Rep. Louie Gohmert believes the Justice Department is spying on him, he said Monday on Fox News, without offering any evidence to support his claim.

The DOJ declined to comment when asked about the veracity of Gohmert’s assertion.

The Texas Republican said his friends in the intelligence community in Washington have told him that he is “being watched” by department officials while the House Judiciary Committee, of which he is a member, investigates potential Foreign Intelligence Surveillance Act abuses during the FBI’s 2016 investigation into possible ties between President Donald Trump’s campaign and Russia.

Gohmert said he did not believe that he was being watched by the agency when someone first told him about it. But after working on a 48-page “exposé” on special counsel Robert S. Mueller III, he said he realized, “My gosh, this is their mode of operation.”

Four different federal judges found cause to approve a FISA application from the FBI in 2016 to monitor the international communications of Trump campaign aide Carter Page. The bureau said it had reason to believe Page was a Russian intelligence asset.
