The sudden death of Sen. Lindsey Graham has thrust a spotlight back on one of Washington's most uncomfortable questions: Are America's aging political leaders telling the public enough about their health?
Graham, one of Donald Trump's closest allies in Congress, died Saturday night at 71 after suffering an aortic dissection, according to preliminary medical findings. His death came just two days after his birthday and shocked Washington because he appeared to be in good health despite being younger than many of his Senate colleagues.
