He and his team have now given us the clearest picture yet of the murky events surrounding Trump’s ascension. “The Russian government interfered in the 2016 presidential election in sweeping and systematic fashion,” they wrote. The Trump campaign welcomed this interference, but, we now know, did not assist in it. “Although the investigation established that the Russian government perceived it would benefit from a Trump presidency and worked to secure that outcome, and that the Campaign expected it would benefit electorally from information stolen and released through Russian efforts, the investigation did not establish that members of the Trump campaign conspired or coordinated with the Russian government in its election interference activities.”

Once in office, Trump sought to thwart the investigation into what Russia had done. He believed — correctly, as it happens — that Russia’s actions cast doubt on the legitimacy of his victory. The report says he may also have feared that what appears to be his advance notice of the WikiLeaks dumps of hacked Democratic emails and his campaign’s now infamous Trump Tower meeting with Russian emissaries offering dirt on Hillary Clinton “could be seen as criminal activity by the President, his campaign, or his family.” Further, although “the President publicly stated during and after the election that he had no connection to Russia,” his company was negotiating to build a Trump Tower Moscow throughout most of the campaign, a fact that could have hurt him politically if it got out.

Numerous commentators have said that the report reads like a road map for impeachment, and in a remotely functional country that’s what it would be. Mueller makes it clear that because of the Office of Legal Counsel’s opinion that a sitting president cannot be indicted, “we determined not to apply an approach that could potentially result in a judgment that the President committed crimes.” Instead, the evidence is laid out for congressional action, or even for prosecutors to indict after Trump leaves office.

The test for us now is how much evidence still matters. Before the report came out, William Barr, Trump’s attorney general, created a fog of disinformation around it, blatantly misleading the public about what it contained.

Weeks before anyone else could read the report, he tried to close the door on obstruction, implying falsely that Mueller meant to leave the decision to him. In a news conference on Thursday, Barr repeatedly said that Mueller had found no “collusion” between the Trump campaign and Russia. Mueller, however, never examined the case through the lens of “collusion,” which isn’t a term in criminal law: “In evaluating whether evidence about collective action of multiple individuals constituted a crime, we applied the framework of conspiracy law, not the concept of ‘collusion,’” the report says. Barr claimed that “evidence of non-corrupt motives weighs heavily against any allegation that the President had a corrupt intent to obstruct the investigation.” The report is overstuffed with evidence of corrupt motives.

But most people aren’t going to read the nearly 500-page report. Republicans have already seized on Barr’s words — and on the lack of criminal charges in a document that was never going to contain criminal charges — to claim total vindication for Trump. The president’s manifest disloyalty to the country in trying to halt an investigation into a foreign attack on an American election is, to the right, of no account. Nor are the counterintelligence implications of Mueller’s findings, which aren’t part of the report. In the eyes of the president’s supporters, his campaign did not participate in the criminal conspiracy that helped elect him, so no more needs to be said.

The reaction to the report shows that between the minority of Americans who support Trump and the majority who do not, there may no longer be even the possibility of a shared sense of reality or national purpose. Even as exemplary a figure as Mueller cannot change that.
