Through historic executive action and key appointments, President Joe Biden has signaled that his administration will push for an aggressive application of the antitrust laws. Big tech has already been placed on notice that the administration views it as an industry that needs change, and companies across many other industries will also likely be under the microscope when trying to get their mergers through, especially where there is significant market concentration.

Biden's most recent appointment of Jonathan Kanter to head the Department of Justice's (DOJ) Antitrust Division is consistent with his previous moves to ensure that the top antitrust enforcement positions are filled by those with an aggressive enforcement track record. The White House called Kanter "a leading advocate and expert in the effort to promote strong and meaningful antitrust enforcement and competition policy."
