The Senate Intelligence Committee has unanimously endorsed the U.S. intelligence community’s conclusion that Russia conducted a sweeping and unprecedented campaign to interfere in the 2016 presidential election.

The heavily-redacted report, based on a three-year investigation, builds on a committee finding nearly two years ago that the January 2017 intelligence community assessment (ICA) on Russia was sound. The spy agencies also found that Russia sought to shake faith in American democracy, denigrate then-candidate Hillary Clinton and boost her rival Donald Trump.

The report, while not unexpected, is nonetheless a milestone — the first extensive bipartisan congressional affirmation of the intelligence agencies’ conclusion, which continues to be at odds with President Trump’s oft-stated doubts about Russia’s role in the 2016 race.
