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.

Currently he oversees NAHB’s litigation efforts where he develops NAHB’s legal strategies and provides litigation support to local home builders associations. He also supports NAHB’s lobbyists, and coordinates with NAHB’s regulatory staff to identify government activities (i.e. regulations or guidance documents) that may require involvement by the Litigation Department. One of the first cases Tom worked on for NAHB was United States v. Deaton where NAHB argued that the Deaton wetland was not a “water of the United States.” 20 years later we were proven right.

Executive Vice President, The Heritage Foundation
Derrick Morgan has thirty years’ experience in business, government, law, politics, and policy and now serves as the Executive Vice President of The Heritage Foundation, overseeing policy and government relations.
In business, Morgan led the American Fuel and Petrochemical Manufacturers’ (AFPM) advocacy efforts, testified before Congress, and wrote and spoke widely on fuels issues including energy security, fuel prices, and regulatory burdens such as the Renewable Fuel Standard. At AFPM and on the Hill, he opposed electric vehicle mandates and subsidies and warned against conventional wisdom, predicting EV adoption would be far from universal.
In government, law, and politics, Morgan served in all three branches of government including four senators and one representative in roles including campaign aide, counsel to the Senate Republican Policy Committee, and chief of staff to Senator Ben Sasse of Nebraska. In addition, he served as assistant, special counsel, and staff secretary for Vice President Richard B. Cheney, where he traveled frequently with the Vice President as a member of his senior staff and was the final substantive stop for all papers, remarks, and statements. As a leadership staffer for Senator Thune on Capitol Hill, Morgan helped organize opposition to “Card Check” legislation that would have eliminated the secret ballot for workers in union elections and harmful climate legislation like cap-and-trade and carbon taxes. Following law school and between stints at Gibson, Dunn & Crutcher LLP, Morgan clerked for a federal district judge in Texas.
In policy, Morgan previously worked at Heritage, first as Chief of Staff to the organization’s Founder and President, Ed Feulner, and later as Vice President of Domestic Policy. At Heritage, Morgan was privileged to fight “comprehensive” immigration reform that included amnesty for illegal immigrants when the Beltway political class overwhelmingly supported it.
A longtime movement leader on energy, the economy, and immigration, he has appeared on radio and television outlets including Fox News, Fox Business, Newsmax, CNN, CNBC, and C-SPAN. His commentary has been published widely including in The Wall Street Journal, The New York Times, Los Angeles Times, Politico, Real Clear Politics, and USA Today.
Morgan received his undergraduate degree at the University of Texas at Dallas, where he gave the honors commencement address and later received a Distinguished Alumni Award. He holds a JD from The Georgetown University Law Center.
