There are print versions of the April 18, 2019, Mueller Report (“Report on the Investigation into Russian Interference in the 2016 Presidential Election“) in the marketplace (although one publication has virtually unreadable tiny print) and there are multiple online versions so take your pick.
Many public libraries have the e-book and some may have the print.
Link to a PDF copy of the report from, among other places, the Wikipedia Mueller Report article, e.g. from the “External links” section of the article.
