US President Donald Trump asked Taoiseach Leo Varadkar for further clarity on the Northern Ireland peace process.
During a phone call today, Trump requested a broader explanation on how the border works between Northern Ireland and the Republic of Ireland - something which he also asked of former Taoiseach Enda Kenny when he met him last St Patrick's Day.
He also congratulated Varadkar on his election, and said he looked forward to meeting him next St Patrick's Day.
However, a visit by Trump to Ireland was not brought up during this conversation, despite Kenny extending the invitation during his visit.
Other topics discussed included migration, Brexit, climate change, free trade, Irish inward investment in the US, and the undocumented Irish.
The Taoiseach also held a call with the UK Prime Minister, Theresa May, this afternoon in which they discussed the ongoing efforts to restore the Executive in Northern Ireland ahead of Thursday's deadline, and the supply and confidence agreement between the Conservative Party and the DUP.
There was speculation as to why Trump was kept on hold for a minute and a half before speaking with Varadkar. However, it was revealed that this was to allow time for Varadkar to finish answering questions in the Dáil.
Since his confirmation as Taoiseach he has spoken to the French President Emmanuel Macron, the German Chancellor Angela Merkel and the Indian Prime Minister Narendra Modi.
