If you're interested in what may or may not be in the famed Mueller Report, take a look at this piece by William Saletan. He's compiled a list of things that Trump and various supporters are saying is in the report which apparently none of them have seen. You might also want to take a look at the actual memo that Attorney General Barr penned disclosing some of what's in the 300+ page report. Barr's letter is presumably the source of all these claims of what's in the Mueller Report but I don't find most of those claims in the letter…and some of the assertions contradict each other.
Apparently, it's okay to just make up whatever you want and say it's in Mueller's findings so I'll play along. I say that the Mueller Report states unequivocally that Donald Trump and Vladimir Putin repeatedly dressed in women's clothing and toured the Ukraine in dinner theater productions of The Vagina Monologues. I have just as much proof of that as Lindsey Graham has for anything he says is in the report.
