Former White House press secretary Sean Spicer will be interviewed live on the Late Late Show this Friday.
Mr Spicer, who quit as President Donald Trump's press secretary in July, was invited by RTÉ to be a guest on the programme last year. He is doing no other television interviews in Europe.
A Late Late Show spokesman said “nothing will be off limits” in their discussions with the controversial former press secretary who has continued to defend Mr Trump since leaving office.
Host Ryan Tubridy said Mr Spicer had a "front row seat" in the Trump presidency.
Tubridy described the presidency as the “one of the most fascinating and extraordinary things to happen in our lifetime”.
He added: “I am really looking forward to getting his first-hand account of what it was like to be there in that White House with the world’s media watching and his insights into what’s really going on in Trumpland.”
Mr Spicer will talk about the media sensation surrounding the recent publication of the book Fire and Fury, which he claims contains inaccuracies.
He will also addresse some of the controversies during his short tenure as White House press secretary, most notoriously his claim - despite the evidence to the contrary - that the crowds attending Trump’s inauguration was the biggest ever seen at such inaugurations.
He is expected too to say what he thinks of Melissa McCarthy’s infamous impression of him on Saturday Night Live, and why he ultimately decided to resign.
Mr Spicer, who has previously visited Ireland several times, will also be seeking to find out more about his Irish roots. His great-grandfather William Spicer emigrated from Kinsale in the 19th century.
Mr Spicer is currently writing his own book about his tempestuous nine month spell as White House press secretary. Entitled The Briefing, it will be available in summer 2018.
Actor Liam Neeson will also be appearing on Friday's show.
