President Trump claimed in a tweet over the weekend that the controversial Nunes memo “totally vindicates” him, clearing him of the cloud of the Russia investigation that has hung over his administration for a year now.

Nothing could be further from the truth.

In fact, if anything, the Mueller investigation appears to have been picking up steam in the past three weeks—and homing in on a series of targets.

Last summer, I wrote an analysis exploring the “known unknowns” of the Russia investigation—unanswered but knowable questions regarding Mueller’s probe. Today, given a week that saw immense sturm und drang over Devin Nunes’ memo—a document that seems purposefully designed to obfuscate and muddy the waters around Mueller’s investigation—it seems worth asking the opposite question: What are the known knowns of the Mueller investigation, and where might it be heading?

The first thing we know is that we know it is large.

We speak about the “Mueller probe” as a single entity, but it’s important to understand that there are no fewer than five (known) separate investigations under the broad umbrella of the special counsel’s office—some threads of these investigations may overlap or intersect, some may be completely free-standing, and some potential targets may be part of multiple threads. But it’s important to understand the different “buckets” of Mueller’s probe.

As special counsel, Mueller has broad authority to investigate “any links and/or coordination between the Russian government and individuals associated with the campaign of President Donald Trump,” as well as “any matters that arose or may arise directly from the investigation,” a catch-all phrase that allows him to pursue other criminality he may stumble across in the course of the investigation. As the acting attorney general overseeing Mueller, Rod Rosenstein has the ability to grant Mueller the ability to expand his investigation as necessary and has been briefed regularly on how the work is unfolding. Yet even without being privy to those conversations, we have a good sense of the purview of his investigation.

Right now, we know it involves at least five separate investigative angles:

1. Preexisting Business Deals and Money Laundering. Business dealings and money laundering related to Trump campaign staff, including former campaign chairman Paul Manafort and former campaign aide Rick Gates, are a major target of the inquiry. While this phase of the investigation has already led to the indictment of Gates and Manafort, it almost certainly will continue to bear further fruit. Gates appears to be heading toward a plea deal with Mueller, and there is expected to be a so-called “superseding” indictment that may add to or refine the existing charges. Such indictments are common in federal prosecutions, particularly in complicated financial cases where additional evidence may surface. Mueller’s team is believed to have amassed more than 400,000 documents in this part of the investigation alone. There have also been reports—largely advanced through intriguing reporting by Buzzfeed—about suspicious payments flagged by Citibank that passed through the accounts of the Russian embassy in the United States, including an abnormal attempted $150,000 cash withdrawal by the embassy just days after the election.

2. Russian Information Operations. When we speak in shorthand about the “hacking of the election,” we are actually talking about unique and distinct efforts, with varying degrees of coordination, by different entities associated with the Russian government. One of these is the “information operations” (bots and trolls) that swirled around the 2016 election, focused on social media platforms like Facebook and Twitter, possibly with the coordination or involvement of the Trump campaign’s data team, Cambridge Analytica.

Presumably these so-called active measures were conducted by or with the coordination of what’s known colloquially as the Russian troll factory, the Internet Research Agency, in St. Petersburg. The extent to which these social media efforts impacted the outcome of the election remains an open question, but according to Bloomberg these social media sites are a “red hot” focus of Mueller’s team, and he obtained search warrants to examine the records of companies like Facebook. In recent weeks, social media platforms like Facebook and Twitter have begun working to notify more than a million users they suspect interacted with Russian trolls and propaganda.
