A three-day trial in a lawsuit challenging Gov. Bobby Jindal's voucher program as unconstitutional is wrapping up. Baton Rouge Judge Tim Kelley asked lawyers to give their closing arguments Friday. It was unclear if he would rule immediately after their arguments or request additional information in the form of post-trial legal filings. Teacher unions and school boards are seeking to shut down the vouchers and other changes that would funnel more money away from traditional public schools. They say it's illegal to pay for vouchers to private schools through the public school funding formula. They also claim lawmakers didn't follow the proper process. The state education department and the Board of Elementary and Secondary Education say the programs were funded and created in line with the constitution.
