Did Rod Rosenstein concoct a scheme to let Uranium One's briber, Vadim Mirkerin, off the hook?  Andrew McCarthy seems to think so:

Around the time President Obama came to power, the Russian official in charge of Tenam [parent of Rosatom] was Vadim Mikerin. The Obama administration reportedly issued a visa for Mikerin in 2010, but a racketeering investigation led by the FBI determined that he was already operating here in 2009.  As Tenam's general director, Mikerin was responsible for arranging and managing Rosatom/Tenex's contracts with American uranium purchasers. ...

To further the Kremlin's push for nuclear-energy expansion, he had been seeking to retain a lobbyist – from whom he planned to extort kickbacks, just as he did with the U.S. energy companies. With the help of an associate connected to Russian organized-crime groups, Mikerin found his lobbyist. The man's name has not been disclosed, but we know he is now represented by Victoria Toensing, a well-respected Washington lawyer, formerly a federal prosecutor and counsel to the Senate Intelligence Committee. ...

At the time this unidentified man became an informant, the FBI was led by director Robert Mueller, who is now the special counsel investigating whether Trump colluded with Russia. The investigation was centered in Maryland (Tenam's home base). There, the U.S. attorney was Obama appointee Rod Rosenstein – now President Trump's deputy attorney general, and the man who appointed Mueller as special counsel to investigate Trump. ...

Even though the FBI had an informant collecting damning information, and had a prosecutable case against Mikerin by early 2010, the extortion racket against American energy companies was permitted to continue into the summer of 2014. It was only then that, finally, Mikerin and his confederates were arrested.

Why then? This is not rocket science. In March 2014, Russia annexed Crimea. Putin also began massing forces on the Ukrainian border, coordinating and conducting attacks, ultimately taking control of territory. Clearly, the pie-in-the-sky Obama reset was dead. Furthermore, the prosecution of Mikerin's racketeering scheme had been so delayed that the Justice Department risked losing the ability to charge the 2009 felonies because of the five-year statute of limitations on most federal crimes.

Still, a lid needed to be kept on the case. It would have made for an epic Obama administration scandal, and a body blow to Hillary Clinton's presidential hopes, if in the midst of Russia's 2014 aggression, public attention had been drawn to the failure, four years earlier, to prosecute a national-security case in order to protect Russia's takeover of U.S. nuclear assets.

The Obama administration needed to make this case go away – without a public trial if at all possible. Think about this: The investigation of Russian racketeering in the American energy sector was the kind of spectacular success over which the FBI and Justice Department typically do a bells-n-whistles victory lap – the big self-congratulatory press conference followed by the media-intensive prosecutions . . . and, of course, more press conferences.

Here ... crickets.

As the Hill reports, the Justice Department and FBI had little to say when Mikerin and his co-conspirators were arrested. They quietly negotiated guilty pleas that were announced with no fanfare just before Labor Day.

It was arranged that Mikerin would be sentenced just before Christmas. All under the radar.

How desperate was the Obama Justice Department to plead the case out? Here, Rosenstein and Holder will have some explaining to do.

Mikerin was arrested on a complaint describing a racketeering scheme that stretched back to 2004 and included extortion, fraud, and money laundering. Yet he was permitted to plead guilty to a single count of money-laundering conspiracy.

Except it was not really money-laundering conspiracy.

Under federal law, that crime (at section 1956 of the penal code) carries a penalty of up to 20 years' imprisonment – not only for conspiracy but for each act of money laundering. But Mikerin was not made to plead guilty to this charge. He was permitted to plead guilty to an offense charged under the catch-all federal conspiracy provision (section 371) that criminalizes agreements to commit any crime against the United States. Section 371 prescribes a sentence of zero to five years' imprisonment.

The Justice Department instructs prosecutors that when Congress has given a federal offense its own conspiracy provision with a heightened punishment (as it has for money laundering, racketeering, narcotics trafficking, and other serious crimes), they may not charge a section 371 conspiracy. Section 371 is for less serious conspiracy cases. Using it for money laundering – which caps the sentence way below Congress's intent for that behavior – subverts federal law and signals to the court that the prosecutor does not regard the offense as major. Yet, that is exactly what Rosenstein's office did, in a plea agreement his prosecutors co-signed with attorneys from the Justice Department's Fraud Section.
