Senior Attorney, Pacific Legal Foundation
Oliver Dunford joined the Pacific Legal Foundation in March 2017. He litigates across the country to defend and advance individual liberty and the rule of law. Oliver’s cases involve the separation of powers, economic liberty, property rights, and the First Amendment.
Oliver remains inspired by the Classical Liberal ideals upon which our Founders declared independence and secured the blessings of liberty. The Constitution’s promises, however, are not self-executing. As James Madison explained, “In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself.” Oliver feels lucky that his work helps oblige the government to control itself—to the end that all individuals may pursue their rights of life, liberty, and the pursuit of happiness.
Before joining PLF, Oliver clerked at the Ohio Supreme Court and the Ohio Court of Appeals, and spent more than a decade in private practice working on complex commercial litigation. Originally from Cleveland, Oliver is a graduate of the University of Dayton and Cleveland-Marshall College of Law, where he was a managing editor for the Cleveland State Law Review. Oliver is admitted to the state bars of Florida, California, and Ohio, as well as several federal courts including the United States Supreme Court.
Oliver spends all of his free time following the Cleveland Indians.
Partner, Phelps Dunbar LLP
Mike Hurst is a partner with Phelps Dunbar LLP where he optimizes his in-depth knowledge of the court system, investigative and prosecutorial agencies, the regulatory arena, and the public policy realm to help clients facing government investigations, enforcement actions, regulatory matters, general litigation and policy issues. Mike currently serves as the General Counsel of the Republican National Committee and as Chairman of the Mississippi Republican Party. He previously served as the U.S. Attorney for the Southern District of Mississippi from 2017-2021, and with over 20 years of experience before judges, juries and policy makers, handling some of the largest and most high-profile cases in Mississippi, he's known for untangling the most complex legal issues.
As U.S. Attorney, Mike was described as a “hard charger,” leading efforts to combat violent crime, human trafficking and public corruption, among many other issues, throughout Mississippi. He almost tripled prosecutions in the U.S. Attorney’s Office over a three-year period, resulting in the most indictments and federal defendants indicted in a one-year period in Mississippi history. He created innovative and national award-winning crime-fighting solutions, like “Project EJECT,” and he established the first statewide, multilevel and multidisciplinary human trafficking body, the Mississippi Human Trafficking Council, to comprehensively and holistically address this criminal scourge.
During his tenure as U.S. Attorney, Mike oversaw some of the biggest cases in Mississippi history: the largest health care fraud scheme (Wade Walters, et. al.), the largest Ponzi scheme (Lamar Adams), the largest False Claims Act health care fraud settlement (Region 8), and the largest nursing home False Claim Act settlement (Hyperion). In addition, as Chief Federal Law Enforcement Officer for the Southern District, Mike coordinated the largest single-state immigration worksite enforcement operation in our nation’s history, involving hundreds of federal law enforcement agents covering seven different locations operated by multiple companies.
Mike’s no show pony – he’s a work horse. Before his tenure as U.S. Attorney, Mike was an Assistant U.S. Attorney for the Southern District of Mississippi for more than eight years. He handled some of the most difficult and complex cases in that office, dealing with white collar crimes, public corruption and financial fraud, including numerous jury trials before almost every federal judge in the Southern District.
He also has experience in the private sector. He has practiced law in Washington, D.C., and has served as a litigator and general counsel for a conservative nonprofit. He also has extensive experience in public policy, having served as the Legislative Director to a U.S. Congressman and as Counsel to the House Judiciary Committee.
Mike has also testified before both the United States Senate and the U.S. House of Representatives on issues ranging from crime to Presidential pardons. He has worked on all sides of the legal, regulatory, investigative, prosecutorial and policy spectrum. The incredible insight gained from this varied experience enables him to find a path forward for clients, no matter how complicated the case.
