NEW ORLEANS (AP) – A federal judge agreed Thursday to postpone the trial of former New Orleans Mayor Ray Nagin on bribery charges.

Nagin’s trial was scheduled to start Monday, but U.S. District Judge Helen Berrigan delayed it until Jan. 27.

Nagin’s lawyer, Robert Jenkins, asked for more time to prepare. Prosecutors opposed his request for a delay, arguing Jenkins already has had adequate time.

Berrigan, however, noted in her order that prosecutors plan to present a “considerable number of documents” for a case that delves into Nagin’s entire eight-year tenure as mayor.

Nagin, whose second and final term as mayor ended in 2010, was indicted in January on charges that he accepted free trips and more than $200,000 in bribes from contractors in exchange for helping them secure lucrative city contracts.

The case is the centerpiece of a city hall corruption investigation that has already resulted in guilty pleas by two former city officials and two businessmen and a prison sentence for a former city vendor.

Jenkins also had asked Berrigan to throw out Nagin’s indictment, arguing the case has been tainted by the online activities of at least two federal prosecutors who acknowledged posting anonymous comments on a newspaper’s website about cases, judges and politicians, including Nagin. Berrigan rejected that request last week.
