Senator Lindsey Graham, who was a leading voice in US foreign policy in recent decades, died suddenly on Saturday evening at age 71. The South Carolina Republican had just returned to Washington from Ukraine, where he had continued his advocacy for increased US support for the country’s fight against Russia’s invasion. Graham, who appeared at the Atlantic Council in 2015 to deliver the first foreign policy speech of his presidential campaign, was one of Congress’s most prominent hawks across eight years in the House and twenty-three in the Senate. Below, members of the Atlantic Council network share their remembrances.
