John Steven Whitaker was the first husband of Karen Pence, the wife of Vice President Mike Pence.
Whitaker, who would become a doctor, was Pence's high school sweetheart. Dr John Steven Whitaker married Karen Batten in 1978, but they divorced soon after.
They split up when Whitaker was a medical student and his schedule became too intense, according to The List.
Karen met Mike Pence at Mass at St. Thomas Aquinas Church in Indianapolis and the two got engaged in 1984.
