LLOYD AUSTIN

WASHINGTON — Defense Secretary Lloyd Austin canceled a trip to Brussels for NATO defense talks after being admitted to a military hospital for a second time this year, the Pentagon said on Monday.

Austin, 70, was taken to Walter Reed Military Medical Center on Sunday for “symptoms suggesting an emergent bladder issue.” On Monday, he underwent nonsurgical procedures under general anesthesia to address his bladder issue, the hospital said.
