Examples of Ms. Clarke’s experience include:

Ms. Clarke’s experience representing the United States as an attorney with the Department of Justice and the United States Attorney’s office for the District of Maryland and Eastern District of Virginia enriches her approach to litigation and environmental enforcement matters.  Following graduation from law school, she was selected into the U.S. Attorney General’s Honor Program at the Department of Justice where she served as a trial attorney with the Environmental Crimes Section and the Natural Resources Section.  She handled a broad array of cases – both criminal and civil in federal district courts across the country.  Based on her distinguished performance, Ms. Clarke was invited to serve as a Special Assistant to the Assistant Attorney General for the Environment & Natural Resources Division where she worked on leading civil and criminal matters impacting national environmental policy.  During her time with the government, she developed close relationships within the Department of Justice and other federal agencies, which endure to this day. 

Ms. Clarke also served as a federal prosecutor with the United States Attorney’s Office for the District of Maryland and the Eastern District of Virginia where she gained additional trial experience in a variety of criminal and civil matters, including healthcare fraud, defense procurement fraud, employment, toxic tort, and medical malpractice.  Ms. Clarke was selected to serve as a counsel in the Department of Justice’s Office of Professional Responsibility where she lead internal investigations into professional misconduct allegations against Assistant United States Attorneys, and other high-level officials.  In addressing concerns regarding federal prosecutor’s abuse of their charging discretion, Ms. Clarke developed a keen understanding of how prosecutors approach investigations and the factors that influence their charging decisions.  She also possesses a deep knowledge of the ethical guidelines against which federal prosecutors are measured.
