WASHINGTON (AP) — President Joe Biden is marking St. Patrick’s Day as he meets virtually with Ireland’s prime minister and recommits U.S. support for the Good Friday Agreement. That agreement was signed in 1998 and helped end sectarian violence that had raged for decades over the issue of Northern Ireland unifying with Ireland or remaining part of the United Kingdom. The agreement has come under increasing stress following the U.K.’s exit from the European Union. The White House calls the agreement “the bedrock of peace, stability, and prosperity.” Biden attended a Mass near his Delaware home Wednesday morning before returning to the White House for St. Patrick’s Day celebrations toned down because of the coronavirus pandemic.
