Investigations and Litigation practice who focuses his practice on civil antitrust litigation and investigations.  He provides strategic guidance to clients on all issues that relate to antitrust, and represents companies in court and before the agencies in their most important matters.

He represents clients in all aspects of government investigations and private antitrust litigation, and has guided clients through complex merger and civil investigations involving some of their most significant issues. John also has handled high-profile trials and litigation in both private practice and during his tenure with the FTC, and represents clients in high stakes class action litigation.

Both Chambers USA and Legal 500 have recognized John as a leading antitrust lawyer. Chambers reports that "[c]lients find him to be an 'endless resource' who does 'excellent work' across the board." He has also been listed in Benchmark Litigation as a “Litigation Star” and in Washington, D.C.
