The top Democrat on the House Intelligence Committee has invited FBI counterintelligence agent Peter Strzok to appear before the panel.

Strzok has faced a barrage of attacks from President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

“We would like to extend an invitation to Mr. Strzok to appear for a voluntary interview as part of our ongoing probe into Russia’s interference in the 2016 U.S. election,” Schiff wrote in a Tuesday letter to Strzok’s lawyer, Aitan Goelman.

DOJ Inspector General Michael Horowitz released a scathing report about FBI conduct last week, expressing profound concern about the messages Strzok sent to Page.

One major bombshell revelation in the inspector general's 500-page report was Strzok telling Page they would “stop” Trump from becoming president, a fact that GOP lawmakers seized on during Horowitz’s two hours-long testimonies on Capitol Hill this week.

The report found no evidence that political bias had affected the FBI's investigation.

But Republicans have seized on the texts as proof of political bias within the top levels of the federal government.

Critics on the right have also drawn attention to Strzok's work at the beginning of special counsel Robert Mueller Robert (Bob) MuellerCNN's Toobin warns McCabe is in 'perilous condition' with emboldened Trump CNN anchor rips Trump over Stone while evoking Clinton-Lynch tarmac meeting The Hill's 12:30 Report: New Hampshire fallout MORE’s investigation into ties between the Trump campaign and Russia.

Schiff noted that Republicans on the committee had notified the DOJ in January about the committee’s intentions to interview Strzok, but they ultimately did not offer him the opportunity to speak before the committee “for reasons that remain unclear.”

“We would welcome the opportunity to finally hear from Mr. Strzok,” Schiff wrote.

Schiff offered the FBI official a closed-door interview that would cover unclassified and classified matters, parts of which could then be released in an unclassified portion of the transcript if Strzok agrees.
