Donald Trump's visit to Ireland this autumn has been "postponed" due to scheduling reasons, according to the Irish Government.
Mr Trump was originally invited to Ireland by former taoiseach Enda Kenny on his final St Patrick's Day visit to the White House previous year.
The brief trip to Ireland was scheduled to take place as he made his way home from Armistice Day commemorations in France on November 11.
The visit to Ireland, announced by the White House in early September, was scheduled to be combined with Trump's trip to Paris to commemorate the 100th anniversary of the ending of World War I.
"There is an open invitation to the US President to visit Ireland at any time, I think they've all visited since Reagan, if not before and obviously there's an open invitation for me, or any future Taoiseach, to attend Washington in March".
"Help us to do so if you abhor his policies on climate change, refugee migration, trade wars, military expansion, economic inequality and the whole gung-ho, misogynistic, racially divisive show".
There were plans for Trump to spend one day in the capital before travelling to Doonbeg in County Clare where he owns a golf course.
Scientists say those threats are the outcome of something for which Trump has firmly rejected government planning: climate change.
The Irish Government had been heavily criticised for the planned visit.
In 2017, Mr Varadkar's predecessor, Enda Kenny, also extended an offer for the United States president to come and visit.
Brendan Howlin, the leader of the Labour Party in the Republic of Ireland, said that Mr Trump was "no friend of democracy or human rights".
That summit, in Helsinki, led to widespread criticism that Trump was deferential to Putin and did not challenge him about Russian interference in the 2016 US presidential election.
