Jeff Flake, R-Ariz., who served in the Senate with Kyl, also paid homage to the late lawmaker.”Arizona has lost a giant. Jon Kyl was one of the most diligent and effective public servants Arizona has ever had. I was honored to follow him in the U.S. Senate, where his example of seriousness, integrity and devotion to public service was known to all. Cheryl and I send our deepest condolences to Caryll and the entire Kyl family,” Flake posted on X. Flake also gave remarks to reporters at the Capitol on Thursday. “I admired him from the get go, when he was back in the house, and I was in Arizona. When I ran for office, he gave me the best advice I ever got. He said that, when you get back to Washington, make sure your family is aware of what you’re doing, is involved in it. He said they will either resent it or revel in it. And that was the best advice I got, because we tried to follow that. And he was just… in addition to being an extremely effective public servant, he was a good man. And I think that, that shined through,” Flake told reporters.TILLIS’ RETIREMENT ANNOUNCEMENT DRAWS REACTIONS FROM TRUMP CRITIC JEFF FLAKE, BERNIE SANDERS: ‘A CULT'”For Arizona, you know, every Western state has similar issues; water issues, public land issues. And Jon took that on,” Flake said. “That’s the workhorse in him. I think he did nine Indian water settlements during his time, which has allowed the Indian tribes in Arizona to have the water they need and also for the state to grow sustainably,” Flake continued.”And then also, in terms of his legal mind and his, you know, concern about the Supreme Court. And he was asked after he had left Congress to Sherpa certain nominees through and he was extremely effective in that because he had the respect of his colleagues.”Flake also revealed that he last spoke with Kyl just before the late Senator announced his dementia diagnosis “December of last year he put out a statement, I had talked to him just before that. And, it was a wonderful conversation. He was very much aware of all that the state had gone through, and I made sure to tell him how appreciative all Arizonans are of what he did for the state and what he did for the country. And, he was so devoted to his wife, Carol, and his family, and the state of Arizona,” Flake said. Flake also commented on the unique situation that arose when Kyl was appointed to replace McCain.”When Senator McCain passed away, there was an appointment and he served out that term for the last few months. So I got to serve with him in the Senate and also jokingly be the senior Senator to him, which I didn’t deserve. But it was just a wonderful relationship throughout,” Flake said. This is a developing story. Please check back for updates.
