The Department of the Taoiseach has denied a US media report that the Irish Government has spent money at Donald Trump's golf resort in Doonbeg, Co Clare.

According to NBC News, Ireland is one of at least nine countries that were involved in hosting events at Trump properties around the world.

During last week's visit to Ireland by President Trump, his Chief of Staff Mick Mulvaney hosted a dinner for Irish officials at Doonbeg.

It was attended by Irish Ambassador to the United States Dan Mulhall, the Government's special envoy to the US John Deasy, and Fianna Fáil Senator Mark Daly.

In a statement today, the Department of the Taoiseach said President Trump's recent visit to Ireland was essentially a private visit, except for his meeting with the Taoiseach, which Leo Varadkar hosted at Shannon Airport.

"The question of the Government hosting an event at the Trump International Hotel and Golf Links in Doonbeg simply did not arise," the department said.

"The Department of the Taoiseach can confirm that it has never hosted an event at any Trump property."

The NBC News report claims that other foreign governments have rented or purchased Trump properties and that some have stayed at or attended events at venues linked to the US President.

NBC says the information is based on news accounts and other public records and that, in total, representatives of at least 22 foreign governments appear to have spent money at Trump Organisation properties.
