the Ethics Committee's was not the only investigation into the scandal. There were two other probes at the time that got barely any public attention--both of which largely focused on McCain himself. These were probes into illicit leaks about the proceedings of the Ethics Committee--leaks that repeatedly benefited McCain and hurt his Keating Five colleagues. One of those senators described the leaks at the time as a "violation of ethical behavior at least as serious as anything of which we senators have been accused."
The leaks, if they were coming from a senator, were also illegal. All five senators--including McCain--had testified under oath and under the U.S. penal code that the leaks did not come from their camps. The leaks were also prohibited by rules of the Senate Ethics Committee; according to the rules of the Senate, anyone caught leaking such information could face expulsion from the body. These, then, were not the usual Washington disclosures: Discovered, they could have stopped the career of any Washington politician in his tracks.
The two investigations into the leaks suggested McCain's involvement but were officially inconclusive. New evidence, obtained in recent weeks, again points back to the McCain camp.
