Strzok was an FBI official, Counterintelligence Division and led the FBI investigation into the Clinton personal email server. Strzok also originated the FBI Operation Crossfire Hurricane to investigate Russian interference in the 2016 election. He was removed from the Mueller investigation after personal text messages to FBI attorney Lisa Page revealed a bias against Trump.

Peter Strzok: “No, no he’s not. We’ll stop it.”
