Gov. Bobby Jindal filed a lawsuit Wednesday against the Obama administration, accusing it of illegally manipulating federal grant money and regulations to force states to adopt the Common Core education standards. The Department of Education has used a $4.3 billion grant program and federal policy waivers to encourage states to adopt uniform education standards and testing. The legal challenge puts Jindal, who is considering a 2016 presidential bid, at the forefront of a dispute between conservatives and Obama, bolstering the governor's profile.
