Thune pays tribute to Graham

Senate Majority Leader John Thune (R-SD) paid tribute to the late Sen. Lindsey Graham (R-SC) on the Senate floor Monday, during the chamber's first session since the senator unexpectedly died of an aortic dissection.

"It's difficult to believe that Lindsey Graham is no longer here with us," Sen. Thune said. "The halls of the Senate already feel empty without him — and I know I'm not alone in that feeling."
