In “U.S. Antitrust Enforcement in the Trump Administration,” Daniel Bitton and Melanie Kiser look back on government antitrust enforcement during the Trump Administration in more detail and conclude with a brief forward look at what to expect under the Biden administration. The article offers practical insights on what companies and counsel can learn from recent enforcement actions and expect going forward in the new administration.
