Lindsey Olin Graham is the senior United States senator from South Carolina, serving in the Senate since 2003 after earlier service in the U.S. House. An attorney by training, Graham is also a longtime military legal officer, having served in the U.S. Air Force JAG Corps and later the Air Force Reserve, ultimately retiring as a colonel.
Graham built his national profile through the Judiciary and national security ecosystem known for aggressive oversight, prosecutorial instincts, and an interventionist foreign policy worldview. He chaired the Senate Judiciary Committee from 2019 to 2021 and has been a major player in Supreme Court confirmation fights and high-stakes legal showdowns.
Ideologically, Graham is a mainstream conservative with a distinctly hawkish brand on defense and foreign policy. He has also been a recurring bipartisan dealmaker at moments, especially on immigration negotiations, while drawing criticism for high-profile reversals and tactical alliances inside the GOP, including a widely noted evolution in his relationship with Donald Trump after 2017.
With deep ties to defense, aerospace, and national security networks, Graham has remained one of the party’s most visible messengers on military spending, sanctions policy, and U.S. posture toward rivals. He is running for re-election in 2026.
