WASHINGTON (AP) — Senate Republicans will return 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 with President Donald Trump.

Graham, 71, died Saturday evening after a tear in his aorta, according to a statement from his office on Sunday. The shocking news came after 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 evening, saying that he was still recovering after suffering from pneumonia and falling in his home.
