Taking dual aim at the plaintiffs bar and a coalition of state prosecutors, Exxon Mobil Corp. has filed an unusual lawsuit against the lawyers who subpoenaed documents from the company related to climate change.

On Wednesday, Exxon and its attorneys at Paul, Weiss, Rifkind, Wharton & Garrison and Haynes and Boone sued plaintiffs lawyer Linda Singer and her firm Cohen Milstein Sellers & Toll after they sent a subpoena on behalf of the attorney general of the U.S. Virgin Islands. The suit also targets Claude Walker, the U.S. Virgin Islands’ attorney general.
