Speaking in Iowa Wednesday, former Secretary of State Hillary Clinton said that all her grandparents had immigrated to the United States, a story that conflicts with public census and other records related to her maternal and paternal grandparents.

The story of her grandmother specifically immigrating is one Clinton has told before. Clinton's sole foreign-born grandparent, Hugh Rodham Sr., immigrated as a child.

"Her grandparents always spoke about the immigrant experience and, as a result she has always thought of them as immigrants," a Clinton spokesman told BuzzFeed News. "As has been correctly pointed out, while her grandfather was an immigrant, it appears that Hillary's grandmother was born shortly after her parents and siblings arrived in the U.S. in the early 1880s."
