It was supposed to be the ultimate diplomatic triumph to seal her status in Athens.

Instead, Kimberly Guilfoyle has been dealt a bruising snub by President Trump, who on Wednesday flew straight back to Washington after wrapping up the NATO summit in Turkey – dodging a potential stopover in neighboring Greece, where the ex-fiancée of Donald Trump Jr is America’s ambassador.

Trump Sr has no public events scheduled Friday through Sunday, putting to bed any notion there wasn’t time to make a quick stop.  

The Daily Mail reported in February that State Department officials had drawn up a potential plan for Trump to visit Athens either before or after the NATO summit in Ankara, though nothing had been confirmed.

Trump’s decision not to take the hour-long flight has left his first female Ambassador to the Hellenic Republic facing embarrassment – and not least because she had promised the Greeks a presidential visit.

In May, the 57-year-old former Fox News host had trilled to a local network that while she couldn’t reveal ‘the exact date… he is going to come to Greece.’

At the time, the White House rather awkwardly said that no such trip was yet on the calendar. As one Greek insider put it: ‘Kimberly has confused her personal vision board with the official White House schedule.’

Now, diplomatic insiders tell the Daily Mail that the Greeks are ‘disappointed’ and ‘jaded.’

‘Her selling of access is just not bought anymore,’ one source said.

Trump’s snub comes amid growing concerns in Athens that Guilfoyle’s influence over US foreign policy has fallen drastically short of what appeared to have been promised.

There are also fears, say insiders, that Tom Barrack, the high-flying US Ambassador to neighboring Turkey, has fostered significantly more sway in the Trump administration, despite Guilfoyle’s former family ties to the president.

Guilfoyle was engaged to Trump’s eldest son, who is nine years her junior, from 2020 to 2024. Almost immediately after their split, the president nominated Guilfoyle for the ambassador posting. The role comes with a grace-and-favor villa, Jefferson House, near to the Acropolis.

In February, Guilfoyle visited Washington, DC, and personally urged Trump to commit to a high-profile visit to Greece in a bid to help restore her image – which never really got off the ground.

It certainly didn’t help that, back in 2015, Guilfoyle had dismissed the Greek people live on Fox News as ‘freeloaders’ and accused them of ‘retiring too early’.

‘It doesn’t matter if you made great yogurt. I don’t care,’ she quipped.

Soon after Trump picked her for the role, sources warned that the ‘Margarita Girl’ – as one former Fox colleague dubbed her because of her apparent love of the cocktail – to be on her best behavior and that the gig was not simply for partying in the sunshine.

Guilfoyle appears to have taken the criticism in her stride, and just this month was pictured at gay-friendly Nammos beach club on Mykonos enjoying a glass of Champagne with the US Ambassador to Belgium, Bill White, and his husband. The following day, she flew into Paris and wore a nearly-nude maxi dress adorned with hundreds of crystals to attend the fashion week show of Greek designer Celia Kritharioti.

But while she has successfully persuaded lower ranking Trump officials to visit her – including Secretaries of the Interior and Energy, Doug Burgum and Chris Wright – it was a visit from the big man himself that she desperately coveted.

And with the NATO summit scheduled for July 7 to 8 in neighboring Turkey, an Athens stopover for Trump seemed like a logistical no-brainer.

‘She is better than [Tom] Barrack at photo-op diplomacy, but he is racking up policy wins. Over the last 10 years, Greeks thought they had an advantage when it came to the US ambassador in Athens compared to the US ambassador to Turkey, and now they feel like they don’t,’ a source familiar with the inner workings of the Greek embassy said.

Still, Guilfoyle’s supporters say she shouldn’t be counted out. ‘Her greatest accomplishment has been getting high-level eyes on Greece so far,’ one source said.

But there’s no escaping the fact the Trump administration seems to be moving forward with a controversial arms sale worth $700million with Turkey, despite deep apprehension over Ankara’s closeness to Russia and terrorist groups in the Middle East.

On Wednesday, Trump suggested he was rewarding Turkish President Erdogan for keeping out of Israel’s war with Iran. ‘He could have gone into that war very easily, and he did not,’ Trump told reporters.

The sale would allow Turkey to once again acquire US-made stealth fighter jets. In 2019, Turkey was banned from the F-35 fighter jet program as part of sanctions for purchasing Russian defense missiles.

Guilfoyle’s supporters say she shouldn’t be counted out. ‘Her greatest accomplishment has been getting high-level eyes on Greece so far,’ one source said. 

Notably, during her confirmation hearing for the ambassador role last July, Guilfoyle fiercely defended the Turkey ban.

‘There are choices countries make. Turkey chose to work with the Russians. That’s why they’re out of the F-35 program,’ she said.

Just this month, Guilfoyle met with former Greek Prime Minister and leader of the newly formed Greek Left Alliance, Alexis Tsipras, who urged the Trump administration to halt the sale of additional US military equipment to Turkey, including F-35 jets.

Greece was never Guilfoyle’s first choice.

The former Fox News host had lobbied hard to become US ambassador to the Holy See, multiple sources told the Daily Mail. But Trump shut the idea down almost immediately. The prestigious Vatican role was ‘a non-starter’, said one source.

So Greece was the compromise, and a face-saving one at that.

As Guilfoyle headed off to the Mediterranean, Don Jr settled down with Palm Beach socialite Bettina Anderson, 39, who he married in May this year.

A spokesperson for the Embassy in Athens told the Daily Mail: ‘Ambassador Guilfoyle has said many times that she hopes President Trump will visit Greece in the future when his schedule permits. It has never been tied to a specific event.’

A spokesperson for the White House said: ‘The President went to Turkey for NATO and there were never plans or expectations that he would go anywhere else afterward. Ambassador Guilfoyle has done an incredible job in her role to advance the President’s America First agenda abroad.’
