"Russian Roulette" by Isikoff and Corn, investigative reporting on the Russians activities in the U.S. 2016 elections. From other sources it seems this goes well back in modern history, and the Russians approached Adlai Stevenson, JFK, and Lyndon Johnson offering support, were firmly rebuffed in all instances, but still were active meddling. This is just what they do. They don't care which party, they want to get into the process. A number of other countries do this too, as has the U.S. in other countries.
