The White House Press Secretary Jen Psaki has said that the Biden administration is continuing to closely monitor issues in Northern Ireland.

"We welcome the provisions of the trade deal between the United Kingdom and the European Union and the Northern Ireland protocol ... which will help to protect the gains of the Belfast/Good Friday Agreement," she said.

Ms Psaki was responding to a question about the appointment of a US Special Envoy to Northern Ireland and said that she had no personnel decisions to announce at this time.

Earlier this month, 25 members of the United States Congress signed a letter to President Biden calling on him to appoint a US Special Envoy to Northern Ireland.

"We believe this decision would not only demonstrate America's enduring commitment to peace in Northern Ireland but would directly encourage regional peace and stability," the letter stated.

Last night, Minister for Foreign Affairs Simon Coveney discussed Brexit and Northern Ireland with the US National Security Adviser Jake Sullivan during a meeting at Shannon Airport.

"Mr Sullivan and Foreign Minister Coveney reaffirmed their commitment to protecting the gains of the Good Friday Agreement for all communities in Northern Ireland," according to a statement released following the meeting.
