Nobody has any evidence? What about the tapes?
There is quite a bit of evidence. The Administration had folks telling you the laptop and emails were "Russian Disinformation", but we have since learned that they are not. So, some of the evidence has been seen by everybody, while some is being held by the FBI, who worked with Twitter to keep the story off the internets during the campaign, this is one reason why folks are not trusting the FBI anymore.
