Sen. Lindsey Graham’s only surviving family member spoke briefly with The Post on Monday about the loss of her brother following a heart attack Saturday night.

“Actually, I’m just kind of like devastated right now,” said Darline Graham Nordone in a brief phone call.

President Trump posted on his Truth Social minutes before that he had recommended Graham’s “wonderful sister” to serve as interim senator until a special election can be held.

South Carolina Republican Gov. Henry McMaster will be choosing that replacement. He’s scheduled a 4 pm press conference to make that announcement.

“This would be a fabulous tribute to Lindsey, who loved her dearly!” Trump added.
