The Mueller Report is a document produced by Special Counsel Robert Mueller after an investigation into Russian interference in the 2016 U.S. presidential election. It examines potential connections between the Trump campaign and Russian operatives, as well as possible obstruction of justice by President Donald Trump. Released in April 2019, the report is divided into two volumes. The first volume focuses on the Russian interference and the second addresses obstruction of justice. While the report did not establish that the Trump campaign conspired with Russia, it did outline several instances of potential obstruction by the president.
