U.S. Secretary of Defense Lloyd Austin was admitted to the intensive care unit at the Walter Reed National Military Medical Center in Virginia due to a bladder problem, the Pentagon announced. The statement did not provide details on how long she will remain in hospital. This came after she underwent surgery for prostate cancer last December, which was kept secret even from President Joe Biden. The initial hospitalization raised controversy in the U.S., and Austin was later re-hospitalized on January 1 due to complications. Her duties have been transferred to her deputy, Kathleen Hicks, during her absence.
