WASHINGTON, D.C.—Agriculture Secretary Dan Glickman narrowly escaped being hit in the face with a pie by an ani-mal rights activist. The suspect hurled the pie just as Glickman began a speech at the National Nutrition Summit, a two-day conference to discuss hunger and nutrition issues. Glickman ducked but got "tofu cream" all over the back of his suit, according to People for the Ethical Treatment of Animals, which took responsibility for the action.
