WASHINGTON (AP) — Senate Republicans returned to Washington on Monday with an uncertain agenda after the sudden death of prominent Republican Lindsey Graham, a committee chairman and key player who served as a crucial ally of President Donald Trump. Graham, 71, died Saturday evening after a tear in his aorta, according to a statement from his office Sunday. The shocking news came as another prominent Republican senator, former Republican leader Mitch McConnell, has been hospitalized for almost a month. McConnell broke a weekslong silence about his health Sunday, saying he was still recovering after suffering from pneumonia and falling in his home.The continued absence of McConnell, R-Ky., and the surprise death of the South Carolina senator have shaken Republicans who were already at odds with Trump and stalled on several priorities as they return from a two-week recess. And the reduced Republican numbers in the 53-47 Senate are sure to add confusion to what was already expected to be a chaotic and difficult few months before the November midterm elections.

Despite consolidated power in Washington, Republicans have been unable to move much of their legislation forward as the Senate, House and White House have disagreed on legislative priorities and as Trump has criticized Senate Republicans, in particular, for not passing his legislation to require proof of citizenship for voters. Graham, who was one of Trump’s closest friends in the Senate, often served as a pivotal intermediary.“He was a great — like a gauge, a temperature gauge of the Senate,” Trump said of Graham on NBC’s “Meet the Press” on Sunday, noting he had talked to Graham on Saturday. “He could go in and get something approved. He would just get people on his side.”
