Court documents recently made public reveal that federal investigators given a sweeping mandate by the FBI to uncover organized crime and political corruption handed out $1,088,736 in cash and checks over the course of about five years. Some of that money went to political heavyweights, including Mayor Ed Lee.The slush fund, which stemmed from the probe into state senator Leland Yee and his confidants Keith and Brandon Jackson, was used to bribe San Francisco officials, buy guns, ammo, wine, and host parties. Leland Yee, Chinatown association leader Raymond “Shrimp Boy” Chow — an ex-con charged with money laundering — and 27 other defendants were caught up in a multi-year federal inquiry after Yee was accused of taking bribes in exchange for political favors. Yee also allegedly orchestrated a multi-million dollar arms deal that eventually fell through.In addition to bribes and entertainment, the slush fund also included a $500 check (now archived in federal court documents) that an undercover federal agent wrote to Mayor Lee’s bid for office in 2011. As thereported, that $500 was allegedly attached to $20,000 in illegal campaign contributions, which was spread across multiple straw donors.The Mayor’s campaign did not return’s request for comment, although Kevin Heneghan, the Mayor's former campaign treasurer and current president of the California Political Attorneys Association, issued this statement: "Mayor Lee's campaign is committed to following the letter and spirit of all campaign finance laws. If and when the Mayor’s campaign receives specific information from the government about any questionable contributions, we will take immediate and appropriate actions."Federal investigators say they recovered the cash in the slush fund when they raided the defendants last March.Mayor Lee wasn’t the only beneficiary of the FBI’s slush money. Defendant Keith Jackson, a former school board president turned political consultant, accepted more than $50,000, according to an FBI report made public in one of Jackson’s court filings. And Nazly Mohajer, a former Human Rights Commissioner, also cashed two $5,000 checks from the same FBI agent less than a month after the $500 check cleared the Lee campaign.could not reach Mohajer by publication time.A court filing Tuesday evening from Keith Jackson’s attorneys is the first time Mohajer has been publicly named in court documents, although she has not been charged publicly with any crimes. But she may be tied to the investigation: several months ago theclaimed Mohajer hosted the fundraiser during which Mayor Lee took the FBI’s money — a meeting that prosecutors say Keith Jackson arrangedThe money earmarked for Jackson was explicitly intended to encourage the man to commit federal offenses, his lawyers say. In pursuit of that objective, federal agents treated Jackson to parties, posh restaurants, and clubs: Umbria on second street, Stanford Park Hotel, and the View Lounge.Jackson’s attorneys also claim the feds launched an internal investigation into the undercover agent known as UCE 4773 — a.k.a. Michael Anthony King — an investigation that is still ongoing, and that for unknown reasons the agent is no longer employed by the government, Jackson’s lawyers wrote in a filing.The documents filed by Jackson’s attorneys are also the first look the public has had at the massive trove of audio files, video — including aerial surveillance — and seized documents since the feds announced the indictment in March 2014. That’s because federal magistrate Charles Breyer agreed to gag all of the evidence before the government produced it.That evidence, Chow’s attorneys have argued, contains information that’s vital to the public’s interest, because of the investigation’s sweeping mandate to uncover corruption using a handful of disguised federal agents.Since the indictment announcement, we’ve learned that Joe Montana , Supervisors London Breed and Malia Cohen Suge Knight, Katt Williams, and Too $hort have all been touched by the probe — although none has been charged with any crimes or implicated in the alleged racketeering conspiracies.At the moment, the case has been split into two trials: the first will center around Leland Yee’s alleged international arms trafficking deal and public corruption. That group of defendants is scheduled to go to trial in August. But recently, Brandon Jackson’s attorneys asked the judge to continue the trial until mid-2016 because there is so much evidence — several terabytes, with more coming — and it’s impossible for a staff of four to sift through it quickly enough.Chow and the defendants tied to the alleged criminal element of the Ghee Kung Tong do not have a trial date set. That’s something that Chow has told me on several occasions he doesn’t believe is fair. He’s eager to go to trial, he told me from jail.Read some of the court docs below.
