Durham special counsel investigation

The Durham special counsel investigation (aka Report on Matters Related to Intelligence Activities and Investigations Arising Out of the 2016 Presidential Campaigns) began in 2019 when the U.S. Justice Department designated federal prosecutor John Durham to review the origins of an FBI investigation into Russian interference in the 2016 United States elections. Durham was given authority to examine the government's collection of intelligence about interactions between the 2016 presidential campaign of Donald Trump and Russians, and to review government documents and request voluntary witness statements.
