Mr Trump was expected to visit his golf course in Doonbeg, County Clare, and Dublin on the weekend of 10-11 November.
President Trump has canceled a planned trip to Ireland, the Irish government said Tuesday, amid planned demonstrations to protest his climate policies, worldwide relations and treatment of immigrants, women and minorities.
"We hadn't known until just a couple of days ago that he was going to take the opportunity of his visit to Paris for the Armistice commemorations, commemorating a hundred years of the end of the First World War, to visit Dublin, and also he's going to go to Doonbeg too".
Meanwhile, Russian media reported Tuesday that Trump may meet with Russian President Vladimir Putin during the same European trip that had included the planned Ireland visit.
In 2017, Mr Varadkar's predecessor, Enda Kenny, also extended an offer for the U.S. president to come and visit.
Confusing matters, White House press secretary Sarah Sanders claimed in a statement shortly afterward that the administration was still "finalizing" whether Ireland will be a stop on a previously announced trip to Europe.
Earlier today, before the news that Trump's visit is set to be cancelled, Fianna Fáil leader Micheal Martin told politicians in his party would be allowed to protest if they wished and that he "no difficulty" with members of the party setting out their opposition to his policies. "This is all; the meeting is under consideration as there is still time left", he said.
The Irish Government had been heavily criticised for the planned visit.
Mr Varadkar said there is a standing invitation for any United States president to come to Ireland and many have in the past.
Asked if he had ever seen such haphazard organisations for a visit by a US President Mr Martin, a former foreign affairs minister said: "No I haven't I have never seen anything like this before".
He said: "Those are the issues I think we need to reset the button on".
