Defense Secretary Lloyd Austin was hospitalized Sunday following symptoms pointing to an "emergent bladder issue," the Pentagon said. In a statement, the Pentagon said Austin was transported by his security detail to Walter Reed National Military Medical Center around 2:20 p.m. He "is retaining the functions and duties of his office," according to Pentagon press secretary Maj. Gen. Pat Ryder, who added that the deputy defense secretary has been notified and is prepared to assume Austin's duties "if required."
