A federal judge on Monday denied former New Orleans Mayor Ray Nagin’s appeal of his conviction and 10-year sentence for corruption charges.

U.S. District Judge Jane Triche Milazzo said that none of a litany of complaints Nagin raised about prosecutors and his own defense attorney, in a brief he wrote from a federal prison camp in Texas, justified overturning the first conviction of a New Orleans mayor for public corruption.

The 63-year-old Nagin is due to stay behind bars until May 25, 2023, according to a U.S. Bureau of Prisons inmate database.

A jury convicted the two-term mayor on a raft of charges for illegal doings with city vendors at a trial in 2014, completing a stunning fall for the former corporate executive hailed as a reform candidate during his first run for office.

Nagin’s star had dimmed, over his handling of Hurricane Katrina, by the time he was accused of taking bribes from city contractors and using his position to win a granite installation contract from Home Depot in 2013.

Nagin, who also lost an earlier appeal of his conviction, acted as his own lawyer in 2017 when he filed an appeal arguing that a U.S. Supreme Court decision overturning the corruption case against former Virginia Gov. Bob McDonnell should also apply to him.

The high court dramatically narrowed the scope of which “official acts” could be counted as parts of illegal quid pro quos. But Milazzo said this week that the ruling in McDonnell’s case did not apply to Nagin, since the ex-mayor was convicted under a different law.

Meanwhile, the judge also swatted away Nagin's claim that prosecutors failed to notify his defense about a separate case involving Covington businessman Frank Fradella, the star witness against him.

Fradella said he repeatedly gave Nagin big payouts in hopes of getting a major redevelopment project. He was sentenced to a year in prison for bribing the mayor in 2015.

In 2017, Fradella was accused of a separate scheme in Florida involving money laundering. Nagin said the prosecution should have alerted his defense team about that case so they could use it to attack Fradella’s credibility.

There was just one small problem with that part of Nagin’s appeal, Milazzo said. Fradella’s alleged Florida scheme did not begin until October 2014, months after Nagin’s trial.

“The government could not have disclosed evidence of alleged criminal activity involving Fradella that did not even begin until after Nagin’s trial and sentencing,” Milazzo said.

The judge also shot down objections from Nagin that his lead defense counsel, Robert Jenkins, bungled his closing argument and failed to prepare the former mayor to take the stand, among other shortcomings.

Nagin also claimed that Jenkins failed to alert a judge of mid-trial intimidation from the prosecution.

"You were pretty hard on my FBI witness related to Nagin's taxes, so just how are YOUR taxes?" Nagin claimed an unnamed prosecutor said. After that, he said, Jenkins seemed "a bit shook up."

In their response to Nagin's appeal, prosecutors said that nothing of the sort happened. The defense lawyer agreed that no intimidation had occurred, they said.

Milazzo was unswayed by any of the ex-mayor's arguments.

“Ultimately, Nagin’s trial team — including Jenkins — introduced exhibits, called witnesses, cross-examined government witnesses, and delivered compelling arguments throughout a trial that lasted more than a week,” she wrote in her decision. “Despite these efforts, the jury convicted Nagin on numerous counts in the face of an abundance of evidence suggesting he was guilty as charged.”
