A Pentagon mystery: Why was Defense Secretary Lloyd Austin's hospital stay kept secret for days?

U.S. officials says that members of Congress and top Pentagon leaders were unaware for days that Defense Secretary Lloyd Austin had been hospitalized since Monday. And now questions are swirling about his condition and the secrecy surrounding it. It remains unclear when the White House and other key U.S. officials were told about Austin's stay at Walter Reed National Military Medical Center. The Pentagon’s failure to disclose Austin’s hospitalization for days reflects a stunning lack of transparency. Such secrecy, at a time when the United States is juggling myriad national security crises, runs counter to normal practice with the president and other senior U.S. officials and Cabinet members.
