The following was my own comment made in the comments ection of the article.
Here is the trap Obama has made for himself. Plausible deniability fails as a defense when the administration obstructs senate oversight. If no one can be identified by a showing of evidence, then the Truman doctrine goes into effect. The one that says the buck stops here. He is ultimately responsible. When Obama figures that out, subsequently flinging the doors open to a search of the record he will then have offered proof in open view of obstruction of justice. P.s. Watch Solyndra turn out to be a money laundering scheme for F&F.
