U.S. Court of Appeals, D.C. Circuit
Judge Williams practiced law in New York City (at the firm of Debevoise Plimpton and as an Assistant U.S. Attorney) and then taught law at the University of Colorado Law School from 1969 to 1986, with visiting years at UCLA, SMU, and the University of Chicago (where he was also a fellow in law and economics). He was appointed to the U.S. Court of Appeals for the D.C. Circuit in 1986. His most recent book is a biography of Vasily Maklakov, The Reformer: How One Liberal Fought to Preempt the Russian Revolution (Encounter Books, 2017).
Chair, Issues & Appeals, Hunton Andrews Kurth LLP
The former Solicitor General of West Virginia, Mr. Lin has been on the front lines of many precedent-setting cases in appellate courts across the country, including in a US Supreme Court victory that George Will called “the court’s most severe rebuke of a president” since the Truman administration. Having argued more than 60 appeals, he brings to clients a well-honed ability to identify the most persuasive issues for appeal and a practiced understanding of how best to frame complex legal questions in appellate courts.
With experience in the private sector and multiple branches of government, Mr. Lin’s practice has spanned a wide range of issues, including major questions of constitutional and administrative law at the federal and state levels. On behalf of more than two dozen states, he won a stay from the US Supreme Court of the EPA’s Clean Power Plan. Described by the New York Times as an “unprecedented” order, the stay was the first time the Supreme Court had ever put a regulation on hold before review by a federal appeals court. In that same case, Elbert argued before the en banc DC Circuit in an historic proceeding that one commenter quoted in E&E News compared to “the NBA All-Star Game.” At the state level, Elbert led the effort that persuaded the West Virginia Supreme Court of Appeals to overturn an injunction of the state’s right-to-work law.
In 2013, Mr. Lin was appointed the Solicitor General of West Virginia. During his four-and-a-half year tenure, he served as a member of the Attorney General’s senior management team, oversaw all civil and criminal appeals, and argued nearly two dozen cases in federal and state appellate courts. He authored more than twenty-five briefs in the US Supreme Court and more than forty-five formal Opinions of the Attorney General.
Earlier in his career, Mr. Lin served as a trial attorney in the Federal Programs Branch of the US Department of Justice’s Civil Division, where he received a Special Service Award. He has also been a law clerk at all three levels of the federal judiciary: for Justice Clarence Thomas on the US Supreme Court; for Judge William H. Pryor Jr. on the US Court of Appeals for the Eleventh Circuit; and for Senior Judge Robert E. Keeton on the US District Court for the District of Massachusetts.
Mr. Lin speaks regularly on a wide variety of topics, including constitutional law, administrative law, environmental law, state and federal relations, the US Supreme Court, and appellate practice. He has testified before Congress, and has spoken at the national conventions of the American Bar Association, the Association of Corporate Counsel, the National Asian Pacific American Bar Association, the Federalist Society, Americans for Prosperity, and the American Legislative Exchange Council. He is an elected member of the American Law Institute, a public member of the Administrative Conference of the United States, and a fellow of the American Academy of Appellate Lawyers.
Mr. Lin is admitted to practice in the following federal courts: the Supreme Court of the United States; the First, Second, Third, Fourth, Fifth, Sixth, Seventh, Eighth, Ninth, Eleventh, D.C., and Federal Circuits; the District of Massachusetts; the Northern and Southern Districts of West Virginia; and the Eastern and Western Districts of Virginia.
Director of Law & Policy, Environmental Integrity Project
Following Princeton and the University of Chicago Law School, David began practicing law at Paul, Weiss, Rifkind, Wharton & Garrison. Eventually tiring of litigation where the result was a wire transfer from Entity A to Entity B, in the early 1990’s David began his environmental law career at the Massachusetts Attorney General’s Office. Since then, he has litigated dozens of cases under all of the major environmental statutes including, as Sierra Club’s Chief Climate Counsel, initiating and managing Massachusetts v. EPA. Most recently, he has been busy challenging FERC’s permitting of natural gas pipelines and LNG export terminals. Apart from litigation, David has helped lead efforts on both greenhouse gas regulation and global warming legislation (and may be the only person ever invited to testify by both Barbara Boxer and James Inhofe).
He has drafted a range of federal climate legislation, advised states as to their greenhouse gas regulatory authority (and for many years has represented environmental groups defending state GHG regulations from dormant Commerce Clause challenges). David has designed and taught courses on “Environmental Litigation” at Georgetown University Law Center and “Environmental Law and Science” at the William and Mary Law School/Virginia Institute of Marine Science.
Director, Climate & Clean Air Program, Natural Resources Defense Council
David Doniger has been at the forefront of the battle against air pollution and global climate change since he joined NRDC in 1978. He helped formulate the Montreal Protocol, an international agreement designed to stop the depletion of the earth's ozone layer, as well as several essential amendments to the Clean Air Act. In 1993, he left NRDC to serve on the White House Council on Environmental Quality, followed by key posts at the U.S. Environmental Protection Agency. He rejoined NRDC in 2001 and has since been working to defend the Clean Air Act from assaults in Congress. He is based in Washington, D.C.
Former Administrator, U.S. Environmental Protection Agency
Scott Pruitt served as the 14th Administrator of the U.S. Environmental Protection Agency.
As Administrator, Mr. Pruitt’s overarching goal was to lead EPA in a way that our future generations inherit a better and healthier environment as he works with the thousands of dedicated public servants at EPA who have devoted their careers to helping realize this shared vision, while faithfully administering environmental laws.
Prior to the EPA, Pruitt served as the Attorney General for Oklahoma. Almost immediately upon taking office, he worked with his Democratic counterpart in Arkansas to reach agreement to study the water quality of the Illinois River, which crosses the border between the two states and has been enjoyed by generations of Oklahomans. The Statement of Joint Principles provides for a best science study using EPA-approved methods, with both states agreeing, for the first time, to be bound by the outcome.
Also during his tenure as Oklahoma’s Attorney General, Pruitt led an historic water rights settlement between Oklahoma, Oklahoma City and the Choctaw and Chickasaw Tribal Nations that preserved the ecosystems of scenic lakes and rivers on native lands. The agreement, which required Congressional approval, was enacted into Section 3608 of Public Law 114-322 and signed in December 2016. It provides a framework that fosters intergovernmental collaboration on significant water resource concerns with the settlement area, while at the same time protecting existing water rights and affirming the state’s role in water rights permitting and administration.
Water settlement cases can be lengthy, costly, divisive and disruptive; however under Pruitt’s forward-thinking leadership, the process was hailed by all parties as one of commitment, hard work, perseverance and cooperation.
Pruitt became a national leader through a career of advocating to keep power in the hands of hard-working Americans. He has a proven track record of working with others – including industry, farmers, ranchers, landowners and small business owners - who want to do the right thing by the environment.
He has dedicated his career to creating policy that serves the people. He strongly believes that environmental law, policy and progress are all based on cooperation between the states, cooperation between the states and EPA, and cooperation between regulators and the public. As Attorney General for Oklahoma, he led the state’s legal challenges against property rights intrusion, while protecting Oklahoma’s natural resources and environment.
He is recognized as a national leader in the cause to restore the proper balance between the states and federal government, and he established Oklahoma’s first federalism unit to combat unwarranted regulation and overreach by the federal government.
Before being elected attorney general, he served eight years in the Oklahoma State Senate where he was a leading voice for fiscal responsibility.
After earning his Bachelor’s Degree from Georgetown College and graduating from the University of Tulsa College of Law, Pruitt went into private legal practice, specializing in constitutional law.
In addition to his life as a civil servant, Pruitt is a successful entrepreneur. As a co-owner and managing general partner of Oklahoma City’s Triple-A minor league baseball affiliate, the Oklahoma City Redhawks, Mr. Pruitt took over the team’s marketing operations and helped the team become one of the minor league leaders in attendance and merchandise sales.
Pruitt is, first and foremost, a family man. He and Marlyn, his wife of 27 years, proudly raised their daughter, McKenna, and son, Cade, in Tulsa. Pruitt has made it a priority to pass on to his children the same principled family values with which he was raised.

In 2017, he was appointed to serve on the Administrative Conference of the United States. He also serves on the leadership council for the American Bar Association’s Administrative Law and Regulatory Practice Section, which he will chair in 2023–24. Before joining AEI, he was a research fellow at Stanford University’s Hoover Institution and an adjunct fellow at the Manhattan Institute.
Mr. White has a JD from Harvard Law School and a bachelor of business administration from the College of Business at the University of Iowa.
Senior Attorney, Pacific Legal Foundation
Chris Kieser practices in PLF’s property rights and equality before the law practice groups.
His property rights clients include Cedar Point Nursery, which challenged a California regulation requiring them to allow union organizers to invade their private property, as well as Randall and Kimberley Pavlock, who are fighting back against Indiana’s beachfront land grab along Lake Michigan.
Under equality before the law, Chris represents coalitions of Asian-American parents challenging discriminatory admissions policies for selective K-12 schools in New York City; Montgomery County, Maryland; and Fairfax County, Virginia. He also represents a parent organization in Connecticut challenging a racial quota that prevents many Black and Hispanic students from enrolling at the state’s magnet schools.
Chris has published law review articles in the William & Mary Environmental Law Review and the Federalist Society Review. His op-eds have appeared in the New York Daily News, National Review, The Blaze, the Daily Journal, and SCOTUSblog.
Chris clerked for the Honorable Daniel A. Manion of the United States Court of Appeals for the Seventh Circuit and the Honorable Thomas D. Schroeder of the United States District Court for the Middle District of North Carolina. He holds a B.A., cum laude, from the University of Notre Dame, and graduated magna cum laude from Notre Dame Law School in 2013. At Notre Dame, he was an articles editor of the Notre Dame Law Review.
Growing up on Long Island, Chris developed a deep passion for limited government and individual liberty, arguing with his more numerous progressive classmates. This experience made him deeply skeptical that government tinkering at the expense of individual rights ever works, whether it be denying a property owner the use of his land or a student a seat at her desired school because of her race. He chose PLF because it is the national leader in litigation that furthers individual liberty.
When he’s not working, you’re likely to find Chris rooting for the Mets and Fighting Irish or debating some arcane point of law (because apparently that doesn’t happen enough at work).
Chris is currently licensed to practice in California and admitted to practice before the Supreme Court of the United States, the United States Courts of Appeal for the Second, Seventh, and Ninth Circuits, and the U.S. District Courts for the Eastern and Central Districts of California, the Northern District of Indiana, and the Northern District of Illinois.
Chair, Issues & Appeals, Hunton Andrews Kurth LLP
The former Solicitor General of West Virginia, Mr. Lin has been on the front lines of many precedent-setting cases in appellate courts across the country, including in a US Supreme Court victory that George Will called “the court’s most severe rebuke of a president” since the Truman administration. Having argued more than 60 appeals, he brings to clients a well-honed ability to identify the most persuasive issues for appeal and a practiced understanding of how best to frame complex legal questions in appellate courts.
With experience in the private sector and multiple branches of government, Mr. Lin’s practice has spanned a wide range of issues, including major questions of constitutional and administrative law at the federal and state levels. On behalf of more than two dozen states, he won a stay from the US Supreme Court of the EPA’s Clean Power Plan. Described by the New York Times as an “unprecedented” order, the stay was the first time the Supreme Court had ever put a regulation on hold before review by a federal appeals court. In that same case, Elbert argued before the en banc DC Circuit in an historic proceeding that one commenter quoted in E&E News compared to “the NBA All-Star Game.” At the state level, Elbert led the effort that persuaded the West Virginia Supreme Court of Appeals to overturn an injunction of the state’s right-to-work law.
In 2013, Mr. Lin was appointed the Solicitor General of West Virginia. During his four-and-a-half year tenure, he served as a member of the Attorney General’s senior management team, oversaw all civil and criminal appeals, and argued nearly two dozen cases in federal and state appellate courts. He authored more than twenty-five briefs in the US Supreme Court and more than forty-five formal Opinions of the Attorney General.
Earlier in his career, Mr. Lin served as a trial attorney in the Federal Programs Branch of the US Department of Justice’s Civil Division, where he received a Special Service Award. He has also been a law clerk at all three levels of the federal judiciary: for Justice Clarence Thomas on the US Supreme Court; for Judge William H. Pryor Jr. on the US Court of Appeals for the Eleventh Circuit; and for Senior Judge Robert E. Keeton on the US District Court for the District of Massachusetts.
Mr. Lin speaks regularly on a wide variety of topics, including constitutional law, administrative law, environmental law, state and federal relations, the US Supreme Court, and appellate practice. He has testified before Congress, and has spoken at the national conventions of the American Bar Association, the Association of Corporate Counsel, the National Asian Pacific American Bar Association, the Federalist Society, Americans for Prosperity, and the American Legislative Exchange Council. He is an elected member of the American Law Institute, a public member of the Administrative Conference of the United States, and a fellow of the American Academy of Appellate Lawyers.
Mr. Lin is admitted to practice in the following federal courts: the Supreme Court of the United States; the First, Second, Third, Fourth, Fifth, Sixth, Seventh, Eighth, Ninth, Eleventh, D.C., and Federal Circuits; the District of Massachusetts; the Northern and Southern Districts of West Virginia; and the Eastern and Western Districts of Virginia.
