Law firm leaders on Wednesday were still studying the impact of the 2018 election results on their business, but noted some practices, such as government relations and New York real estate, may see a significant change in business and practices.

Still, for law firms, much of the impact going forward is unclear, especially with the election being followed Wednesday by the sudden resignation of Attorney General Jeff Sessions. While a few firms may benefit from representing targets or witnesses in potential House investigations on President Donald Trump, for example, that alone won’t represent a sea change in business for litigation firms.
