Israeli politicians turned to social media to share their sorrow after the sudden death of Republican US Senator Lindsey Graham was announced on Sunday.

Prime Minister Benjamin Netanyahu and his wife Sara issued a statement mourning Graham on Sunday.

"Lindsey recognized that Israel's security and America's are tightly linked. He spent his career protecting America, bolstering the alliance and defending the free world," Netanyahu stated. "Israel has lost one of its greatest friends. America has lost a great patriot. I have lost a beloved friend."

"Our hearts go out to Lindsey's family and the American people during this hard time. May his values and work continue to lead us to victory and peace, and may his memory be a blessing forever," the statement continued.

"I am shocked and heartbroken to learn of the sudden passing of the great American patriot, a great friend of Israel, and my dear friend US Senator Lindsey Graham," President Isaac Herzog posted on X on Sunday morning.

Herzog described Graham as "a beacon of moral clarity and a true leader of the US-Israel partnership."

"We will never forget how he stood by the people of Israel in our most difficult moments, and we will remain eternally grateful for his sense of justice, truth, and loyalty," he wrote. "The people of Israel mourn his loss, and I will miss my great friend very dearly."

National Security Minister Itamar Ben-Gvir called Israel the loser of "one of its greatest friends" in an English-language post on X on Sunday.

"Senator Lindsey Graham stood with Israel not because it was easy, but because he believed it was right. His unwavering support, courage, and moral clarity earned him the admiration of millions of Israelis," Ben-Gvir wrote. "The State of Israel will always remember his friendship, his unwavering support, and his steadfast commitment to Israel's security."

Ben-Gvir ended by offering condolences to Graham's family and the American people.

"May his memory be a blessing."

Defense Minister Israel Katz said he was "deeply saddened by the passing of Senator Lindsey Graham."

Katz added that Graham was one of Israel's "strongest and most steadfast supporters" and "was an unwavering voice in support of Israel's security and its right to defend itself."

"Following the October 7 massacre, he traveled to Israel time and again, standing shoulder to shoulder with our people in an extraordinary demonstration of solidarity and unwavering friendship. His repeated visits during one of the darkest chapters in Israel's history reflected his deep commitment to the Jewish state and its right to live in peace and security."

Foreign Minister Gideon Sa'ar posted on X that he always called Graham "the best senator and the best friend."

"Lindsey was a man with a huge heart and rare personal charm. He was blessed with a clear vision of reality and a true commitment to values. His support for Israel and its security was unwavering."

"The State of Israel has lost a great friend," Sa'ar said. "Israel will not forget you, dear friend."

Graham 'stood with Israel in its darkest hours'

Former prime minister Naftali Bennett shared similar feelings in his post on X.

"I am heartbroken to hear of the passing of my friend Senator Lindsey Graham. America has lost a devoted patriot, and Israel has lost one of its greatest friends," Bennett wrote. "Lindsey stood with Israel through our darkest hours, with courage. My thoughts and prayers are with his family."

Opposition head Yair Lapid noted that Graham "had unwavering moral clarity, a deep devotion to the people of Israel and a clear vision for a secure and peaceful Middle East."

"His warmth, humor and energy will be deeply missed," he said, sending prayers to Graham's family.

Ultra-Orthodox Shas party leader Arye Deri said he was also "deeply saddened to hear of the passing of Senator Lindsey Graham, one of the greatest friends of the State of Israel and Righteous Among the Nations of our generation."

"He stood courageously by Israel's side, fought uncompromisingly against the Iranian axis of evil and terrorism, and made a significant contribution to strengthening the strong alliance between Israel and the United States."

'One of a kind'

Knesset Speaker Amir Ohana sent condolences on behalf of the Knesset to Graham's family and South Carolina in an X post on Sunday.

"Lindsey was one of the funniest and smartest people I've ever met. He was a great friend of the State of Israel, and to me personally," Ohana wrote. "He was one of a kind, and he will be dearly missed. Rest in peace, friend. Thank you for fighting for what is good."

Samaria Regional Council Head Yossi Dagan said he was "filled with sorrow over the sudden passing of Lindsey Graham," praising Graham for his love of Israel and idealism.

"He was a true lover of Israel and an idealist. A man who believed, out of Christian faith, that the Jews should return to the Land of Israel, and worked for decades for the State of Israel and strengthening the bond between Israel and the United States," Dagan said. "Whoever blesses the people of Israel is blessed, and he blessed the people of Israel from the bottom of his heart, without ceasing."

Dagan noted Graham's position as a "declared friend of Samaria," adding that the senator was one of the official hosts of the West Bank conference held in Washington last month.

Finance Minister Bezalel Smotrich, Innovation, Science, and Technology Minister Gila Gamliel, Yisrael Beytenu head Avigdor Liberman, and MK Eli Cohen (Likud) all also offered their condolences over Graham's passing.
