Rachel Maddow notes an particularly specific warning from the director of the ODNI's National Counterintelligence and Security Center that "pro-Russia Ukrainian parliamentarian Andriy Derkach is spreading claims about corruption" as part of Russia's efforts to manipulate the 2020 U.S. election against Joe Biden and in support of Donald Trump. Derkach has not only been using Rudy Giuliani to spread his claims, but Republican senators Ron Johnson and Chuck Grassley have also been receptive to the Russian tactic. Aired on 8/7/2020
