Robert Mueller’s effort to stand outside partisan politics in his investigation of President Donald Trump will no doubt follow him into the pages of American history. But for now there are still some questions that he needs to answer, despite his reluctance to say anything more than is contained in his 448-page report.
Unfortunately, it’s far from clear that members of the House Intelligence and Judiciary committees will ask the right questions when Mueller testifies before them, under subpoena, on July 17. With so much attention focused on the hearing, congress members from both parties won’t be able to resist wasting the public’s time on self-justifying statements rather than questions.
Mueller has essentially left it to Congress to determine whether Trump violated the law by obstructing justice, and if so, whether the president’s conduct was so egregious that it warrants impeachment. But he needs to explain, more clearly than his report does, why Trump would want to block an investigation into whether he or others in his campaign criminally conspired with Russian authorities in their effort to influence the 2016 presidential campaign. After all, Mueller found that no Americans entered into that conspiracy: AKA “no collusion.”
