Forest Gump: Peter Strzok has been involved in both Trump and Clinton-focused probes - and texted his lover anti-Trump messages

The FBI agent who was dismissed from special counsel Robert Mueller's Russia probe for sending his lover anti-Trump text messages is turning into a Forrest Gump character who figured in a number of key moments in the Bureau's recent history.

Peter Strzok was reassigned to the FBI's human resources department after the text messages between him and FBI lawyer Lisa Page were uncovered. He was already known to be the agent who who edited then-Director James Comey's reprimand of Hillary Clinton for using an unsecured private email server for classified messages.

Strzok, among the top officials investigating Clinton, changed Comey's description of her conduct from 'grossly negligent' – language that mirrors the criminal code – to the softer words 'extremely careless.'

His photograph was revealed by Fox News.

Now it can be revealed that Strzok was also part of the team that quizzed disgraced former National Security Advisor Michael Flynn before he pleaded guilty to lying during that interview.

And he participated in the FBI's sit-down interviews with two Clinton insiders linked to her email scandal, both of whom got a free pass despite making statements to agents that were later challenged by other records.

Peter Strzok softened Comey's language on Hillary Clinton, interviewed her top aide Cheryl Mills and recommended no action on her statements despite them contradicting what she said elsewhere, but interviewed Trump's national security adviser Mike Flynn before he took a deal

The email probe included question-and-answer sessions with several senior Clinton aides including lawyer Cheryl Mills and chief of staff Huma Abedin.

And when those two friends-of-Hillary sat down for their third-degree sessions, Strzok – the partisan anti-Trump agent – was asking many of the questions.

Mills and Abedin both denied knowing of Clinton's unorthodox email server setup, according to summaries of their interviews that the Bureau released last year.

'Mills did not learn Clinton was using a private server until after Clinton's [State Department] tenure. Mills stated she was not even sure she knew what a server was at the time,' one agent's interview notes read.

And Abedin told agents, they wrote, that she 'did not know that Clinton had a private server until about a year and a half ago when it became public knowledge.'

But in emails released by State, Mills and Abedin both referred to Clinton's server specifically, The Daily Caller reported Monday.

Then-FBI Director James Comey defended the Clinton aides' contradictory statements when he testified in a House Judiciary Committee hearing about six weeks before the 2016 election.

'Having done many investigations myself, there’s always conflicting recollections of facts – some of which are central, some of which are peripheral,' Comey said then.

President Trump railed against Strzok's actions on Sunday, as the Washington Post and New York Times reported that his text messages 'expressed anti-Trump sentiments and other comments that appeared to favor Clinton.'

ABC News had reported Strzok's departure from the Russia probe in August, but without offering a reason.

Now the controversy could taint not one, but two of the biggest federal investigations in the last year.

President Trump latched onto news reports that said FBI agent Peter Strzok was pulled off the Mueller probe after anti-Trump text messages were found. Strzok was also a lead investigator on the Hillary Clinton email probe, with Trump now suggesting bias

'Tainted (no, very dishonest?) FBI "agent's role in Clinton probe under review,"' Trump tweeted Sunday morning. 'Led Clinton Email probe. @foxandfriend Clinton money going to wife of another FBI agent in charge.'

The latter dig was meant for Deputy FBI Director Andrew McCabe, whose wife took campaign donations from a Clinton ally, the outgoing Virginia Gov. Terry McAuliffe.

The FBI has pointed out that McCabe had no role in the Clinton investigation until months after his wife's political campaign had concluded.

But Page, the lawyer who exchanged anti-Trump texts with Strzok, was on McCabe's staff.

Trump went after Strzok again by writing, 'Report: "ANTI-TRUMP FBI AGENT LED CLINTON EMAIL PROBE"'

'Now it all starts to make sense,' Trump said.
