'It's the classic glass half empty': Sen. Bernie Sanders hidden health records raise questions

More than four months after suffering a heart attack on the campaign trail, Sen. Bernie Sanders refuses to release detailed medical records that might yield clues about his overall health. Sanders, 78, said multiple times last year that he would share his medical records. On Dec. 30, he released three paragraphs from two cardiologists and a two-page letter from a primary care doctor proclaiming him to be in good health.
