WASHINGTON, DCT. Eric Mayhew, 36, who began working in the White House kitchen the day President George W. Bush took office, submitted his resignation Monday. 'The noble work of dishwashing preceded my appointment to this job and will continue long after I leave,' Mayhew said. 'It was an honor to serve under the president. I leave my post proudly, knowing the White House flatware is more sanitary today than it was when I began my work here.' Mayhew will maintain his position until Bush appoints a replacement.
