Judicial Watch President Tom Fitton said it's "shameful" that Deputy Attorney General Rod Rosenstein only turned over the FBI memo that instigated the bureau's Russia investigation after being threatened with legal action.

Rosenstein allowed House Intelligence Committee chairman Rep. Devin Nunes, R-Calif., and Rep. Trey Gowdy, R-S.C., to view the FBI memo after Nunes threatened him and FBI Director Christopher Wray with legal action -- including contempt proceedings and impeachment.

A government source told Fox News that Nunes, Gowdy and committee Republican staff were able to view the two-page memo with relatively few redactions.

"It shows you just how obstructionist [the] FBI and Justice Department have been with a Republican Congress," Fitton said on "Outnumbered Overtime" on Thursday. "This is a deep state obstruction, and it's shameful that this Justice Department and this FBI only turned over this document after being threatened with contempt and the officials at issue being threatened with impeachment."

He argued this Justice Department and FBI have a "demonstrated history" of withholding records related to the targeting of President Trump and his associates because they expose "misconduct" by DOJ and FBI officials.

"Why was it the Justice Department and FBI took the extraordinary step to investigate the Trump campaign given the information they had that Russia was targeting the Trump campaign or Donald Trump with malicious lies, specifically through the dossier?" Fitton asked.

He suggested that officials may have opened the investigation for partisan reasons, as opposed to law enforcement or counterintelligence reasons.
