‘A lot of the criticism seems to be driven by the notion that the FBI’s investigation was, and is, an effort to undermine or discredit President Trump. That assumption is wrong. The FBI’s investigation must be viewed in the context of the bureau’s decades-long effort to detect, disrupt and defeat the intelligence activities of the governments of the Soviet Union and later the Russian Federation that are contrary to the fundamental and long-term interests of the United States. The FBI’s counterintelligence investigation regarding the 2016 campaign fundamentally was not about Donald Trump but was about Russia. Full stop. It was always about Russia. It was about what Russia was, and is, doing and planning. Of course, if that investigation revealed that anyone—Russian or American—committed crimes in connection with Russian intelligence activities or unlawfully interfered with the investigation, the FBI has an obligation under the law to investigate such crimes and to seek to bring those responsible to justice. The FBI’s enduring counterintelligence mission is the reason the Russia investigation will, and should, continue—no matter who is fired, pardoned or impeached.’ (James Baker, formerly F!)BI General Counsel)

Put simply, I don’t believe the FBI, having an open counterintelligence investigation, simply opened a new criminal investigation of obstruction in the wake of the Comey firing. I think there likely was—and still is—one umbrella investigation with a number of different threads. That one investigation was (and is) about Russia. And it had (and still has), as a subsidiary matter, a number of subsidiary files open about people on the U.S. side who had links to Russian government activity. Each of these files had (and still has) all of the counterintelligence and criminal tools available to the U.S. government at its disposal.

So when the president sought to impair the investigation, having declared both in the draft letter dismissing Comey and to Lester Holt that his action was connected in some way to the Russia investigation, that raised both potential criminal questions and major counterintelligence questions—questions that could only have been reinforced when Trump later announced to senior Russian government officials that he had relieved pressure on himself by acting as he did. It did so both because it threatened the investigation itself and because it fit directly into a pattern of interface between Trump campaign officials and Russian government actors that they were already investigating.
