Let's not remove the end of that quote so quickly:
"Special counsel Robert Mueller did not find evidence that President Trump's campaign conspired with Russia to influence the 2016 election, according to a summary of findings submitted to Congress by Attorney General William Barr."
I think Attorney General William Barr did not correctly summarize the findings of the Mueller report, and was acting to drive an incorrect narrative.
Given that, I think it's entirely appropriate to also look at the Republican-controlled Senate report that the OP linked, which says it did.
