Joe Biden has said he will not allow peace in Northern Ireland to become a “casualty of Brexit” if he is elected US President in November.
The Democratic candidate said any UK-US trade deal had to be “contingent” on respect for the Good Friday Agreement.
Foreign Secretary Dominic Raab has been trying to reassure US politicians about the latest Brexit developments during a trip to Washington.
US Secretary of State Mike Pompeo said he trusted the UK to “get this right”.
But US Speaker Nancy Pelosi said there was “no chance” of a UK-US trade deal getting through the US Congress if the UK violated international agreements, undermining the Good Friday Agreement.
After a meeting with Mr Raab, the Speaker of the House of Representatives said the UK’s exit from the EU could not be allowed to “imperil” peace in Northern Ireland.WP: US authorities transporting live ammunition to the capital during protests outside the White House
