The First Minister of Northern Ireland Peter Robinson praised US Secretary of State Hillary Clinton for her "instrumental" role in the peace process.
He said: "Very often, we will sit down, and somebody will mention someone who has claimed to be instrumental in the peace process, and Martin and I look at each other, and say 'Do you know them?'
"But you are one person who has consistently helped us. You have been a great friend to Northern Ireland."
Hillary Clinton wanted to be President but she became America's top diplomat instead. Her job was to reset US relations around the world.
Hillary Clinton condemned a wave of street violence in Northern Ireland during a state visit to Belfast.
