Asked by Jackson later in the hearing about what affect Trump's tweet had on officials in the bureau, Wray said FBI staffers "are big boys and girls" who "understand that we will take criticism from all corners".
WASHINGTON DC, USA - FBI Director Christopher Wray defended his agency Thursday, December 7, against President Donald Trump's criticisms, amid a mounting Republican push aimed at discrediting the probe into alleged collusion between the US leader's campaign and Russian Federation in last year's election.
Their criticism comes as Special Counsel Robert Mueller has charged four people from Trump's inner circle since October as part of an investigation into Russian meddling in the 2016 US presidential election.
Wray also faced questions about potential legal trouble for Trump personally arising from Mueller's investigation.
"My hunch is it has something to do with the dossier", Jordan said.
Jordan laid out a scenario in which he said he believes it may have been Strzok who brought the dossier to a FISA court to obtain clearance for surveillance on members of the Trump campaign.
"And if this happened, if you have the Federal Bureau of Investigation working with the Democrats' campaign, to take opposition research, dress it all up and turning it into an intelligence document to take it to a FISA court so they can spy on another campaign, if that happened, that is as wrong as it gets..."
"I think it would not be appropriate for me to speculate about what the inspector general will or will not find", Wray said.
The House Judiciary Committee chairman, Rep. Here's the panel's Republican chairman, Bob Goodlatte. But it appears that it was more than just a few texts, as initially reported.
Meanwhile, the Washington watchdog Judicial Watch has released an email showing another Mueller deputy, Andrew Weissmann, praised outgoing acting Attorney General Sally Yates for refusing to defend Trump's controversial travel ban.
Meantime, Fox News has learned that a senior Justice Department official was demoted this week amid an ongoing investigation into his contacts with the opposition research firm responsible for the anti-Trump "dossier". Republicans on the House Judiciary Committee agreed with that assessment Thursday.
"Investigations must not be tainted by individuals imposing their own personal political opinions", he said during the hearing Thursday. Trump loves the "courageous" agency when it's digging into Hillary Clinton's activities, but he blasts agents when they might be coming for him, Tapper pointed out Thursday.
Wray assured the committee that an inspector general is investigating the handling of the Clinton email investigation.
Wray refused to answer, saying, "I'm not prepared to discuss anything about a FISA process in this setting".
Electronic records show Strzok changed Comey's earlier draft language describing Clinton's actions as "grossly negligent" to "extremely careless", sources said. "You, Director Wray, have a unique opportunity to fix the damage".
Democrats, however, sought to focus on Trump's comments and actions, and the actions of members of his campaign past year.
