Coca-Cola has hired the lobbying firm Holland & Knight to ward off Federal restrictions on vending machines in schools, reports O'Dwyer's PR Daily. Vermont Sen. Patrick Leahy has introduced a bill that would prohibit schools participating in the national school lunch program from selling soda and candy. Leahy was critical of soda manufacturers for pushing their products at children in a "captive market." He also cited a study linking soda consumption to child obesity and diabetes.
