WASHINGTON -- Sen. Lindsey Graham, the son of pool hall owners who rose to become one of his generation’s more influential U.S. politicians at home and abroad, was eulogized Tuesday as "a true American original" during memorial services in Washington. Later, President Donald Trump joined foreign leaders for a funeral at Washington National Cathedral, a testament to Graham’s stature on the global stage. Trump called Graham "a giant of the United States Senate, a true American original who left us much too soon." It was the start of two days of services, with burial Wednesday in Graham’s home state of South Carolina. Graham died suddenly on July 11 at his home in Washington of a likely aortic tear, according to preliminary findings.
