Sen. Darline Graham, a Republican from South Carolina, has confirmed she intends to seek a full term in the Senate, telling Fox News host Sean Hannity of her plans in an exclusive interview. The announcement follows her sudden elevation to the Senate after the death of her brother, former Senator Lindsey Graham, and settles speculation about whether she would serve only as a caretaker or pursue the seat in her own right.

Darline Graham was sworn into office last week following her brother's unexpected death, making her the first woman to represent South Carolina in the US Senate. Her decision to run for a full term in the autumn sets up a contest that will be closely watched given the family connection and the historic nature of her appointment.
