Shitty situation that I had nothing to do with...

So I get a phone call today from my Supervisor, asking if I had anything to do with the leak of sensitive information to a reporter who posted the info on the Web. Since I work at a place where information is vital, an ASSUMPTION was made by a person in a high position that since the reporter said they had an "inside source" (it could never be the interns, right?) at the place where I work, and since I was a "friend" of the reporter on Facebook, that I was the source. I have never met the reporter, I just liked his reports that he put out occasionally. Since I recently started working my role I started out in again, the assumption was I might have "overheard" some information, then leaked it to the reporter. Due to this vicious personal attack, I had to close my Twitter account, and weed out certain members of my friends on Facebook, many of whom I became real friends with in person. It really bothers me that I was forced to choose between my job or being a member of this group of friends. I am not sure if the steps I took were enough for the Powers That Be, and I hope they were. If not, then I am very seriously considering going to the press regarding the false accusations that were made. I have made some personal friends off of Twitter too, and many of them were members of the Philadelphia press. I am sure they would be interested in why my account was suddenly shut down when I had 9908 posts on it... So now I have to shut my mouth, (which I did already!) and not piss off the high ups... The worst part of it is all of the high ups know me personally. That is the most painful part of all this. They know me, know my passion for my job and the place where I work, and yet they were coming with pitchforks based on a wild assumption that had NO MERIT whatsoever! This really hurt me, and I don't know how to shrug it off...
