Toby Cosgrove, the head of the prestigious Cleveland Clinic who the White House had considered nominating to lead the troubled Department of Veterans Affairs, said on Saturday he had withdrawn from consideration for that position. Cosgrove, 73, a Vietnam veteran and surgeon, was in the running to replace former VA Secretary Eric Shinseki, who resigned on May 30 amid a political firestorm over widespread delays in veterans' medical care. Deputy Veterans Affairs Secretary Sloan Gibson has been leading the agency while President Barack Obama looks for a permanent replacement. Last week, Cosgrove was said to be under consideration.
