorable Edith H. Jones of the U.S. Court of Appeals for the Fifth Circuit.
