The US House of Representatives is set to vote on a resolution that would reaffirm support for the Good Friday Agreement (GFA).
It states that the US Congress “greatly values” the relationship shared between the US, the UK and the Republic of Ireland.
Votes are due to take place in the House of Representatives at 6.30pm today (11.30pm Irish time).
The resolution says Brexit does not appropriately protect the GFA and threatens to undermine the process that has been made in moving “beyond the legacy of the past in Northern Ireland”.
The US vote would reaffirm support for the GFA and other agreements to ensure peace in Northern Ireland.
