Ann Veneman was nominated Wednesday by President-elect George W. Bush to serve as US Secretary of Agriculture. She would be the first woman to hold the post. "I want to promote policies that will help all of our farmers reap a bountiful harvest for years to come," she said. Veneman, 51, has held a variety of agriculture-related posts since 1986. She was the first woman to serve as director of the California Department of Food and Agriculture, 1996-'98.
