I'm starting to wonder if Trump's own people are trying to sabotage him.  Whoever fed him the breitbart article with this claim must have known that was was going to react to it.  By tweeting what he did, he opened himself up to being caught in a lie in a very public and high profile way.  If they don't find any evidence of any Obama-ordered wiretap (and they probably won't), that is the best-case scenario.  The worst-case scenario is that the investigation forces the wiretaps and anything incriminating on them into discovery.  Stay tuned...
