THE NATION: These Questions for Mueller Show Why Russiagate Was Never the Answer.

“For two years, Democrats have waited on Robert Mueller to deliver a death blow to the Trump presidency,” The New York Times observed on July 20. “On Wednesday, in back-to-back hearings with the former special counsel, that wish could face its final make-or-break moment.” The very fact that Democrats had to subpoena Mueller in order to create this final moment should in fact be the final reminder of what a mistake it was for Democrats to have waited on him. If Mueller had incriminating information yet to share, or had been stymied from doing his work, or if Attorney General William Barr had somehow misrepresented his findings, then it stands to reason that Mueller would be welcoming the opportunity to appear before Congress, not resisting it. The reality is that Mueller’s investigation did not indict anyone on the Trump campaign for collusion with Russia, or even for anything related to the 2016 election. Mueller’s report found no evidence of a Trump-Russia conspiracy, and even undermined the case for it.

That said, there are unresolved matters that Mueller’s testimony could help clarify. Mueller claimed to have established that the Russian government conducted “a sweeping and systematic” interference campaign in order to elect Trump, yet the contents of his report don’t support that allegation. The Mueller report repeatedly excludes countervailing information in order to suggest, misleadingly, that the Trump campaign had suspect “links” and “ties” to people connected with Russia. And Mueller and other intelligence officials involved in the Russia probe made questionable investigative decisions that are worthy of scrutiny. To address these issues, here are some questions that Mueller could be asked.

The entire Russian collusion/Mueller operation seems to have been a house of cards premised on the belief that Trump would fold in the face of sufficient media pressure. When he didn’t, it failed. Now comes finding out who did what, and holding them responsible.
