“This office will continue its history of investigating and prosecuting public corruption” said U.S. Attorney Dana J. Boente in a statement.  “This is an important part of the office’s mission to serve the citizens of the Eastern District of Louisiana and make certain they have honest public officials.”

According to the U.S. Attorney for Lousiana, if Nagin is convicted on all counts he could face decades in federal prision and extensive fines. 

Nagin tangled frequently with former President George W. Bush during the days and months after the storm, repeatedly criticizing the president's federal response. In a book released in 2011, Nagin suggested there was a racial component to the president's response.

"I'm not telling you that President Bush was a racist or what have you. But I think race and class and politics played in just about every aspect of this disaster," Nagin said in a interview with NBC's "Today Show."
