Brennan charges, "Trump is abetting a Russian covert operation to keep him in office for Moscow's interests, not America's." But congressional representatives, both Democratic and Republican, who heard a briefing by the intelligence community about the 2020 election earlier this month say the case for Russian interference is "overstated."

On February 21, it was leaked to the Washington Post that "U.S. officials," meaning members of the intelligence community, had confidentially briefed Sanders about alleged Russian efforts to help his 2020 presidential campaign.

Special prosecutor Robert Mueller documented how the Russians intervened on Trump's behalf in 2016, while finding no evidence of criminal conspiracy. Mueller did not investigate the Russians' efforts on behalf of Sanders, but the Computational Propaganda Research Project at Oxford University did. In a study of social media generated by the Russia-based Internet Research Agency (IRA), the Oxford analysts found that the IRA initially generated propaganda designed to boost all rivals to Hillary Clinton in 2015. As Trump advanced, they focused almost entirely on motivating Trump supporters and demobilizing black voters. In short, the Russians helped Trump hundreds of thousand times more than they boosted Sanders.
