The Associated Press has this story about the controversy about where prison population should count in Mississippi for redistricting purposes.  It contains this error:

"And that opens the door for possible challenges of redistricting plans, which require approval of the U.S. Justice Department."

This is not accurate.   Redistricting plans require approval of the DOJ, or, approval of the federal district court in D.C.  As has been widely reported, states should go straight to court instead of to the DOJ.
