US President Donald Trump has landed in Ireland amid a visit to Dublin and to Clare.

The President of the United States landed in Dublin Airport shortly after 8am on Saturday morning (September 12), where he will meet with President of Ireland, Catherine Connolly, in Áras an Úachtaráin.

From there, Mr Trump will head to Co Clare, specifically his Doonbeg golf course, which is currently hosting the AmGen Irish Open.

Mr Trump travelled to Ireland in his new Air Force One, the Presidential jet that was donated to him by the Qatari royal family.

High-level security operations are in place in both Dublin and Shannon Airport, and rolling road closures are set to be in place in the capital ahead of Mr Trump’s visit to President Connolly.

Dublin Airport warned passengers travelling to and from the airport that, due to these road closures, they should allow for more time to travel to the airport so they don’t miss their flight.

‘Dublin Airport advises passengers travelling to the airport on Saturday morning and early afternoon to allow extra time for their journey due to possible rolling road closures in the vicinity of the airport,’ the daa wrote. ‘To facilitate the visit of the President of the United States, Donald Trump, rolling road closures will be in place from 0730–0930 and 1130–1330.’

‘Dublin Airport will operate as normal, but passengers may not be able to access the airport via their usual route and may need to take an alternative, potentially longer, route,’ they added. ‘Passengers are advised to use traffic apps and check the latest updates from @TIITraffic and @GardaTraffic before travelling.’

Shannon Airport has also put huge security measures in place ahead of Mr Trump’s visit, advising people travelling to the airport to have photo ID and their flight information ready while approaching the airport.

‘A reminder to passengers that from 08.00am tomorrow Friday 11th until 11.00am on Monday 14th, extra time should be allowed when travelling to Shannon Airport due to increased traffic volumes,’ the airport’s authority wrote.

‘All visitors to the airport during this period are required to carry a valid photo ID. Passengers should also have their photo ID and flight documentation ready for inspection when approaching the airport.’

As well as rolling road closures in Dublin, Doonbeg has also seen huge security measures being brought in. Gardaí from outside of the Clare division have been enlisted for what’s been described as an extraordinary policing event.

Security sources have described the operation as one of the most complex ever undertaken in the State, with signal-jammers to disrupt drones, extensive weapons checks for spectators, and advice from gardaí not to rely on satnav due to widespread road closures around the course.

Speaking at the Open in Doonbeg, Rory McIlroy said: ‘I think the weekend, especially when he’s here [will feel different]. Crowds will be limited. Obviously, there’s a lot that goes on. So, logistically, it provides some challenges, absolutely. But at the same time, if [Mr Trump] wants to come and watch the Irish Open, who are we to say no?’

Taoiseach Micheál Martin said on Wednesday ‘a lot of preparatory work’ had been undertaken on the country’s counter-drone capabilities, stating that An Garda Síochána had ‘resourced the situation very significantly’ in terms of on-land capability.

However, he added: ‘There is more to do offshore, and that work is under way.

‘That procurement is under way and that’s a very active programme that is being pursued.

‘But certainly, An Garda Síochána in advance of the EU presidency had secured the drone technology capacity that they required.’
