US vice president Mike Pence has firmly put his support behind Boris Johnson calling on Ireland and the EU to "negotiate in good faith" on Brexit.
Speaking after meeting with Taoiseach Leo Varadkar in Farmleigh House, in Dublin, Mr Pence said the EU must work with the UK to minimise economic disruption in Britain.
While Mr Pence said the Good Friday Agreement must be protected, he added that America stands behind the UK's decision to leave the EU.
"Let me be clear. The United States supports the United Kingdom's decision to leave the European Union in Brexit," he said. "But we also recognise the unique challenges on your northern border.
"And I can assure you we will continue to encourage the United Kingdom and Ireland to ensure that any Brexit respects the Good Friday Agreement.
"As the deadline for Brexit approaches we urge Ireland and the European Union as well, to negotiate in good faith with Prime Minister Johnson, and work to reach an agreement that respects the United Kingdom's sovereignty and minimises the disruption to commerce."
Mr Pence added: "The United States will look to play whatever hopeful role we can play. As President Trump announced last week, when Brexit is complete, the United States will have a new trade agreement with the United Kingdom."
