Attorney General William Barr released Special Counsel Robert Mueller’s long-awaited report on his investigation into Russian interference in the 2016 presidential election on Thursday. Though some of the findings have been redacted, the report will give the public a clearer sense of what the special counsel found—and whether Barr’s short summary, made public in late March, was accurate.

The report covers the special counsel’s investigation into Russian efforts to influence the 2016 election, and details 10 episodes that Mueller’s team examined as part of its inquiry into whether President Donald Trump obstructed justice. Four types of information are redacted in the report, according to Barr: grand-jury material, and details that could jeopardize intelligence sources and methods, ongoing cases, and the privacy of “peripheral third parties.”

Below, the must-read parts of Mueller’s 448-page report:

1. The special counsel’s office explains why it didn’t bring criminal charges related to collusion, and details how some of the individuals it investigated or interviewed lied or deleted communications.

While the investigation identified numerous links between individuals with ties to the Russian government and individuals associated with the Trump Campaign, the evidence was not sufficient to support criminal charges. Among other things, the evidence was not sufficient to charge any Campaign official as an unregistered agent of the Russian government or other Russian principal. And our evidence about the June 9, 2016 meeting [at Trump Tower between Trump campaign officials and a Russian lawyer] and WikiLeaks’s releases of hacked materials was not sufficient to charge a criminal campaign-finance violation. Further, the evidence was not sufficient to charge that any member of the Trump Campaign conspired with representatives of the Russian government to interfere in the 2016 election. [T]he investigation established that several individuals affiliated with the Trump Campaign lied to the Office, and to Congress, about their interactions with Russian-affiliated individuals and related matters. Those lies materially impaired the investigation of Russian election interference. The Office charged some of those lies as violations of the federal false statements statute … The Office learned that some of the individuals we interviewed or whose conduct we investigated—including some associated with the Trump Campaign—deleted relevant communications or communicated during the relevant period using applications that feature encryption or that do not provide for long-term retention of data or communications records. In such cases, the Office was not able to corroborate witness statements through comparison to contemporaneous communications or fully question witnesses about statements that appeared inconsistent with other known facts. Accordingly, while this report embodies factual and legal determinations that the Office believes to be accurate and complete to the greatest extent possible, given these identified gaps, the Office cannot rule out the possibility that the unavailable information would shed additional light on (or cast in a new light) the events described in the report.
