Kimberly Guilfoyle’s departure as US ambassador to Greece has brought competing plans for American liquefied natural gas exports into the political debate in Athens, with Greek commentary questioning whether commercial rivalries contributed to her downfall.
Claims of Turkish involvement have also surfaced. However, there is no evidence, at least publicly, that Ankara influenced the coverage of Guilfoyle or Washington’s decision to seek her resignation.
The White House announced on October 13, 2026, that it had asked Guilfoyle to resign following reports alleging misconduct. She denied wrongdoing and said she intended to defend her reputation.
Her departure came less than a week after Secretary of State Marco Rubio visited Athens and emphasized Greece’s role in US energy plans for Europe. That timing has sharpened questions about the future of projects she promoted, particularly the Vertical Corridor.
Controversy to LNG competition
Voices in Greece suggest a Turkish connection to critical reporting about Guilfoyle, framing the controversy against competition to supply American LNG to European markets.
Reports highlighted competing American LNG interests in the region. US company Venture Global is working with Greece’s Atlantic-SEE LNG Trade to supply gas through the Vertical Corridor, while another American company, Argent LNG, has established commercial ties with Turkey. According to this reading of the events, business interests provided a possible explanation for the pressure surrounding the ambassador.
That remains unsubstantiated interpretation, as no Turkish authorities have directed the reporting or persuaded US officials to remove Guilfoyle, at least according to what we know so far. It also has to be noted that these is no existence of competing commercial interests currently in the region that could demonstrate that either side orchestrated her departure.
The distinction matters because Washington’s stated action followed misconduct allegations. A separate debate over energy contracts does not resolve those allegations, which Guilfoyle disputes.
Greece’s TV station OPEN also published recently an interview featuring Professor of Economic Geography and Geopolitical Theory Ioannis Mazis under a headline describing a fierce business conflict behind the resignation.
Why the Vertical Corridor matters to Greece
The energy stakes extend well beyond one diplomatic appointment. Greece has sought to strengthen its position as a gateway for natural gas moving north into Southeastern and Central/Eastern Europe, including Ukraine.
The Vertical Corridor framework, backed by the United States and participating European governments, aims to increase the use of pipeline routes carrying gas from Greece through Bulgaria, Romania and Moldova toward Ukraine. American LNG delivered to Greek import terminals forms part of that strategy.
Washington’s support predates the current controversy around the former US ambassador to Greece. US officials praised Greece’s participation in the corridor earlier this year, while subsequent discussions addressed the practical barriers to expanding northbound gas flows.
Those barriers include transport tariffs, regulatory coordination and infrastructure investment. The corridor’s commercial prospects depend on whether suppliers can deliver gas at prices customers will accept, as well as on political support.
Athens has also presented energy diversification as a security priority. During energy discussions in Washington in February, Greek Environment and Energy Minister Stavros Papastavrou warned against Russian gas reentering European markets through alternative routes.
The question now is whether policy changes
For Greece, the immediate issue is whether Guilfoyle’s departure affects Washington’s backing for the corridor or the implementation of commercial agreements associated with it.
There is still no credible evidence to establish that her exit has changed US policy or canceled any agreement. Rubio’s recent support for energy cooperation provides a relevant statement of Washington’s position before the resignation request, but does not settle how individual projects will proceed.
Any claim that an energy rivalry caused Guilfoyle’s removal would require evidence connecting the businesses or governments concerned to the decision in Washington. The commercial competition explains why the controversy has attracted attention in Greece. It does not, by itself, establish who brought down the ambassador.
