after tests on 'emergent bladder issues' as he passes duties to his deputy for second time in a month following his prostate cancer surgery

Lloyd Austin has been admitted to a critical care unit at Walter Reed Medical Center 'for supportive care and close monitoring' after he was hospitalized for 'symptoms suggesting an emergent bladder issue.'

The Defense Secretary, 70, was transported to military hospital after the symptoms emerged Sunday afternoon.

According to a hospital official, Austin was admitted to the critical care unit 'after a series of tests and evaluations.'

'At this time, it is not clear how long Secretary Austin will remain hospitalized. The current bladder issue is not expected to change his anticipated full recovery. His cancer prognosis remains excellent,' Dr. John Maddox said in a statement.
