Under RussiaGate (2016), President-elect Donald Trump had been accused of treason "after President Obama announced new sanctions [in late December 2016] against Russia and Trump praised Vladimir Putin's response to the sanctions." (Daily Caller, December 30, 2016, emphasis added)

Former Secretary of Defense and CIA Director Leo Panetta had already intimated prior to the elections that Trump was a threat to national security. 

Even prior to the inauguration of president Trump, the US media in liaison with US intelligence had launched successive waves of smears directed against President-elect Donald Trump.

The objective from the very outset was to discredit president Trump, presenting him as a Manchurian candidate serving the interests of the Kremlin.

RussiaGate 2.0

The RussiaGate objective as formulated in 2016 was: 

"to get rid of a President who intended to normalize relations with Russia, thus curtailing the budget and power of the military/security complex."

(Paul Craig Roberts, emphasis added)

In January 2019, the FBI Russia investigation was quoted by the media as "evidence" that Trump was "wittingly or unwittingly" an agent of the Kremlin.

What is the stance of the FBI today in regard to the candidacy of Donald Trump? The FBI played a key role in sustaining RussiaGate. (P. C Roberts). I should mention that the FBI is also responsible (coincidentally) for the investigation of the attempted assassination of Donald Trump in Pennsylvania.
