The Senate Homeland Security Committee was the scene of a heated exchange between Chairman Sen. Ron Johnson (R-Wis.) and Ranking Member Sen. Gary Peters (D-Mich.), on Wednesday, Dec. 16.

Johnson was fired up as he refuted claims by Peters that he had spread Russian disinformation regarding Hunter Biden.

“I just have to talk about Russian disinformation because the people peddling it are not on my side of the aisle,” Johnson said. The reality is that Peters is the one spreading lies, a fired-up Johnson told the committee, which was meeting to discuss the 2020 election irregularities.

“Senior Democrat leaders, including Ranking Member Peters,” he continued, “they were involved in a process of creating a false intelligence product, it was supposed to be classified, they leaked to the media, that accused Sen. [Chuck] Grassley, the president pro tempore of the Senate, and myself of accepting and disseminating Russian disinformation.”

Peters had “introduced false information” into the committee said Johnson, which was itself Russian disinformation. Democrats, he said, after calling revelations about Hunter Biden’s laptop “Russian disinformation,” then discovered there was a genuine investigation by the DOJ that is continuing, into Hunter Biden.

“So it’s just galling—and I have to point out—that the purveyors of Russian disinformation, Hillary Clinton’s campaign, the DNC, the Steele dossier, the ranking member Peters accusing Sen. Grassley and I of disseminating Russian disinformation—that’s where the disinformation is coming, the lies, the false allegations.”

Peters then added fuel to the fire by insisting he had nothing to do with the document Johnson had referred to. Johnson immediately interjected, “You lied repeatedly. You lied repeatedly to the press that I was spreading Russian disinformation, and that was an outright lie, and I told you to stop lying and you continued to do it.”

Peters then told Johnson that the hearing was not meant “for the airing of grievances,” as Johnson banged his gavel and tried to move on, reports Fox News.

“This is terrible what you’re doing to this committee,” Peters yelled.

“It is what you have done to this committee, falsely accusing the chairman of spreading disinformation,” Johnson fired back. “Nothing could have been further from the truth and you’re spouting it again, which is why I had to respond.”
