The indictment also stands as an implicit rebuke to President Trump, who has repeatedly refused to acknowledge the Russian role in the election, saying many actors may have been involved. He has also rejected the idea that any interference might have aided him. His rejection puts him at odds with the entire American intelligence establishment, which has concluded that Russia interfered. On Tuesday, top officials, many of them Trump appointees, reaffirmed that stance and said Russia would also seek to meddle in the 2018 election.

The allegations contained in this indictment, returned by a federal grand jury in Washington, D.C., do not reach the most politically contentious questions in Mueller’s view. They do not concern the hacking of emails from the Democratic National Committee, Clinton campaign officials, and the Republican National Committee. They don’t address questions of collusion between the Trump campaign and Russia; indeed, this indictment states that Russians had some contact with Trump officials, but Deputy Attorney General Rod Rosenstein said Friday that “there is no allegation in this indictment that any American was a knowing participant” in law-breaking. He added, “There is no allegation in the indictment that the charge conduct altered the outcome of the 2016 election.” Neither does this indictment touch on whether Trump obstructed justice.

Nonetheless, the indictment makes it difficult for Trump to continue to claim that Russia did not interfere in the election. It states:

Defendant ORGANIZATION had a strategic goal to sow discord in the U.S. political system, including the 2016 U.S. presidential election. Defendants posted derogatory information about a number of candidates, and by early to mid-2016, Defendants’ operations included supporting the presidential campaign of then-candidate Donald J. Trump (“Trump Campaign”) and disparaging Hillary Clinton.

When the intelligence community has previously leveled that charge in the past, it has offered only vague evidence, basically asking for the benefit of the doubt. That allowed skeptics of the intelligence agencies, as well as Trump and his allies, to cast doubt on the claims. Friday’s indictment contains far more detail, and while its contents are allegations, not claims proven in a court, they are bolstered by extensive documentary evidence, including emails and messages. Much of the material has been reported in various news outlets, but the indictment puts it all in one place for the first time.

Here’s what the indictment lays out.

The Russian effort to meddle in the election began way back in 2014, long before anyone viewed Trump as a serious candidate for the presidency, much less a likely nominee. The goal was simply to create division and chaos by exploiting existing cleavages in American society—or as the indictment puts it, operators were instructed to create “political intensity through supporting radical groups, users dissatisfied with [the] social and economic situation and oppositional social movements.”
