Ray Nagin, who was the mayor of New Orleans during Hurricane Katrina, has been sentenced to 10 years in prison on a variety of federal corruption charges. From NBC:
Nagin, 58, was convicted on Feb. 12 of accepting more than $500,000 worth of bribes and free trips from contractors in exchange for helping them clinch millions of dollars in city work when he was mayor of New Orleans, both pre- and post-Hurricane Katrina. He was found guilty of 20 out of 21 counts in the indictment. Nagin, a Democrat who was mayor for two terms from 2002 to 2010, denied he took any bribes.
This piece in the New Orleans Times-Picayune documents the specific charges against Nagin—and notes that early in his mayoral career he presented himself as an anti-corruption reformer.
