U.S. Attorney Jim Letten stepping down

New Orleans, La. - U.S. Attorney Jim Letten is stepping down from his post at the U.S. Attorney's Office effective December 11th.

Letten made announcement at a Thursday morning press conference.

The move comes after multiple scandals have blemished his office.

Letten acknowledged last week that former First Assistant U.S. Attorney Jan Mann used the on-line handle 'Eweman' to make inappropriate posts on Nola.com about ongoing federal cases.

Letten acknowledged that in a letter sent to a federal judge after the judge denied defendants Aaron Broussard and Tom Wilkinson a motion to recuse the U.S. Attorney's office from their public corruption case.

The motion was filed in May after former U.S. Assistant Sal Perricone admitted that he posted remarks about several defendants on Nola.com.

Meantime, Mann started posting comments several months before Perricone resigned.

Mann was also the one who laid out the case against recusing the U.S. Attorey's office from the corruption cases.

Mann was removed as first assistant in his office and is being investigated.

Mayor Mitch Landrieu released a statement saying, "Jim Letten is a friend. He has been a great partner for the City of New Orleans as we fight public corruption and violent street crime. I look forward to working with President Obama and Senator Landrieu so that the next United States Attorney can be an effective prosecutor against public corruption and street crime."

Mr. Dana J. Boente, currently 1st Asst. in eastern Virginia, will take over next week as interim U.S. Attorney for the Eastern District in Louisiana.

Letten says he plans to stay on with the department briefly to help with the transition in leadership.
