It's not contentious... Mueller report lists collusion and the summary that the campaign "expected to benefit from stolen information"
Have a cite? Of course not. Leftards lie and love to be lied to. What benefits did the Clinton campaign expect to receive from the fraudulent Steele Dossier that they paid for and then leaked to the DOJ and FBI so they could get criminally fraudulent FISA warrants. So, a moron leftard wants to invent a crime and happily ignores the real criminal behavior.
