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
Refined Fuels Deal at Center of US Lawsuit A legal dispute involving a refined fuels agreement between the Guyana government and a US company has escalated into a lawsuit in an American court. The case centers on allegations that confidential trade information was misused to gain an advantage in securing the deal. The lawsuit, filed in Florida in late February, names former Tennessee congressman Mark Green, lobbyist and attorney Marc C. Hebert, and Hebert’s law firm Jones Walker LLP as defendants. The suit was brought by Curlew Mainstream LLC and Playera Group Global LLC, which claim the defendants improperly used protected business information to pursue a refined fuels contract with Guyana. The report by the Nashville Banner states that Green, who served as a congressman during the time the alleged misconduct occurred, traveled to Guyana multiple times. Hebert, who previously represented Playera as it collaborated with Curlew to secure the fuel supply arrangement, is accused of leveraging confidential details from that relationship to establish a competing venture with Green. Last year, Green and Hebert formed Prosimos, a company the lawsuit alleges was created to compete for a similar fuel agreement in Guyana. The filing claims that during a meeting in Washington, D.C., in April 2025, Green and Hebert suggested they could influence whether Curlew Midstream secured a proposed fuel exchange agreement. At the time, Green was chairman of the US House Homeland Security Committee. The same week, Prosimos was established in Florida, and the defendants allegedly communicated with the Guyanese government about issues with Curlew’s pending agreement, actions the plaintiffs say delayed the deal.#mark_green #marc_c_hebert #guyana #curlew_midstream #playera_group_global
Mark Green faces lawsuit over Prosimos dealings in Guyana Before Mark Green abruptly retired from the U.S. House of Representatives last summer, the embattled congressman and his lobbyist business partner allegedly used trade information from one of the partner’s clients to compete for a lucrative fuel agreement with the Guyanese government. Last spring, Green established a company called Prosimos alongside lobbyist and corporate attorney Marc C. Hebert. In June, Green announced his retirement from Congress, less than six months into his fourth term, which he won in a 2024 campaign marked by personal drama involving his divorce, an alleged affair, and family tensions. In July, he stepped down, triggering a special election to replace him in a midstate district. While campaigning for his successor, Rep. Matt Van Epps, Green told the Nashville Banner that Prosimos was designed to compete with Chinese companies for international business, stating, “The motto is basically, ‘If an American company doesn’t do it, a Chinese company will.’” At a September event for Van Epps, Green emphasized his commitment to supporting American companies abroad, saying, “You don’t serve the country for 36 years in some capacity and [not] still want to do some good.” At the center of Prosimos’ operations is Guyana, a South American nation that Green visited repeatedly during his final months in office, including during his retirement announcement. Since discovering a large oil reserve off its coast in 2015, Guyana has become a target for foreign investors seeking to profit from its resources and infrastructure needs. However, the lawsuit claims this was not the original plan for Prosimos.#mark_green #marc_c_hebert #jones_walker_llp #guyana #curlew_mainstream_llc
