Lindsey Graham's sister Darline Graham Nordone announces run for his Senate seat

Darline Graham Nordone, sister of the late Senator Lindsey Graham, has officially announced her candidacy for the full Senate term to succeed her brother. She was appointed as his interim replacement last week following his death from an aortic tear. Nordone now seeks to win the seat in her own right, following in the footsteps of one of the Republican Party's most prominent senators.
