The €20 million cost of Donald Trump’s trip to play golf in County Clare means it will probably be the 'highest cost for any sporting event in Irish history', the General Secretary of the Irish Trades Union Congress has said. “I don't think there'll be any welcome for Donald Trump - obviously, he is the elected president of the United States. Given his status as US President, Mr Trump is a particular security risk and 4,000 Gardaí are expected to be drafted in to ensure his safety. “It's going to be the highest cost for security for any sporting event in our history. While in Ireland, Mr Reidy urged any politician who meets Mr Trump to challenge him robustly on his policies.
