John D. Cooke is a trial lawyer and former federal prosecutor who represents clients in high-stakes civil litigation, criminal and regulatory matters, and corporate investigations.

Government Experience
Prior to joining the Bergeson firm, John was an Assistant U.S. Attorney for twelve years, practicing in the Northern District of Illinois as well as in the Northern Districts of California and New York. During his tenure as a federal prosecutor, he led complex investigations, prosecutions, and trials in a range of matters, including fraud, money laundering, cybercrime, public corruption, violent crime, and violations of the Racketeer Influenced and Corrupt Organizations Act (RICO). As a result of his prosecution and trial of leaders of a violent street gang for RICO violations, John was tapped to coordinate the U.S. Attorney’s Office’s racketeering investigations amid an upswell in violent crime in Chicago.

In addition to his experience in federal criminal litigation, John represented the United States in civil litigation, including fraud matters under the False Claims Act (FCA) and employment disputes. In representing the federal government as a plaintiff, John obtained more than $60 million in settlements for his client. He also successfully defended the Medicare Act’s administrative appeals process against constitutional challenge.

Trial Acumen
John has tried a dozen cases to verdict, both criminal and civil, and has successfully briefed and argued cases before United States Courts of Appeals. His criminal and civil experience in government uniquely qualifies him to represent clients across the spectrum of legal risk, in all phases of litigation, and at trial. John’s practice includes:

  • Business litigation
  • Complex commercial litigation
  • Corporate control disputes
  • Employment disputes
  • Investigations
  • Post-closing disputes
  • Securities litigation and class actions
  • Shareholder derivative actions
  • White-collar defense

Before joining the U.S. Attorney’s Office, John was an attorney at two nationally recognized litigation firms in Silicon Valley. There, his work focused on business, securities, and intellectual property litigation and on investigations by the Securities and Exchange Commission, in technology, financial services, and other industries.
