dissemination to congress and public. jon: to reiterate we said you don't think that congress will find anything robert mueller didn't already take a look at? tequesta certainly have the ability to conduct an investigation on their own if they choose to do so. what i don't think they can do that was just issue a blanket subpoena to the justice department and say essentially, give me everything you have. they can do it but it will be met with an objection. even if the objection were to be challenged and faced a court proceeding, i imagine that a court will overrule any effort by the congress to obtain that information. jon: robert ray, former whitewater independent counsel. thanks very much. >> you bet. jon: is taking close to two years for special counsel robert mueller to wrap up the investigation. two years of waiting and all the debating. you may have forgotten how it all began. just what brought us to this point? a report on that next.
