This article in the Northeast Mississippi Daily Journal confirms that Rep. Bennie Thompson submitted to President Obama Christi McCoy as the next U.S. Attorney for the Northern District of Mississippi. McCoy is originally from Booneville and practices in Oxford.
The article mentions Forest attorney Constance Slaughter-Harvey as the potential nominee in the Southern District. That would be interesting, since Slaughter-Harvey is rumored to have removed her name from consideration. More recently, Deborah McDonald of Natchez is rumored to be the leading candidate.
