Jack Smith, the former U.S. Justice Department special counsel known for prosecuting cases against former President Donald Trump, is set to establish a new law firm in January. Joining him are Tim Heaphy, David Harbach, and Thomas Windom, all seasoned federal prosecutors with extensive public service backgrounds.

The firm aims to offer comprehensive legal services, focusing on investigations and litigation. Heaphy emphasized their commitment to “integrity, commitment, and zealous advocacy” for both public and private clients.

All four attorneys have been involved in high-profile investigations related to Trump. Smith, Harbach, and Windom secured indictments against Trump concerning efforts to overturn the 2020 election and the mishandling of classified documents. Heaphy served as the chief investigative counsel for the House committee investigating the January 6, 2021, Capitol attack.

Heaphy is departing from Willkie Farr & Gallagher LLP to join this new venture. Earlier this year, Willkie reached an agreement with the Trump administration to provide $100 million in pro bono legal services, a move that led to internal dissent and the departure of several partners.

This development reflects a broader trend of legal professionals who have been involved in investigations against Trump forming independent practices. The new firm is expected to leverage the extensive experience of its founders in handling complex, high-stakes legal matters.
