John Durham testifies on FBI's Russia probe in highly anticipated Capitol Hill appearance.

John Durham, the special counsel who investigated the FBI's probe into possible links between Russia and former President Donald Trump's 2016 campaign, testified before Congress twice this week. Durham's report, released in May, was critical of the FBI, saying agents showed "confirmation bias" and finding that the basis for opening an investigation into whether Trump's campaign was coordinating with Russia in 2016 was "seriously flawed." Durham recommended in his report a career official be assigned to challenge the FBI's politically sensitive surveillance applications.
