Axinn Veltrop & Harkrider‘s antitrust practice is centered in Washington DC, and is led by Michael Keeley, the firm’s Antitrust Practice Chair. The practice is noted for its strength in cartel and government investigations, underpinned by a group of partners with extensive DOJ experience. Tiffany Rider is a standout figure in high-stakes cartel defense and follow-on civil litigation, regularly leading matters involving parallel criminal investigations, treble-damages class actions, and complex settlement strategy. Partners James Attridge and Daniel Oakes are increasingly prominent, advising companies and executives in sensitive price-fixing, bid-rigging, labor-market, and algorithmic-pricing investigations, as well as related compliance and internal reviews. The team manages matters involving overlapping criminal, civil, and multijurisdictional exposure, including public procurement, technology, manufacturing, and real estate-driven investigations.
