Bernie Madoff said he does not need "credit" for helping recover money for victims of his Ponzi scheme, he just wished court-appointed trustee Irving Picard would tell the truth about what Madoff has claimed is his "instrumental" role in the process.
Madoff sent yet another e-mail to me this week, after we reported on the flurry of e-mails he sent last week attacking Picard.
The dustup follows our exclusive interview with Picard and his chief counsel David Sheehan in which Picard said Madoff has "not been helpful" in the recovery of more than $9 billion.

"I am frustrated with both of these attorneys constantly making claims and statements that are false, and nobody in the media challenging them to present the evidence they claim they have," Madoff wrote in his latest message from the federal prison in North Carolina where he is serving a 150-year sentence.
Picard and Sheehan said Madoff provided no new information when they visited him twice in prison, and while he has subsequently offered assistance, nothing of substance has materialized.
Madoff claimed he "pressured the complicit parties to settle" with Picard, and last week said he wished he had gone to trial rather than pleading guilty, so Picard "would have been required to provide the evidence he claims he has."

"As remorseful as I am for the pain and suffering I have shamefully caused, I take some comfort in the fact that my assistance will in fact accomplish what I have originally claimed, that with my assistance all of my customers will recover their original investment principal," Madoff wrote last week.

But in his latest e-mail, he said that does not mean he wants any "credit" for his efforts.
"We stand by our statement that Madoff has been of no assistance to us," said Amanda Remus, a spokesperson for Picard, Sheehan, and their law firm BakerHostetler.
Here is Madoff's latest message in full:
For those who watched the interview of Picard and Sheehan on CNBC and the remark of the host that I was unhappy about not receiving credit for my assistance in obtaining the recoveries. I never said anything about not receiving "credit". My comments were simply stating that I am frustrated with both of these attorneys constantly making claims and statements that are false, and nobody in the media challenging them to present the evidence they claim they have. I would remind you all, that my statement at the start, that" I believed I could help in recovering all my investors original investment principal." were met with the accusations of my being "DELUSIONAL".
