Peter Strzok is the FBI official who opened the investigation into the Trump campaign in 2016. Strzok was fired last year after an inappropriate relationship with a colleague was discovered along with questions about Trump bias.
A member of the Trump administration told Fox News' Gregg Re on Tuesday that Attorney General William Barr has assembled a team to investigate the origins of the Obama administration's FBI counterintelligence investigation of the Trump campaign during the 2016 presidential election.
During a congressional hearing on Tuesday, Barr said: "I am reviewing the conduct of the investigation and trying to get my arms around all the aspects of the counterintelligence investigation that was conducted during the summer of 2016."
Barr's testimony came after he sent a letter to Congress in late March that revealed that Special Counsel Robert Mueller's Russia investigation found no evidence of collusion between the Trump campaign and Russia.
Fox News also exclusively reported that "the Justice Department's Inspector General (IG) is separately looking into whether Comey mishandled classified information by including a variety of sensitive matters in his private memos" and is also looking into "the FBI's FISA application process."
