Tony Rodham, Hillary Clinton's youngest brother, has died. He was in his mid-sixties.
Clinton announced her brother's death in a tweet Saturday. It wasn't immediately clear how Rodham died.
Clinton said: "It's hard to find words, my mind is flooded with memories of him today... We'll miss him very much."
Rodham worked with the Democratic National Convention during former President Bill Clinton's 1992 campaign, as well as Hillary Clinton's 2007 presidential campaign.
Rodham is survived by his wife and three children.
