Edwards Bunny-ing up before indictment?

Earlier this week, we found out that the Department of Justice has green-lighted a potential prosecution of former Democratic VP nominee John Edwards on corruption charges.  The allegations will apparently include the use of undisclosed cash from deep-pocket donors to hush up an extramarital affair and out-of-wedlock child with campaign worker Rielle Hunter, serious felonies that could bring lengthy prison sentences.  Should the DoJ be concerned that Edwards is meeting with one of his biggest benefactors, Rachel “Bunny” Mellon, as ABC news reports?

Multiple sources at the estate of Rachel “Bunny” Mellon confirm to ABC News that the former North Carolina senator met Mellon today for lunch at her sprawling compound in Northern Virginia. …

Mellon, heir to a banking fortune, donated more than $4 million dollars to political organizations and non-profits tied to Edwards’ 2008 run and also provided more than $700 thousand that prosecutors believe was funneled to the effort to support and seclude Edwards’ mistress, Rielle Hunter.   Mellon’s attorney has described those payments as gifts and has said that Mellon was unaware of how the money was used.

A target of a grand jury probe meets with one of the key figures in the case for a secluded lunch?   Witness tampering is a crime.  Given his current status, however, that might be the least of his worries.

The FBI may want to re-depose Mellon to see what topics of discussion arose.  The DoJ also may want to formalize these charges ASAP before Edwards goes on a “Two Americas” luncheon tour with the rest of their material witnesses.
