The sudden death of Sen. Lindsey Graham is renewing focus on the country’s aging lawmakers. Graham had turned 71 just two days before dying on Saturday. The senator appeared to have been in good health but suffered a tear in his aorta. Meanwhile, in early June, former Republican Senate leader Mitch McConnell was hospitalized for undisclosed reasons — revealed weeks later to be a fall. Graham’s death and the 84-year-old McConnell’s hospitalization come amid a reckoning about the nation’s aging leaders. Sen. John Cornyn says more health transparency may be needed.
