The First Lady, Michelle Obama, introduces the President at Waterfront Hall in Belfast, Northern Ireland. Fifteen years after the signing of the Good Friday peace agreement which cleared the way for the power-sharing executive in Belfast, the US president said the world was watching for the next stage of the process.
He hinted it was time for an end to segregated education and housing.
He said: "You need to get this right. You set the example for those who are seeking peace to end conflicts of their own.
"You are their blueprint to follow. You are the proof of what is possible. Hope is contagious. They are watching to see what you do next."
During an uplifting keynote address to an invited audience of 2,000 people, mainly school students, Mr Obama lauded the Northern Ireland peace process as a model and promised that America would continue to support the Stormont political system. Report by Katie Lamborn.
