Those wondering why the Department of Justice has refused to go after Jon Corzine for the vaporization of $1.6 billion in MF Global client funds need look no further than the documents uncovered by the Government Accountability Institute that reveal that the now-defunct MF Global was a client of Attorney General Eric Holder and Assistant Attorney General Lanny Breuer’s former law firm, Covington & Burling.

There’s more.

Records also reveal that MF Global’s trustee for the Chapter 11 bankruptcy retained as its general bankruptcy counsel Morrison & Foerester–the very law firm from which Associate Attorney General Tony West came to DOJ.

And more.

As Government Accountability Institute President Peter Schweizer explains in the Washington Times Thursday, the trustee overseeing MF Global’s bankruptcy is former FBI Director Louis Freeh. At Holder’s Senate confirmation hearing Freeh served as a character witness for Holder and revealed that Holder had previously worked for Freeh. “As general counsel,” Freeh said, “I could have engaged any lawyer in America to represent our bank. I chose Eric.”

Until now, the conventional wisdom for why Holder wouldn’t throw the book at Corzine was that Corzine is an Obama campaign bundler. Indeed, as Breitbart News reported, four of the top officials at the Department of Justice–Eric Holder, Thomas Perrelli, Karol Mason, and Tony West–were also big money bundlers for Obama.

But the newly understood crony connections reveal conflicts of interest that extend well beyond mere political support for a common candidate–they go to a tangle of prior business dealings that further underscore the need for a special prosecutor in the Corzine case.

At least 65 members of Congress have already signed a letter to Attorney General Eric Holder requesting that he appoint a special prosecutor to investigate MF Global’s collapse and the loss of $1.6 billion in customer money. What’s more, even progressives have begun to wonder whether Holder’s Covington & Burling connection explains why the Department of Justice has not charged, prosecuted, or jailed a single Wall Street executive after the biggest financial collapse in American history.

As Richard Eskow of the Huffington Post recently wrote:

More and more Washington insiders are asking a question that was considered off-limits in the nation’s capital just a few months ago: Who, exactly, is Attorney General Eric Holder representing? As scandal after scandal erupts on Wall Street, involving everything from global lending manipulation to cocaine and prostitution, more and more people are worrying about Holder’s seeming inaction — or worse — in the face of mounting evidence.

This isn’t going away.

Both the left and the right are onto Holder’s Wall Street head fake. With the revelation of the new crony connections, the time for Eric Holder to appoint a special prosecutor in the Corzine/MF Global case is now.
