Donald Trump made a high-profile visit to Doonbeg in County Clare during the final round of the Irish Open, overshadowing Shane Lowry's dominant victory on home soil with heavy security and intense media attention. The scale of the operation—sniffer dogs, bag checks and restrictions on umbrellas—alongside the presence of figures such as Taoiseach Micheál Martin, his son Eric Trump and businessman Denis O'Brien, underlined how thoroughly the president's presence dominated the event, leaving spectators and even the eventual champion competing for attention.

Lowry, who first won the tournament as an amateur in 2009, cruised to victory after a difficult season, reaching 19 under par by the seventh hole. Trump used the occasion to repeat comments made the previous day about wanting a united Ireland and to needle new British prime minister Andy Burnham, while declining to comment on Scottish independence. He also teased an unspecified announcement "next week" in response to a supporter shouting "four more years", and was seen mixing with the crowd and press before watching play from the 18th hole.
