President Donald Trump said on Truth Social that he wants Darline Graham Nordone to temporarily fill the U.S. Senate seat of her brother.

The move comes after the death of Senator Lindsey Graham (R-SC) on July 11, 2026 [2]. Because the vacancy occurs in a high-profile seat during a period of political volatility, the appointment process carries significant weight for the balance of power in Washington.

Trump's public endorsement of Nordone, the sister of the late senator, creates a public expectation for the state's leadership to follow the president's preference. However, the legal authority to appoint a temporary replacement rests with the governor of South Carolina, not the president.

Governor Henry McMaster is expected to announce his official pick at 4 p.m. ET today [1]. While Trump has expressed his wish for Nordone to serve, the governor's office has not yet confirmed if the president's request will dictate the final selection.

Reports on the timing of the appointment have varied. Some sources indicate the governor is preparing the announcement for this afternoon [1], while other reports suggest a replacement was named Monday afternoon following the death of Graham on July 11 [2].

Nordone would enter the Senate as a temporary appointment to maintain South Carolina's representation until a formal election, or further legal process, determines a long-term successor. The transition follows the death of Graham, who served as a prominent voice in the Republican party and a close ally of the president.

The situation highlights the tension between presidential preference and state-level appointment power. While the president can influence public opinion and party loyalty, the South Carolina governor holds the constitutional authority to fill the vacancy. If McMaster deviates from Trump's public request, it could signal a rift in state-federal Republican coordination; conversely, appointing Nordone would solidify the president's influence over the state's legislative representation.
