According to Wray, Russia is using social media, proxies, state media and online journals to sow “divisiveness and discord” and “primarily to denigrate Vice President Biden and what the Russians see as kind of an anti-Russian establishment.”

Intelligence officials have said they have uncovered evidence that Russia is currently interfering in the election to hurt Biden’s campaign. Separately, some evidence has already emerged about Moscow’s efforts, including Facebook’s announcement earlier this month that a troll group that was part of Russia’s attempt to interfere in the 2016 election is trying to target Americans again.

But while the intelligence community has assessed that China and Iran prefer Trump to lose in November, officials have offered no indication, to date, that either country is acting on that preference in the same way as Russia, according to public statements issued by the intelligence community and sources familiar with the underlying evidence.
