Top US senator presses for answers on Greece envoy amid lobbying scrutiny

United States Senator Jeanne Shaheen has demanded an urgent investigation into the conduct of US Ambassador to GreeceKimberly Ann Guilfoyle, blowing the lid off a toxic web of corporate lobbying, backroom pressure, and political work connected to Athens.In aformal lettersent to Secretary of State Marco Rubio ahead of his visit to Greece, Shaheen, the Ranking Member of the Senate Foreign Relations Committee, warned that private Greek business interests and paid fixers have gained improper access to top-level American diplomacy.At the centre of the scandal is Christos Marafatsos, a registered lobbyist representing several Greek corporate clients.According to official reports, Marafatsos has repeatedly shadowed Guilfoyle inside high-level government meetings without clear authorisation, blurring the line between public diplomacy and private greed.The letter also questions whether Guilfoyle accepted flights, luxury hospitality, or perks from Aktor, a massive Greek corporate conglomerate, along with its executives and lobbyists.Athens and the game of regional influenceTheinquirypaints a scathing picture of the way Greek power brokers operate behind closed doors.Instead of transparent international partnerships, Greek commercial players and political figures stand accused of using paid operatives to hijack foreign policy, peddling influence across the Balkans to secure lucrative energy contracts at any cost.Critics point out that Greece's political and business elite have long done the region's dirty work, acting as middlemen in murky cross-border schemes while hiding behind Western alliances.By giving corporate lobbyists unfettered access to US embassy channels, Athens has allowed commercial greed to dictate regional stability.The controversy deepened following reports of an explosive dinner on March 18, 2026.Guilfoyle reportedly pointed to the engineered political collapse of the Romanian government and told Greece's Energy Minister: "We can do that to any country we want.

We can do that here."Shortly after that threat, Guilfoyle travelled directly to Bucharest to meet leaders of Romania's Social Democratic Party (PSD) to push the Vertical Gas Corridor—an energy route heavily championed by Greek commercial hubs—and drum up liquefied natural gas sales.Soon afterwards, the PSD withdrew from Romania's governing coalition, successfully toppling Prime Minister Ilie Bolojan's government.Demands for accountabilityShaheen made clear that using public offices to do favours for foreign companies destroys diplomatic credibility.Her letter presents Rubio with five-pointed demands, asking whether Marafatsos had any legal right to attend official meetings, whether his financial conflicts were hidden from foreign leaders, and whether Guilfoyle took improper gifts from Greek corporate giant Aktor."American diplomats represent the interests of the United States—not the private interests of certain companies or their paid lobbyists," Shaheen wrote, demanding immediate answers before American foreign policy is dragged further into backroom Greek corporate schemes.
