A seasoned trial lawyer and former federal prosecutor, David I. Miller practices in the areas of white collar criminal defense, government and internal investigations, securities and commodities enforcement, related complex civil litigation, cryptocurrency, and national security. Previously, David served for five years as an Assistant US Attorney in the Southern District of New York (SDNY), over half that time as a member of the Securities and Commodities Fraud Task Force. He also served as a terrorism prosecutor with the Department of Justice in Washington, DC, as a Special Assistant US Attorney in the Eastern District of Virginia, as an Assistant General Counsel for the Central Intelligence Agency, and as a securities and commercial litigation attorney in private practice.

David has more than two decades of litigation experience, including in white collar criminal defense; securities and commodities litigation and enforcement proceedings; corporate internal investigations (including those implicating the Foreign Corrupt Practices Act); complex commercial litigation; Bank Secrecy Act and anti-money laundering issues; cryptocurrency issues; forfeiture litigation; compliance counseling; and national security matters. David has conducted 10 jury and bench trials, several of which were multi-defendant trials, including securities and accounting fraud trials, with guilty verdicts secured for nearly all defendants on all counts. As an appellate advocate, David has briefed and argued several appeals before the US Court of Appeals for the Second Circuit. The Legal 500 US notes that David has been praised by industry insiders for his “sharp mind, strategic thinking and client-focused advice,” and he has been recognized as a New York Super Lawyer in the area of white collar criminal defense.

As an Assistant US Attorney in SDNY’s Securities and Commodities Fraud Task Force, David was responsible for investigating and prosecuting a wide range of securities and commodities fraud offenses, including insider trading, investment adviser fraud, offering fraud, accounting fraud, options backdating, market manipulation, reverse mergers, credit default swap schemes, hedge fund improprieties, and Ponzi schemes. David handled multiple insider trading matters and was part of a team of prosecutors leading the government’s investigation and prosecution of Operation Perfect Hedge, which has resulted in the conviction of more than 80 individuals for insider trading offenses since 2009. As part of his duties, he worked closely with, and coordinated parallel civil enforcement proceedings with, the SEC, CFTC, FINRA, and other regulatory agencies. While David was an Assistant US Attorney, he also prosecuted numerous other criminal offenses, including bank, mail, wire, healthcare, and tax fraud; credit card fraud and identity theft; money laundering; obstruction of justice and false statements; terrorism offenses; export control violations; and narcotics, firearms, and robbery offenses. Additionally, he has experience with asset forfeiture issues, having litigated several criminal and civil forfeiture proceedings.

David previously served as a terrorism prosecutor with the US Department of Justice’s Counterterrorism Section in Washington, DC, where he investigated and prosecuted several high-profile terrorism-related cases through trial. He also served as a Special Assistant US Attorney in the Eastern District of Virginia, where he investigated and prosecuted white collar, firearms, narcotics, and gang-related offenses through trial.  David’s career includes his time as an Assistant General Counsel for the Central Intelligence Agency, where he litigated and prosecuted cases on the CIA’s behalf (including classified and state secrets matters); was the assigned CIA representative to the prosecution team in United States v. I. Lewis (“Scooter”) Libby (D.D.C.); regularly advised senior CIA officials; and represented the CIA at high-level, interagency meetings implicating sensitive national security issues.  Before joining government service in 2005, David spent six-and-a-half years as a securities, complex commercial and bet-the-company litigator with two large law firms in New York.

David’s experience in defending allegations of financial, securities, and commodities fraud is invaluable for clients—including broker-dealers, hedge funds, private equity funds, investment companies and advisers, banks, and public and private companies—facing risks of government investigation, regulatory enforcement, and related civil litigation, as well as other matters that require internal investigations, including Foreign Corrupt Practices Act and Bank Secrecy Act/Anti-Money Laundering compliance. To this end, David represents clients before DOJ, several US Attorney's Offices, SEC, CFTC, FINRA and other self-regulatory organizations, state attorneys general offices, and other state regulators and enforcement authorities. He is also an asset for clients facing issues implicating digital currencies, national security, international clients doing significant business in the United States, and clients with cybersecurity and privacy-related issues.  David is also a technical advisor for a popular television drama series.
