Don't expect much from Robert Mueller's testimony

Former special counsel Robert Mueller will appear before Congress on Wednesday, presenting both Democrats and Republicans with the greatest political opportunity since President Trump was first accused of colluding with Moscow. Or so they think.

Democrats hope to “breathe life” into the Mueller report, as my colleague Byron York wrote, in an attempt to pin Trump with obstruction of justice charges, thereby kick-starting the impeachment process. Republicans, on the other hand, hope to dispel once and for all the notion that there was any seriousness to Mueller’s investigation, portraying Trump as the victim and the corrupt co-conspirators, the media and the government, as the aggressors.
