Biography

John Irving brings nearly three decades of experience in white collar criminal defense, government investigations, and high-stakes congressional and corporate inquiries. A former federal prosecutor and trusted advisor within the U.S. Department of Justice and the Environmental Protection Agency, John is known for his calm under pressure, strategic clarity, and unwavering discretion.

His clients have included Members of Congress, senior executives, political appointees, and corporate entities navigating complex criminal, civil, and regulatory matters—including matters that have dominated national headlines. John’s practice today is defined by sophisticated representation in sensitive investigations, classified matters, and strategic crisis response—often involving multiple enforcement authorities.

John served for over a decade in the U.S. Department of Justice, including as an Assistant U.S. Attorney in Washington, D.C., where he prosecuted a wide range of criminal cases and appeared regularly in court. He later served as Counsel to two Deputy Attorneys General and as Counsel to the Assistant Attorney General of DOJ’s Environment and Natural Resources Division, advising on departmental policy and enforcement matters at the highest levels.

Prior to his tenure at DOJ, John served as Investigative Counsel to the (then-named) U.S. House Committee on Government Reform & Oversight and as an Associate Independent Counsel in the investigation of former HUD Secretary Henry Cisneros.

Before joining SECIL Law, John was a Partner at E&W Law, a boutique firm focused on environmental and white-collar litigation, and previously spent over a decade at Holland & Knight LLP in Washington, D.C. There, he was a key member of the firm’s White-Collar Defense, Investigations & Compliance team.

His private practice experience includes:

Representing a co-defendant in the Mar-a-Lago Special Counsel classified documents case.
Defense counsel in United States v. Peter Navarro, a high-profile case involving contempt of Congress and executive privilege.
Counsel to Rep. Scott Perry (R-PA) in matters involving the Speech or Debate Clause.

Jesse Panuccio

Partner, Boies Schiller Flexner LLP

Biography

Jesse, the former third-ranking official at the U.S. Department of Justice, helps clients with their most difficult litigation and regulatory issues─whether that means defending against an enforcement action, pursuing high-stakes litigation and appeals, navigating regulatory thickets at federal and state agencies, or crafting a comprehensive strategy to manage a crisis. He approaches these problems with the knowledge gained both from his broad private-practice experience and from having served at the highest levels of federal and state government.

Jesse has experience across a range of substantive and regulatory areas. He has sued the federal government and has also been one of its top law-enforcement officials; he has represented states and has also navigated their regulatory agencies on behalf of clients; and he has represented companies in business disputes, both as defendants and plaintiffs.

Before joining the firm, Jesse was the Acting Associate Attorney General at the United States Department of Justice. In that role, he oversaw the civil and criminal work of the Antitrust, Civil, Civil Rights, Environment and Natural Resources, and Tax Divisions. During Jesse’s tenure, the Associate’s office closely managed the Department’s most significant litigation, including matters involving large financial institutions, healthcare companies, automakers, energy companies, and state and local governments. In addition, Jesse served as Chair of DOJ’s Regulatory Reform Task Force and Vice Chair of DOJ’s Task Force on Market Integrity and Consumer Fraud. Jesse regularly provided legal and strategic advice to the highest-level decision makers in the federal government, including the Attorney General and Deputy Attorney General, general counsels across the spectrum of federal agencies, and White House officials.

Jesse served for three years as the secretary of Florida’s labor, economic-development, and land-use agency, the Florida Department of Economic Opportunity. Before that, he served as Governor (now Senator) Rick Scott’s general counsel.

Jesse maintains offices in both Washington D.C. and Florida. From Washington, he focuses on federal litigation and crisis management. In Florida, in addition to federal litigation, Jesse employs his knowledge of state government and regulation to help clients in courts across the state, from trial through the Florida Supreme Court.

Jesse currently serves on the Florida Supreme Court Judicial Nominating Commission, the body that provides the governor with nominees for appointment to the Florida Supreme Court. Jesse is also a fellow at the Center for the Study of the Administrative State at the Scalia Law School at George Mason University, where he writes and speaks about administrative law.

Biography

JUSTIN SAVAGE is a global co-leader of the firm’s Environmental, Health, and Safety practice and co-leads the Automotive and Mobility sector team, where he is a leading strategist for companies navigating the intersection of complex regulation, high-stakes litigation, and transformative industry change. For nearly three decades, he has led clients through their most consequential environmental, health, and safety (EH&S) disputes and mobility-sector challenges, earning a reputation as both a trusted counselor and a forceful advocate in the courtroom and the boardroom. A core part of Justin’s practice also focuses on regulatory strategy and market entry, advising emerging technology companies, new market entrants, and established industry leaders on launching new products, technologies, and business models. He regularly counsel clients in emerging fields such as robotics and AI on engaging with regulators, anticipating enforcement and compliance risk, and building defensible regulatory strategies that support growth rather than slow it.

Clients praise Justin as “an excellent litigator… strategically clever and creative… attentive, thoughtful and willing to go above and beyond” (Chambers USA 2025). Chambers USA has ranked him for Band 1 for Environment in District of Columbia (2017–2025) and Band 3 for Transportation: Road (Automotive) in USA—Nationwide (2023–2025).

Justin has won some of the most closely watched EH&S and transportation disputes of the past two decades and guided companies through crises where business continuity, brand reputation, and regulatory survival were on the line. His leadership has been repeatedly recognized: he is a three-time Law360 Environmental “MVP” (2018, 2024, 2025) and a Lawdragon “500 Global Leaders in Crisis Management” (2025-2026). He is the first call for companies facing bet-the-company challenges.

Justin’s clients concentrate in heavily regulated industries, including auto and mobility, aviation, chemicals, data centers, energy, mining, and refining. Justin litigates and counsels across the spectrum of U.S. environmental, transportation, and administrative laws, including the Clean Air Act (Title I, mobile sources, and fuels), incident response, RMP, NHTSA, Clean Water Act, TSCA, CSB investigations, APA claims, FOIA litigation, NEPA, and the Safe Drinking Water Act.

Prior to joining Sidley, Justin served for nearly a decade at the Environmental Enforcement Section of the U.S. Department of Justice, where he led teams in several multi-billion dollar enforcement cases. In his career, Justin has regularly taught on a range of environmental and litigation topics. For several years, Justin served as an instructor at the Justice Department’s National Advocacy Center where he taught hundreds of Assistant U.S. Attorneys and other agency lawyers on topics that included trial advocacy and evidence. Since rejoining private practice, Justin has served eight times as a faculty member for the American Law Institute’s Environmental Litigation program. He also lectured on a range of litigation and trial topics for bar associations and organizations, including serving as an instructor for the FAA on trial advocacy.
