To ensure that "Brits don't screw around," Biden said, he travelled to Ireland.

Joe Biden's four-day visit to Ireland marked the 25th anniversary of the Good Friday Agreement, a 1998 political deal that ended decades of conflict between Catholic and Protestant factions in Northern Ireland. The White House released a statement to say both leaders had "reaffirmed their shared commitment" to the Good Friday Agreement. Biden called on Northern Irish lawmakers to re-establish the power-sharing accord enshrined in the Good Friday Agreement in 1998. He also suggested that Downing Street should work closer with Dublin to support issues in Northern Ireland. A new Brexit trade deal was greenlit by the UK and EU in March, but the DUP has not yet dropped its protest.
