U.S. President Bush will not invite Sinn Fein or Irish Republican Army officials to the White House on St. Patrick's Day. Instead, Bush has invited the sisters and fiancee of a Catholic man said to have been killed by the IRA. The invitation is a significant political message from Bush, whose aides announced last week for the first time since 1995, Sinn Fein and other Irish parties would not be invited. Bush believes neither Adams nor his aide Martin McGuinness can be trusted. Gerry Adams, the leader of Sinn Fein, the political arm of the separatist group, will be touring the United States when Ireland's patron saint is honored March 17, and will speak in Washington, although he was not invited to the White House. McGuinness will remain back in Northern Ireland to tend to various crises.
