Washington, D.C. – SECIL Law PLLC continues its strategic growth with the addition of David E. Carney as Partner and B. Jonathan Haskin as Associate, strengthening the firm’s core focus on white-collar defense, government investigations, and complex regulatory matters. The arrival of David, in particular, marks a significant expansion of the firm’s senior-level enforcement and investigations capabilities.
David E. Carney brings more than twenty-five years of experience representing corporations and senior executives in high-stakes enforcement actions, internal investigations, and complex civil litigation. Over the course of his career, David has guided clients through some of their most sensitive matters involving the U.S. Department of Justice, Securities and Exchange Commission, Consumer Financial Protection Bureau, and other federal and state regulators. He is widely recognized for his ability to navigate the intersection of legal risk, regulatory scrutiny, and business realities-drawing on a deep understanding of how government agencies investigate, charge, and resolve cases.
“David’s arrival is a significant milestone in the firm’s continued growth,” said John Rowley, Partner at SECIL Law. “He brings decades of frontline experience navigating the most challenging enforcement matters and investigations. That level of judgment and credibility is exactly what our clients expect when the stakes are highest, and it meaningfully strengthens our platform.”
David’s experience spans the full lifecycle of enforcement and investigation matters, from early risk assessments and internal reviews through litigation, negotiations, and resolution. In addition to his defense work, he regularly advises clients on compliance program design, remediation, and anti-corruption diligence—areas that are increasingly central to enforcement decision making and outcomes.
Joining the firm alongside David, B. Jonathan Haskin adds to SECIL Law’s growing bench of attorneys trained in litigation, investigations, and regulatory oversight. Jonathan supports the firm’s white-collar defense and regulatory matters, drawing on experience in state and federal litigation, including assisting in drafting complex federal appeals, as well as hands-on exposure to enforcement bodies, including the Financial Industry Regulatory Authority’s Department of Enforcement and the U.S. Department of Justice Civil Division.
“As we continue to build a durable investigations and enforcement practice, it’s critical that we invest at both the senior and emerging levels,” said Adriaen Morse, Partner at SECIL Law. “David brings seasoned leadership and strategic depth, while Jonathan represents the next generation of lawyers trained in government processes and trial-ready advocacy. Together, they reflect how we are growing the firm thoughtfully and deliberately.”
With these additions, SECIL Law continues to position itself as a premier white-collar litigation and government investigations boutique built around former prosecutors, enforcement lawyers, and trial-tested advocates. The firm’s growth reflects a long-term strategy focused on credibility with regulators, senior-level judgment, and the ability to guide clients through the most consequential investigations and enforcement actions they face. As regulatory and prosecutorial activity continues to expand across industries, SECIL Law remains committed to deepening its government experience and expanding its capacity to handle the most complex and high-risk matters.
