Congress will have to decide soon whether it wants another food fight with first lady Michelle Obama and the administration over what’'s served in the school lunch line. School food rules pitted Republicans seeking full exemptions for some schools against Obama in 2014, with the first lady declaring she'd fight "to the bitter end" to make sure kids have good nutrition.
