You need the sword of the house subcommittee system to cut through it and investigate Obama’s finances, both campaign and where possible, personal.
Even then the investigation has to begin at square one, a difficult and time consuming process. The general principle is "follow the money," and the main villains will be revealed. The actual actus rea depends on the exact circumstances of the actors involved and precise times. A prediction for you is that John O. Brennan and Analysis corp will come up. 90 Days to go until the American people can take their revenge out on the "Democrats" in the November 2nd mid term elections. Barack Obama has only succeeded in awakening a sleeping giant
Well, that can be said about virtually any conspiracy case. Despite mountains of evidence, even taped conversations, it can be VERY difficult to prove any criminal conspiracy absent the direct testimony of a cooperating indicted (or indicted) co-conspirator.
