(Washington, DC) -- First Lady Michelle Obama is going head-to-head with House Republicans and food industry leaders seeking to scale back school lunch standards. She's expected to deliver remarks against a bill that would allow school districts to opt out of federal rules that limit sodium and require more fresh fruits and vegetables in lunches. That measure is being pushed by the food industry and has the backing of House Republicans. Today's speech will be a rare move for the First Lady, who typically steers clear of wading into legislative battles. The current rules were put into place in 2010 when Congress passed the Healthy Hunger-Free Kids Act.
