There is evidence. It's just not on Breitbart. Russian citizens hacked the DNC email accounts (fact) and sent them to wikileaks (fact). They did not hack the RNC emails (fact) and it's not because they didn't find anything. US Intelligence agencies have claimed that an analysis of the hacks has indicated that it was directed by the Russian government (fact). Now, as to whether it was done with the intent to "help trump get elected" is conjecture. It certainly hurt the Democrats and Clinton. It is nice to see the Democrats getting exposed for the things they did regarding Bernie Sanders. It would have been less suspicious of the Russians if they had hacked Democrat AND Republican emails because I'm sure they are just as scandalous.
