Sen. Lindsey Graham, the influential South Carolina Republican who spent more than two decades in the U.S. Senate and evolved from a leading advocate of bipartisan immigration reform into one of President Donald Trump's closest allies, has died at the age of 71 following what his office described as a "brief and sudden illness."
Graham's office announced his death late Saturday but did not disclose the cause. President Donald Trump led a bipartisan wave of tributes, calling Graham "one of the greatest people and Senators I have ever known" and "a true American Patriot." Senate Majority Leader John Thune praised him as a tireless defender of American leadership and national security.
