President Trump has recommended Lindsey Graham's sister, Darline Graham Nordone, to serve as interim Senator from South Carolina.
Governor Henry McMaster will announce Lindsey Graham's replacement at 4 pm ET on Monday.
Trump expressed his support for Darline Graham Nordone on his social media platform, stating that she would make a "fabulous tribute" to Lindsey, who loved her dearly.
Lindsey Graham, a 71-year-old senator, passed away on Saturday night after experiencing chest pains.
The DC Medical Examiner has released preliminary findings indicating that Graham's death was due to Aortic Dissection caused by Arteriosclerotic Cardiovascular Disease.
The death certificate will be pending until further toxicological and microscopic testing is completed and finalized.
The FBI is assisting local authorities in investigating Graham's death, but foul play is not suspected at this time.
President Trump praised Lindsey Graham as one of the greatest people and senators he has ever known, describing him as a true American Patriot who will be greatly missed.
