This story discusses issues related to Mayor Nagin’s acceptance of travel.

Now Nagin, whose career was nearly wrecked by Hurricane Katrina 3 1/2 years ago, has seen his approval ratings sink to their lowest level ever, amid anger over the city’s slow recovery and recent ethics questions about his vacations to Jamaica and Hawaii.

Allegations that Nagin didn’t pay for at least part of the trips were raised in a lawsuit over his once highly touted city crime camera system, now known more for cost overruns than catching criminals.
