Darline Graham, who became South Carolina senator after her brother’s sudden passing, attended a high-powered dinner hosted by Lebanese banker Antoun Sehnaoui and former U.S. envoy Morgan Ortagus at the Four Seasons in Washington, D.C., on Monday, reports Axios’ Barak Ravid. The dinner was held in honor of the late Republican firebrand, who died at age 71 earlier this month. Other participants included Miller’s wife, Katie; former national security adviser Dina Powell McCormick; and Israeli ambassador Yechiel Leiter. Darline, 62, became South Carolina’s first female senator on July 14 after she was appointed to fill the vacancy left by her brother. Graham died while chasing a fifth term in Senate; Darline, meanwhile, has never run for office but now faces an uphill battle to win the special Republican primary on Aug. 11.
