I don't think I made a single claim though lol. I literally only asked for some trustworthy sources. And sorry I should have clarified, I meant sources that you find reputable that backs up your claim that intelligence agencies use this Russian interference tactic to hurt democratic front runners.

I do believe that Russians helped Trump in a myriad of ways to get elected. That leads me to believe that Russians would also try to negatively affect Sanders campaign as well. I feel like its inconsistent to believe that Russians are helping Trump but then turn around and say "I dont have enough evidence to believe Russians are interfering with Sanders campaign". If they are helping Trump, why would they not also try to hurt Sanders? Or any other campaign for that matter.
