Rob Cary is a Fellow of the American College of Trial Lawyers and Co-Chair of the firm’s Lawyer Liability Practice Group. Rob’s trial practice is varied.  In 2018, for example, Rob’s first-chair trial experience included a jury acquittal in a criminal trial in Oregon and the successful defense of two businesses in a civil trial in Delaware. Rob also has extensive experience representing companies and individuals in government investigations and has conducted investigations for audit committees of publicly traded companies.     

Rob is well known for his representation of the late U.S. Senator Ted Stevens, who was indicted on ethics charges less than 100 days before he was to stand for re-election. Senator Stevens was exonerated when it was revealed that the prosecution had hidden evidence from the defense.  The American Lawyer described Williams & Connolly’s work on the case as “one of the best criminal defense performances in memory, resulting in a heightened scrutiny of prosecutors that will affect the Justice Department for years to come.”

With client permission and encouragement, Rob wrote a book about the Stevens case.  Bob Woodward of The Washington Post describes the book Not Guilty: The Unlawful Prosecution of U.S. Senator Ted Stevens as a “public service…a shocking, deeply sobering tale that every American worried about the concentration of power in the federal government should read and study.”  Barry Scheck, co-director of the Innocence Project, describes it as a “riveting account from one of our country’s great lawyers.”  Retired federal judge Nancy Gertner describes it as “an extraordinarily important book, a must read not only for lawyers, but federal judges.”

Rob, together with his colleagues Craig Singer and Simon Latcovich, has also authored Federal Criminal Discovery, the first book devoted entirely to the topic of discovery in federal criminal cases.  The American Bar Association describes the book as an “invaluable resource for judges, academics, prosecutors, and defense lawyers.”

Rob has represented clients in a number of high-stakes appeals.  He has also represented clients in many criminal and civil investigations conducted by government agencies, including the Food and Drug Administration, the Securities and Exchange Commission, and federal and state prosecutors.
