The judge's request for a more thorough investigation is backed up by a watchdog group, the Justice Integrity Project, a group that says it monitors for problems and abuse of power in federal prosecutors' offices.
Justice Integrity Project Executive Director Andrew Kreig tells WWL Morning show host Tommy Tucker he is worried any time the Justice Department is investigating itself.
''You've got a real crisis of confidence here in New Orleans, where people should take the extra step to help resolve the public's concerns,'' said Kreig.

Kreig said he is puzzled that First Assistant U.S. Attorney Jan Mann has not been suspended or fired after her recent admission to anonymously posting online comments. Earlier this year, federal prosecutor Sal Perricone resigned after admitting to anonymously posting online, often about about active federal cases and investigations.
Kreig is worried that an internal investigation could stretch out to months, and is concerned that a long investigation would result in the controversy "blowing over" by the time a conclusion is reached.
He considers internal investigations by the DOJ in such matters "white washes,'' and says an independent investigator is needed.
Although defense attorneys in the Danziger case are calling for dismissal of convictions and new trials, those requests have so far not been granted.
