Sen. Darline Graham is serving the remaining months of her late brother Lindsey Graham's Senate term, but she's weighing a possible run for a full term.

The Senate will swear in Darline Graham on Tuesday to finish the remainder of her late brother Lindsey Graham's term, according to a person familiar with the matter.

The sister of the late South Carolina Sen. Lindsey Graham will soon be sworn in to fill the seat, just three days after her brother’s death.
