WASHINGTON, DCIn the first-ever appointment of its kind, President Clinton named Michael Barnett, a 15-year-old Bethesda, MD, boy who has Down Syndrome, the U.S. Very Special Secretary of Defense Monday. 'Michael is very special. He is fun, loves to laugh and is always smiling,' Clinton said. When informed of his appointment, Barnett waved a pen and said, 'I'm a special boy!' then mistakenly signed an order for the Marines to seize all private property in the U.S. Clinton quickly nullified the order, saying, 'Michael is very special, and I know he will be trying very hard. And that's what's important.'
