The "Russia Investigation" refers to a series of inquiries into potential interference by Russia in the 2016 United States presidential election. The investigation aimed to determine whether there were any connections between Donald Trump's campaign and Russian officials, as well as to assess the impact of Russian activities on the election process. The investigation was led by Robert Mueller, who served as the special counsel. It involved extensive interviews, document reviews, and the examination of various communications. The findings were detailed in a report released in 2019, which concluded that while there was no conclusive evidence of a conspiracy, Russia did engage in efforts to influence the election.
