New Orleans — A federal judge Wednesday delayed for three weeks the arraignment of former New Orleans Mayor Ray Nagin, who was indicted last week on nearly two dozen charges.

U.S. District Judge Ginger Berrigan moved the court date from Jan. 31 to Feb. 20 at 2 p.m., according to records. No reason was given for the delay. Robert Jenkins, Nagin’s attorney, did not return a phone message Wednesday afternoon. Jenkins has said that his client maintains his innocence and that the indictment surprised him since he assumed plea discussions were ongoing.

The 21-count indictment against Nagin included charges of conspiracy, bribery, wire fraud and filing false income tax returns.

Prosecutors allege Nagin accepted more than $200,000 in bribes and other goods— including granite and free trips— from contractors in exchange for helping them to secure work for the city that was worth millions of dollars.
