Did Mueller never expect to be called out? Does Mueller realize what this exposure does to his credibility? Or am I even asking the right questions?
Mueller's ever increasingly outrageous behaviors these past weeks (raiding the President's lawyer's office, wiretapping the President's lawyer) were all intended to provoke Trump into firing him. Then Mueller could play the victim and the Dem/GOP uniparty would then call for Trump's impeachment.
Mueller didn't think anyone would actually fight him in court where there would be the requirement of Mueller turning over his evidence (of which he likely has none.)
Mueller wanted this to be a trial by MSM, because exposing the details of his investigation will expose the raw corruption of the FBI's attempt to overturn the U.S. Election results; the largest political crime in U.S. History.
