Sen. Ron Johnson (R-Wis.) appeared to shock Bret Baier on Fox News when he said an informant revealed that officials of the FBI had organized off-site meetings of the "secret society" mentioned in a text from FBI agent Peter Strzok.

Here's the video of Johnson's claim:

"What this is all about is further evidence of corruption, more than bias, but corruption at the highest levels of the FBI," Johnson explained.

"And that secret society," he continued, "we have an informant that's talking about a group that was holding secret meetings off-site. There's so much smoke here, there's so much suspicion..."

"Let's stop there," Baier interrupted, "a secret society, that, secret meetings off-site of the Justice Department?"

"Correct," Johnson replied.

"And you have an informant saying that?" Baier asked, incredulously.

"Yes," he answered.

"Is there anything more about that?" Baier asked.

"No, we have to dig into it, that's," Johnson responded, "that's, this is not a distraction, again, this is, this bias, potentially corruption at the highest levels of the FBI that is now investigating, and now this, and by the way Robert Mueller used to run the FBI, he is in no position to do an investigation over this kind of misconduct."

"So I think at this point in time we probably should be looking at a special counsel to undertake this investigation," he concluded, "but Congress is going to have to continue to dig."

The investigation is heating up

A report Tuesday revealed that Mueller had interviewed Attorney General Jeff Sessions for hours in the Russian investigation, and the Washington Post reported that Mueller was requesting to interview the president over his dismissal of James Comey and Mike Flynn.

Allies of the president have used texts released from FBI official Peter Strzok to accuse the FBI and the Department of Justice of bias against the president. Several lawmakers, like Johnson, are calling for a second special counsel to be named in order to investigate the alleged corruption at the two institutions.
