Antitrust enforcement may be becoming an increasingly politicized issue, however, most policies are fairly consistent from administration to administration and, consequently, from one Attorney General to the next. Replacing Attorney General Matthew Whitaker, William P. Barr was recently appointed by the Senate to serve as Attorney General. Having previously served as Attorney General under President George H.W. Bush, and given that during his tenure, the Department of Justice (DOJ) implemented several important antitrust policy initiatives, there are a few particular areas of enforcement in which there are opportunities for Barr to guide antitrust policy. Given his prior stint as Attorney General and his professional experiences since, we outline below the potential impact on antitrust enforcement and policies that Barr may introduce as Attorney General. Members of our antitrust team explain what that means for antitrust practice in our client alert.
