Judicial Watch is seeking documents from the CIA over 2016 communications between former CIA Director John Brennan and then-Sen. Harry Reid (D-Nev.)

Chris Farrell, the group's director of investigations and research, said Monday that he believes Reid was part of the larger effort to undermine the Trump campaign and create a narrative of collusion with Russia.

Farrell said on "Fox News @ Night" that the "stop-Trump gang" used a variety of ways to feed a media narrative of collusion and create a false perception. The group wants to know whether Brennan fed information to Reid so that it could be publicized. 

Reid wrote a letter to then-FBI Director James Comey in 2016, two days after being briefed by Brennan, stating:

"The evidence of a direct connection between the Russian government and Donald Trump's presidential campaign continues to mount. ... The American people deserve to have a full understanding of the facts from a completed investigation before they vote this November."

Farrell said that Reid's message was part of an "echo chamber" around Trump and Russia. 

"It's how the public is manipulated, it's how the media is manipulated, and all you need is the tiniest little kernel of half-truth," he said.

In 2012, Reid said on the Senate floor that "the word's out" that then-presidential candidate Mitt Romney hadn't paid taxes for 10 years.

Farrell replied that Reid's words are "rumor" and "innuendo," and that he didn't care about facts.

"It's slanderous in many cases," he added, saying that in the case of alleged collusion, Reid is part of a "deliberate, orchestrated act."

Shannon Bream then referenced the book “Russian Roulette,” by Michael Isikoff and David Corn, which noted that Reid was the lone member of the so-called "Gang of Eight" who took action after Brennan briefed them.

"One of the ways to move the narrative out of the CIA and get it into the media stream ... is to have Reid act as a channel to do that," Farrell said.
