Former First Lady Jill Biden says she was “just shocking” when her husband, former President Joe Biden, was diagnosed with prostate cancer last year. In a preview clip of an interview with CBS News’s Rita Braver, Jill Biden discusses the reaction to the diagnosis and whether it could have been detected earlier. She acknowledges that she believes the White House provided “amazing care,” but she says the cancer finding was somehow “missed.” The interview references that Joe Biden disclosed his diagnosis last May and that a White House physician’s oversight was a point of question in the conversation. The sources report that the exchange focuses on Jill Biden’s personal reaction and her view that despite strong medical care, the diagnosis was not identified sooner. CBS reports that more of the interview will air on Sunday.
