US President Donald Trump arrived at Dublin Airport on Saturday morning for a two-day visit to Ireland, a trip marked by a significant security operation. He was greeted by Ireland's Finance Minister Simon Harris upon deplaning Air Force One.

The President's itinerary includes meetings with Irish President Catherine Connolly and Taoiseach Micheál Martin. Engagements are scheduled in Dublin and at his golf resort in Doonbeg, County Clare, which is hosting the Irish Open.

Taoiseach Martin expressed anticipation for the visit, stating he looked forward to discussing mutual interests and reaffirming the strong ties between Ireland and the United States. He also noted the visit coincides with a notable sporting period for Ireland and hoped for an Irish winner at the Irish Open.

Trump is expected to meet President Connolly at her official residence, Áras an Uachtaráin, and later meet with Mr. Martin at the Farmleigh Estate. The US Ambassador to Ireland, Edward Walsh, hosted an event at his residence, Deerfield, attended by hundreds of guests including former Irish premiers and business leaders.

A large-scale security operation is in place, described as one of the biggest ever implemented by the Irish police. Garda Commissioner Justin Kelly confirmed that while peaceful protest would be facilitated, there would be no tolerance for public disorder or attempts to disrupt the President's movements. Water cannon are reportedly on standby.

Despite the official welcome, the visit has drawn criticism and planned protests from some residents. Concerns have been raised about the disruption caused by the security measures and about President Trump's policies and attitudes. Taxi driver Christopher Fox voiced frustration over the city's disruption, while university student Mina Petrovski criticized the government for welcoming the President.

The visit follows an invitation extended by Mr. Martin during a meeting at the White House on St. Patrick's Day earlier in the year. Irish political leaders view the trip as an opportunity to maintain trans-Atlantic relations, even amidst discussions on trade and foreign policy issues that the White House indicated Trump wishes to address.
