"It taints the entire Mueller witch hunt".
Page defied that subpoena to appear on Wednesday before the House Judiciary and Oversight and Government Reform Committees.
And yet some analysts couldn't help but notice a hint of irony in Republicans' argument that Strzok's personal views must have influenced his official duty, while they simultaneously conduct investigations into politicians they openly support or oppose.
Her appearance also comes a day after Strzok, with whom Page was romantically involved, on Thursday attempted to explain for the first time in public his infamous text message saying "we'll stop" Donald Trump from being elected president.
Some may assume that if Strzok really wanted to sabotage the election of Trump all he had to do was leak the fact that the FBI was investigating Trump.
In one exchange, Strozk vowed to "stop" Trump.
"No. No he won't. That is bias. Agent Strzok may not see it but the rest of the country does, and it is not what we want, expect or deserve from any law enforcement officer much less the Federal Bureau of Investigation".
That episode was at the center of an exchange at the hearing-a hearing which immediately broke down into mutual disdain and even outright anger-that is now making the rounds. "Are you kidding?" Gowdy said when Strzok said his texts about impeachment weren't predetermining an outcome in the Russian Federation investigation.
Trump also told The Sun that May had ignored his advice on Brexit, telling the paper that "I would have done it much differently".
"I urge our chairmen to change course and to keep their promises to protect the integrity of the special counsel's investigation", Rep. Elijah Cummings (D-Md.) said in his opening statement Thursday.
Plus, he said, both the Clinton and Russian Federation investigations were handled by large teams that "would not tolerate any improper behaviour in me any more than I would tolerate it in them".
He said that his text messages critical of Trump shortly after the investigation began were in response to Trump's behavior on the campaign trail - and not a reflection of his investigative intent.
At the end of his monologue, Democrats in the committee chamber applauded.
But Republicans eager to undermine Mueller's investigation berated Strzok, holding up the texts as evidence of partisan bias within a law enforcement agency meant to steer clear of political considerations.
For of more Strzok's testimony, this video thread from Think Progress' Aaron Rupar is a great resource.
"If they go in a slightly different route, I hope you're going to be able to trade with the US", Trump said.
Thursday, Chris Meekins, a senior HHS official, said any delay in reunifying children was necessary to ensure they weren't being handed over to human smugglers posing as parents, or parents who pose a danger. He added, "I know there were many opinions expressed by people who were not part of the investigation - including people in government - but none of that mattered to us".
Mr Manafort's lawyers had been asking to have his 25 July trail date pushed back to allow him more time to prepare - a request that the judge recently denied.
Strzok had told Gowdy he was unable to answer a question related to the Russian Federation probe, saying he had been instructed not to comment on matters related to an ongoing investigation. Horowitz told lawmakers after the report's release that he is not confident that Strzok was unbiased during the FBI's investigation into Clinton's emails.
The FBI agent went on to assail Republicans for corroding "what the FBI is in American society", and impairing its capacity to execute its mission.
