COLUMBIA, S.C. (AP) — Sen. Darline Graham said Monday she’s running for a full term to replace her late brother Lindsey Graham’s Senate seat.“I’ve made a decision,” Darline Graham told Fox News Channel host Sean Hannity, according to a clip released of an interview set to air later Monday. “I’m in.”The entrance of Darline Graham — sworn in last week to fulfill the remaining months of her late brother’s term, which expires in January — into the Republican scramble to select a new Senate nominee further complicates an already rushed process following Lindsey Graham ‘s death earlier this month. A weeklong filing period opens Tuesday for the special Republican primary, which will be Aug. 11. On Friday, President Donald Trump said that Darline Graham had his “Complete and Total Endorsement” to seek the nomination, adding, “RUN, DARLINE, RUN!”Last week, Gov. Henry McMaster appointed Darline Graham to serve the remainder of her brother’s term, which ends in January. In his announcement, McMaster made no reference to Darline Graham as a placeholder or symbolic appointment, although a person familiar with McMaster’s thinking but unauthorized to speak publicly said the governor, in selecting Darline Graham, had never contemplated that she would run for the seat herself.
