Irish Government Ministers travel abroad on official visits to various countries around the globe to celebrate St Patrick's Day and promote Ireland. The most prominent of these is the visit of the Irish Taoiseach (Irish Prime Minister) with the U. S. President which happens on or around St Patrick's Day. Traditionally the Taoiseach presents the U. S. President a Waterford Crystal bowl filled with shamrocks. This tradition began when in 1952, Irish Ambassador to the U. S. John Hearne sent a box of shamrocks to President Harry S. Truman. From then on it became an annual tradition of the Irish ambassador to the U. S. to present the St Patrick's Day shamrock to an official in the U. S. President's administration, although on some occasions the shamrock presentation was made by the Irish Taoiseach or Irish President to the U. S. President personally in Washington, such as when President Dwight D. Eisenhower met Taoiseach John A. Costello in 1956 and President Seán T. O'Kelly in 1959 or when President Ronald Reagan met Taoiseach Garret FitzGerald in 1986 and Taoiseach Charles J. Haughey in 1987. However it was only after the meeting between Taoiseach Albert Reynolds and President Bill Clinton in 1994 that the presenting of the shamrock ceremony became an annual event for the leaders of both countries for St Patrick's Day.
