DOJ has taken LA to court because it contends the school voucher program impedes desegregation.

LA contends otherwise.

The filing on Thursday was in response to the DOJís request for information on the program. A hearing on the case is set for Nov. 22.

President Obama traveled to Louisiana on Friday to tour the Port of New Orleans. Louisiana Gov. Bobby Jindal said he invited the president to visit with children and parents participating in the voucher program, but Obama did not accept the offer.
