Former Acting Assistant Attorney General, United States Department of Justice; Partner, Winston & Strawn LLP
Jonathan “Jon” Brightbill is a trial and appellate lawyer in Winston’s Washington, D.C. office, and a partner in the firm’s Litigation and White Collar, Regulatory Defense, and Investigations Practices. He represents public and private companies, corporate officers, and other individuals across white collar, regulatory defense, and government and internal investigation matters and rulemaking challenges, as well as complex commercial disputes, citizen suits, and class actions. His commercial litigation experience encompasses business disputes, false advertising, consumer protection and fraud, FCA, and extensive class action defense work; antitrust and unfair competition matters; and intellectual property litigation, such as trademarks, patents, and trade secrets.
Jon served as the Nation’s lead environmental civil and criminal enforcement official and litigator, as Acting Assistant Attorney General for the Environment & Natural Resources Division (“ENRD”) of the U.S. Department of Justice (DOJ). Jon led ENRD’s 425 lawyers, overseeing 6,500 active matters and managing an annual budget of more than $150 million. Jon brings highly experienced executive leadership from among the most senior level of DOJ on white collar and regulatory enforcement, as well as on federal policymaking and rulemaking development and challenges. He speaks with authority on government decision-making processes, and the arguments and perspectives that move regulators and enforcers, best advising and positioning clients to deal with challenges.
Jon argued many of the government’s most significant cases during his time with the DOJ. This included the Navigable Waters Protection Rule and Clean Water Rule Repeal (10th Cir., district courts), the Affordable Clean Energy Rule and Clean Power Plan Repeal (D.C. Cir), defense of EPA actions on pesticide tolerances under FIFRA and the FDCA (9th Cir. en banc), among numerous others. Jon represented the United States in trial courts in both enforcement and defensive cases, including federal enforcement action against Jeffrey Lowe and the Tiger King Park, of Netflix fame, securing a first-of-its-kind injunction for violations of the Endangered Species Act and Animal Welfare Act. Jon directed the litigation and briefing of scores of additional federal cases nationwide, covering all of the major environmental and natural resources statutes, such as the Clean Air Act, the Clean Water Act, FIFRA (pesticides), FDCA (food safety), TSCA (toxics), CERCLA (land remediation), RCRA (waste), National Environmental Policy Act, Federal Land Policy and Management Act, and numerous other land- and resource-management statutes.
Jon has unmatched experience litigating legal and technical issues relating to climate change. He argued in the courts of appeals, including the D.C. Circuit, regarding the most significant climate change regulations by EPA, as well as the preemptive scope of the Clean Air Act. Jon also litigated climate change-related credit and trading schemes and international agreements in district court. During Jon’s time in leadership at ENRD, it successfully defeated one of the most wide-ranging lawsuits regarding climate change to date—obtaining a stay pending interlocutory appeal and dismissal just weeks before a scheduled three-month trial on federal government liability for climate change.
An accomplished trial lawyer, prior to working at DOJ, Jon was a partner in the Washington, D.C. office of another global law firm. He not only represents clients in court, but creatively counsels corporations on balancing business needs and realities with a broad range of litigation risks and compliance obligations. Jon is also an Adjunct Professor at Georgetown University Law Center. He served on the American Bar Association’s E-Discovery Working Group for Bankruptcy Practice, and was a frequent lecturer for District of Columbia Bar Association Continuing Legal Education Programs.

He leads its environmental practice group, a unique initiative that draws broadly from PLF’s expertise and success in property rights and separation of powers litigation. Over the years, Damien has represented hundreds of landowners and property rights advocates to defend their liberties against heavy-handed and unwarranted environmental and land-use regulation. His litigation experience includes Sackett v. U.S. Environmental Protection Agency, a groundbreaking decision in which the U.S. Supreme Court upheld the right of landowners to challenge Clean Water Act compliance orders issued by EPA, and Contoski v. Norton, PLF’s successful effort to force the federal government to make good on its promise to delist the bald eagle from the Endangered Species Act.
Besides litigation, Damien has written academic articles on a variety of subjects, including the Endangered Species Act, the Clean Water Act, greenhouse gas torts, the duty to rescue, and international water law. He has appeared on a variety of television and radio programs and has been quoted in The New York Times, The Wall Street Journal, Harper’s Magazine, and The Economist, among other publications.
He obtained his law degree magna cum laude from the University of San Diego School of Law, and his undergraduate degree magna cum laude from Georgetown University. While at USD, he was a research assistant for Professor Bernard Siegan, a leading constitutional theorist and advocate for property rights and economic liberty. Immediately prior to joining PLF, Damien clerked for Judge (and former PLF attorney) Victor Wolski of the United States Court of Federal Claims. Damien credits the mentoring and examples of Professor Siegan and Judge Wolski for his decision to pursue a career in liberty-based public interest litigation.
Damien lives in Sacramento with his wife, two young sons, four chickens, and a cat named Princess. In his off hours he enjoys stamp collecting, Gregorian chant, and martinis—preferably at the same time.
Former Acting Assistant Attorney General, United States Department of Justice; Partner, Winston & Strawn LLP
Jonathan “Jon” Brightbill is a trial and appellate lawyer in Winston’s Washington, D.C. office, and a partner in the firm’s Litigation and White Collar, Regulatory Defense, and Investigations Practices. He represents public and private companies, corporate officers, and other individuals across white collar, regulatory defense, and government and internal investigation matters and rulemaking challenges, as well as complex commercial disputes, citizen suits, and class actions. His commercial litigation experience encompasses business disputes, false advertising, consumer protection and fraud, FCA, and extensive class action defense work; antitrust and unfair competition matters; and intellectual property litigation, such as trademarks, patents, and trade secrets.
Jon served as the Nation’s lead environmental civil and criminal enforcement official and litigator, as Acting Assistant Attorney General for the Environment & Natural Resources Division (“ENRD”) of the U.S. Department of Justice (DOJ). Jon led ENRD’s 425 lawyers, overseeing 6,500 active matters and managing an annual budget of more than $150 million. Jon brings highly experienced executive leadership from among the most senior level of DOJ on white collar and regulatory enforcement, as well as on federal policymaking and rulemaking development and challenges. He speaks with authority on government decision-making processes, and the arguments and perspectives that move regulators and enforcers, best advising and positioning clients to deal with challenges.
Jon argued many of the government’s most significant cases during his time with the DOJ. This included the Navigable Waters Protection Rule and Clean Water Rule Repeal (10th Cir., district courts), the Affordable Clean Energy Rule and Clean Power Plan Repeal (D.C. Cir), defense of EPA actions on pesticide tolerances under FIFRA and the FDCA (9th Cir. en banc), among numerous others. Jon represented the United States in trial courts in both enforcement and defensive cases, including federal enforcement action against Jeffrey Lowe and the Tiger King Park, of Netflix fame, securing a first-of-its-kind injunction for violations of the Endangered Species Act and Animal Welfare Act. Jon directed the litigation and briefing of scores of additional federal cases nationwide, covering all of the major environmental and natural resources statutes, such as the Clean Air Act, the Clean Water Act, FIFRA (pesticides), FDCA (food safety), TSCA (toxics), CERCLA (land remediation), RCRA (waste), National Environmental Policy Act, Federal Land Policy and Management Act, and numerous other land- and resource-management statutes.
Jon has unmatched experience litigating legal and technical issues relating to climate change. He argued in the courts of appeals, including the D.C. Circuit, regarding the most significant climate change regulations by EPA, as well as the preemptive scope of the Clean Air Act. Jon also litigated climate change-related credit and trading schemes and international agreements in district court. During Jon’s time in leadership at ENRD, it successfully defeated one of the most wide-ranging lawsuits regarding climate change to date—obtaining a stay pending interlocutory appeal and dismissal just weeks before a scheduled three-month trial on federal government liability for climate change.
An accomplished trial lawyer, prior to working at DOJ, Jon was a partner in the Washington, D.C. office of another global law firm. He not only represents clients in court, but creatively counsels corporations on balancing business needs and realities with a broad range of litigation risks and compliance obligations. Jon is also an Adjunct Professor at Georgetown University Law Center. He served on the American Bar Association’s E-Discovery Working Group for Bankruptcy Practice, and was a frequent lecturer for District of Columbia Bar Association Continuing Legal Education Programs.
Jon served as an appellate clerk for the Honorable D. Brooks Smith, U.S. Court of Appeals for the Third Circuit, after graduating magna cum laude from the Georgetown University Law Center. He worked in state government as an Executive Policy Specialist for air, waste, land remediation, and radiation matters at the Pennsylvania Department of Environmental Protection.
Dr. Dasgupta served as Assistant Secretary for Trade and Economic Security, responsible for a comprehensive national security portfolio. His duties included oversight of the Committee on Foreign Investment in the United States (CFIUS), Team Telecom, the Forced Labor Enforcement Task Force (FLETF), Information and Communications Technology and Services (ICTS), Arctic security initiatives, the Icebreaker Collaboration Effort (ICE) Pact, and related trade matters. Sohan Dasgupta also served as political head of the Millennium Challenge Corporation (MCC), supporting U.S. foreign policy and national security objectives. Previously, he had served as Deputy General Counsel of the U.S. Department of Homeland Security (DHS).
Dr. Dasgupta holds a JD from the University of California, Berkeley, where he was elected to the Order of the Coif; a PhD in international trade and arbitration from the University of Cambridge; MSc from the University of Oxford; and BA in Economics–Operations Research and History from Columbia University. He commenced his legal career with clerkships on the U.S. Court of Appeals for the Ninth Circuit and the U.S. District Court for the Southern District of West Virginia.
Dr. Dasgupta has addressed the Hungarian, Romanian, and Guatemalan parliaments, and has spoken at the invitation of Members of the U.S. Congress, the British Parliament, the European Union Parliament, the Congress of the Philippines, and the Legislative Assembly of El Salvador.
