Comey has been charged with making false statements and obstruction of a congressional proceeding. He has pleaded not guilty. His trial is expected to begin in January.

Justice Department Inspector General Michael Horowitz uncovered a series of anti-Trump text messages between Strzok and Page in 2018. Both were assigned to work on Special Counsel Robert Mueller’s team in 2017.

Page served on Mueller’s team on a short detail, returning to the FBI’s Office of General Counsel in July 2017. Strzok, though, was removed from the team and was reassigned to the FBI’s Human Resources Division. Prior to serving in the special counsel’s office, Strzok was a top agent in the bureau’s counterintelligence division.

Strzok is the FBI agent who, in July 2016, opened the FBI’s initial Russia investigation, which was nicknamed "Crossfire Hurricane" inside the bureau.

Page resigned from the bureau in May of 2018, and Strzok eventually was fired in August 2018.

Strzok was fired from the bureau in August 2018 after months of scrutiny regarding the anti-Trump text messages exchanged between himself and Page.

During congressional testimony in 2018, Strzok confirmed that he and Page were involved in an extramarital affair.
