U.S.President Donald Trump's decision not to visit Greece has embarrassed his ambassador, Kimberly Guilfoyle, who had promised to host him during his return trip from the NATO summit in Ankara.

Insiders reveal that Guilfoyle, Trump's ex-fiancée, had assured Greeks of his visit, but Trump's absence has left diplomats in Athens disappointed.The move questions her influence over U.S.foreign policy, with sources indicating her sway has waned.

Guilfoyle, known for past controversial remarks about Greeks, has managed to secure visits from lower-ranking officials but not the president himself.Despite her efforts to maintain relevance through social events, her clout appears to have diminished significantly.
