Democrats objected to Goodlatte's repeated attempts to get Strzok to answer.
Judiciary ranking member Jerrold Nadler of NY took sharp exception to Goodlatte's threat.
Trump responded by questioning why Ghazala, who stood at her husband's side during the DNC speech, didn't speak herself.
"At the conclusion of the day, we will be recessing the hearing and you will subject to recall to allow the Committee to consider a contempt citation", Goodlatte said.
"It would be his candidacy for the presidency", Strzok said.
As you know, Strzok was one of the key agents involved in investigating Russian interference, and in 2017 he was assigned to special counsel Robert Mueller's probe of the Russia scandal.
Gowdy has repeatedly slammed Strzok and other top FBI officials for being politically biased against Trump, and suggested that Strzok allowed bias to affect decisions he made in the FBI's Russian Federation probe and the investigation into Hillary Clinton's use of a private email server.
At one point, Strzok said he didn't appreciate an assertion from Gowdy, who retorted, "I don't give a damn what you appreciate". After Page asked Strzok whether Trump would win the election, Strzok replied that he would not, adding that "we'll stop it". "My presumption based on that terrible, disgusting behavior [was] that the American population would not elect somebody demonstrating that behavior to be president of the United States". It simply couldn't happen. "Together with her lover, FBI Agent Peter Strzok, she worked on the Rigged Witch Hunt, perhaps the most tainted and corrupt case EVER!" He described the texts as "hate filled and biased".
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.
Strzok and former Federal Bureau of Investigation lawyer Lisa Page were having an extramarital affair during the 2016 campaign and exchanged thousands of politically charged texts.
Strzok also said he was one of the few people during the 2016 USA election who knew the details of Russian election interference and its possible connections with people in the Trump orbit, and that information could have derailed Trump's election chances.
Peter Strzok said he had information with "the potential to derail and quite possibly defeat" Trump but said the "thought of expressing that or exposing that information never crossed his mind".
For a brief moment, lawmakers floated the idea of Strzok having some company when he appears Thursday - as the committee offered Page a spot to testify at Thursday's hearing.
Strzok also worked on Special Counsel Robert Mueller's inquiry into alleged collusion between the Trump campaign and Russian Federation.
"I hesitate in part because of my gut sense and concern there's no big there there", Strzok said in the text.
The White House said President Trump is monitoring the hearing from Europe.
In an interview with investigators with the Justice Department's Inspector General, Page said she was "totally appalled that the President would insult the father of a dead service member".
The text exchange at issue was detailed in a recently-released Justice Department internal watchdog report, which revealed that on August 8, 2016, now ex-FBI lawyer Lisa Page wrote in a text, Trump is "not ever going to become president, right?"
Strzok appeared before lawmakers in Congress last month for a closed-door interview.
