For the entirety of Trump’s time in office, he has ridiculed the claim that Russia intervened in the 2016 election. He called this the “Russia hoax” and has attempted repeatedly to discredit the government intelligence agencies that reached this conclusion. He portrays himself as the victim of a “deep state” conspiracy to undermine the legitimacy of his election. He even tasked Attorney General William Barr to launch an investigation of the perpetrators behind the “Russia hoax” and to see that they are punished. And he has fired leaders of the intelligence agencies who might resist his views.

The Senate Intelligence Committee, controlled by Republicans, released a report this week supporting the conclusion that Russia did interfere in the 2016 election, specifically to help Trump and hurt Clinton. The committee was unanimous.

The New York Times reported:

A three-year review by the Republican-led Senate Intelligence Committee unanimously found that the intelligence community assessment, pinning blame on Russia and outlining its goals to undercut American democracy, was fundamentally sound and untainted by politics.

“The I.C.A. reflects strong tradecraft, sound analytical reasoning and proper justification of disagreement in the one analytical line where it occurred,” said Senator Richard M. Burr, Republican of North Carolina and the panel’s chairman. “The committee found no reason to dispute the intelligence community’s conclusions.”

The endorsement by Mr. Burr’s committee comes at a key moment for the intelligence agencies. Not only has Mr. Trump moved in recent months to install a loyalist in the top spy position, but Attorney General William P. Barr has also blessed a broad review of possible misconduct by investigators examining the Trump campaign’s contacts with Russia, apparently including work by intelligence officials…

“The case is closed,” said Senator Angus King, independent of Maine. “I don’t know how you could have a much more credible source than a three-year study by a bipartisan committee that came to a unanimous conclusion…”

Senators said their inquiry found that intelligence analysts who worked on the assessment were “under no politically motivated pressure to reach specific conclusions.”

“All analysts expressed that they were free to debate, object to content and assess confidence levels, as is normal and proper for the analytic process,” the report said.
