Former special counsel Jack Smith is starting his own law firm with three former prosecutors who have investigated President Donald Trump and the Jan. 6 attack on the U.S. Capitol. They include Timothy Heaphy, a Willkie Farr & Gallagher partner who served as chief investigative counsel for the House Select Committee on the Jan. 6 attack. Heaphy confirmed news of the new venture late Tuesday to the National Law Journal. Also joining the firm as partners are Thomas Windom, a veteran federal prosecutor who worked with Smith on the Trump election interference case, and David Harbach, who also worked on the election interference case. The new firm will focus on trial and investigations work, Heaphy confirmed, declining to provide further details until the firm launches in January. Heaphy joined Willkie in 2023 after his time with the Jan. 6 House Select Committee. He has cochaired the firm’s investigations & enforcement practice. His departure comes after Willkie reached a pro bono deal with the Trump administration on April 1, when the firm promised $100 million in pro bono legal services to causes President Trump supports. A Willkie spokesperson wished Heaphy well. Smith was appointed in 2022 to oversee the Justice Department investigations into Trump’s efforts to overturn the 2020 election and classified documents found at his Mar-a-Lago home. Smith is in the middle of a congressional inquiry himself now. Republican lawmakers have been probing Smith’s time as special counsel, arguing that the Biden administration had weaponized the Justice Department. Smith is expected to appear next week at the Capitol for a private testimony with the House Judiciary Committee. Windom has also come under attack this year from Republican lawmakers. House Judiciary Chairman Jim Jordan (R-OH) referred Windom to the Justice Department for criminal prosecution after Windom declined to answer questions during a deposition with the committee. The new firm by Smith and others will join a cadre of other newly launched boutiques, including one started by two of Smith’s top deputies on the election interference case. Molly Gaston and J.P. Cooney, who worked on Smith’s team investigating Trump’s efforts to overturn the 2020 election, launched Gaston & Cooney, a D.C.-based boutique focused on providing anti-corruption counseling to local and state governments, as well as congressional investigations and white-collar defense services. Nearly a dozen law firms have launched since the start of this year, including Dunn Isaacson Rhee, Lowell & Associates, DC Law Collective, Klubes Law Group, Washington Litigation Group and Civil Service Law Center, among others, which are already or aiming to take up high-stakes disputes work opposite the Trump administration.
