As Vice President Joe Biden hosted the Irish prime minister at a St. Patrick's Day breakfast Thursday, his office called attention to his own heritage in a statement referring to him as "the first Irish-American U.S. Vice President."
That's not even close.
Many previous vice presidents have family trees linked back to Ireland. John Calhoun, who held the office from 1811 to 1817, had parents who both immigrated to South Carolina from the Irish county of Donegal. Chester A. Arthur, who moved from VP to president after the assassination of James Garfield in 1881, had an Irish father.
More recently, Lyndon Johnson, Richard Nixon, George H.W. Bush and Al Gore claim Irish as part of their lineage.
