Mark Green Sued Over Prosimos Dealings In Guyana Former Congressman Mark Green is facing a civil lawsuit alleging he used confidential business information from one energy venture to secure a competing deal in Guyana. Court documents filed this week accuse Green, lobbyist Marc C. Hebert, and law firm Jones Walker LLP of leveraging insider knowledge to pursue a fuel exchange agreement in the South American nation. The plaintiffs, Curlew Midstream LLC and Playera Group Global LLC, claim Green and Hebert accessed Playera’s proprietary data and later used it to benefit their own interests through a company they co-founded after Green left Congress. The lawsuit details how Green and Hebert formed a Florida-based entity called Prosimos following an April meeting with the plaintiffs. According to the Nashville Banner, the suit alleges they immediately began negotiating the Guyana fuel deal using Playera’s confidential information. Florida business records confirm that PROSIMOS LLC was registered on June 23, 2025, with Hebert listed as the registered agent and Green as an authorized member. The company’s Miami principal address and New Orleans mailing address for Hebert are noted in the Florida Division of Corporations records. The complaint states that Curlew and Playera initially negotiated a fuel exchange arrangement directly with Guyanese officials. However, the deal shifted in mid-January when an unnamed consultant was introduced into the process. The plaintiffs allege Green traveled to Guyana around that time and, shortly afterward, used Playera’s confidential data to undercut or duplicate the opportunity through Prosimos.#mark_green #marc_c_hebert #jones_walker_llp #curlew_midstream_llc #playera_group_global_llc
