President Donald Trump is pushing for an unexpected replacement to fill the vacancy left by the late Sen. Lindsey Graham, R-S.C., in the Senate.

Trump wants South Carolina Gov. Henry McMaster to tap Graham’s sister, Darline Graham Nordone, to be appointed to the lawmaker’s suddenly open seat for the remainder of his term.

"I recommended, to Governor Henry McMaster, Lindsey Graham’s wonderful sister, Darline, to serve as interim Senator from the Great State of South Carolina," Trump said on Truth Social on Monday. "This would be a fabulous tribute to Lindsey, who loved her dearly!"

Graham and his younger sister, Darline, had a unique bond, given that, after their parents died, the lawmaker legally adopted and raised her.

Trump’s announcement comes as a scramble behind the scenes is taking place to fill Graham’s spot, and further, find a new GOP nominee to run in November to keep his seat in the hands of Republicans.

McMaster is expected to announce his pick for the seat at 4 p.m. on Monday. He has so far kept quiet about who he would prefer. Fox News Digital did not immediately hear back from McMaster’s office on who he is eyeing in the interim.

Meanwhile, a key Republican, Sen. Tim Scott, R-S.C., also wants to see Graham's sister get the nod for his seat.

"Lindsey Graham’s sister, Darline Graham Nordone, would be a fantastic pick to serve out the remainder of the Senate term," Scott said on X. "After speaking with Darline, there is no one better who understands Lindsey’s love for family, our state, and our country."

Scott, earlier in the day, floated both former Rep. Trey Gowdy and former Sen. Jim DeMint as possible replacements in the interim. He hoped that McMaster would "put a placeholder and let the voters decide" later during a forthcoming special election.

"I think in the next several hours or next day or so we'll figure out who that person is," Scott said. "I love Trey Gowdy and Jim DeMint has been in the conversation."

"[Graham’s] sister would be a wonderful placeholder as well," he continued. "So we've got lots of candidates who could hold the place so that the voters decide. And remember the election starts August the 11th in South Carolina, three weeks from now, we'll have a primary process."

Both Gowdy and DeMint have served in Congress — Gowdy in the House and DeMint in the Senate, preceding Scott. Graham Nordone, however, has never held public office.

Multiple sources close to Scott, who chairs the National Republican Senatorial Committee (NRSC) told Fox News Digital that he is pushing McMaster to choose one of the three to effectively be a placeholder and not seek a six-year term in the Senate.

While the appointment race nears its conclusion, the race for the GOP nomination to run in South Carolina is still wide open.

Reps. Nancy Mace, R-S.C., and Ralph Norman, R-S.C., are already hinting at leaping into the special election, which is set for Aug. 11. Rep. Joe Wilson, R-S.C., said that he would stay in the House, but the rest of the Palmetto State’s GOP congressional delegation have not said what their plans are.
