Today on Face the Nation, breaking overnight: Republican Senator Lindsey Graham has died from what his office calls a "brief and sudden illness" at the age of 71. We'll have the latest and we'll talk with fellow South Carolina Senator Tim Scott about his impact in Washington and beyond.

Plus, new developments overseas as U.S. Central Command has launched a new wave of strikes against Iran after its military force attacked a container ship in the Strait of Hormuz, in defiance of U.S. demands to keep the waterway open. What's next for the security of the region, after President Trump declared that fragile ceasefire deal to be "over"? We'll be joined by former CENTCOM commander Frank McKenzie, Republican Ohio Congressman Mike Turner, and Israel's Ambassador, Dr. Michael Leiter.

We'll also talk with Democrat Rahm Emanuel, who's just back from delivering a speech in Tel Aviv about the future of U.S.-Israeli relations.

It's all just ahead, on Face the Nation.
