President Trump has phoned to congratulate Ireland’s new Taoiseach (Prime Minister) Leo Varadkar.

Trump made the call from the Oval Office, surrounded by journalists, photographers and White House staff.

"Congratulations on your great victory. We have so many people from Ireland in this country – I know so many of them, I feel I know all of them,” he told the new Taoiseach.

“But I just wanted to congratulate you, that was a great victory that you had".

The President also told Varadkar that, ”We have all this beautiful Irish press” and summoned over to the Resolute Desk RTÉ’s Washington Correspondent, Caitriona Perry. “She has a nice smile on her face,” he added. “So I bet she treats you well.”

In total, the call lasted between 10 and 15 minutes, after which the White House described the talks as “wide-ranging” and “fruitful”.

It’s understood that Trump reissued the long-standing invitation for the Taoiseach to visit the White House on St Patrick’s Day and the pair discussed the issue of the undocumented in America, climate change, and trade.

Trump also asked what Britain’s ongoing withdrawal from the European Union would mean for the Northern Irish peace process and the Irish border.

Trump’s first calls to world leaders have been known to cause diplomatic incidences; after his election, he accepted a phone call from the President of Taiwan - something that sparked outrage in Beijing, which refuses to recognize the country’s sovereignty.

His call to Australian Prime Minister Malcolm Turnbull in January ended abruptly after he reportedly told Turnbull he’d phoned numerous other world leaders that day but that, “this was the worst call by far.”

He later said that reports that the call had ended badly were “a little bit of fake news."
