The prosecutor conducting the review, Connecticut U.S. Attorney John Durham, has expressed his intent to interview a number of current and former intelligence officials involved in examining Russia's effort to interfere in the 2016 presidential election, including former CIA Director John Brennan and former director of national intelligence James Clapper, Brennan told NBC News. -NBC
NBC learned of the 'lawyering up' from three former CIA officials "familiar with the matter," while two more anonymous leakers claim there's tension between the Justice Department and the CIA over what classified documents Durham has access to.
With Barr's approval, Durham has expanded his staff and the timeframe under scrutiny, according to a law enforcement official directly familiar with the matter. And he is now looking into conduct past Donald Trump's inauguration in January 2017, a Trump administration official said.
One Western intelligence official familiar with Durham's investigation leaked that Durham has been asking foreign officials questions related to former Trump campaign aide George Papadopoulos, who was fed the rumor that Russia had 'dirt' on Hillary Clinton by a Maltese professor, Joseph Mifsud. While US media has sought to portray Mifsud as a Russian asset, the self-described member of the Clinton foundation has far stronger ties to the West.
