Lindsey Graham has evolved from a sharp-tongued House impeachment manager during the Clinton years to one of the Senate's most prominent foreign policy hawks, consistently advocating for robust American military intervention abroad. The South Carolina Republican built his career as a military lawyer and Air Force Reserve colonel, bringing that perspective to his unwavering support for defense spending and interventionist policies. Graham is known for his ability to work across the aisle on immigration reform and climate issues, though he has also emerged as one of Donald Trump's most vocal defenders after initially being a fierce critic during the 2016 primary. His quick wit and frequent media appearances have made him one of the most recognizable faces in the Republican Party's foreign policy establishment.
