Devin Nunes has demonstrated little interest in good faith leadership of the House Intelligence Committee over the past year. For all intents and purposes, the California congressman has abandoned his role as chairman of the panel to carry water for the White House and freelance at Fox News. Now that the first phase of his clandestine probe into the so-called Deep State plot against Donald Trump is complete, Nunes is apparently adding a new job to his ever-expanding skill set: carpentry.

On Thursday, CBS News reported that Nunes plans to construct a physical partition to separate Republican staffers on the House Intelligence Committee from their Democratic counterparts. While committee Republicans have denied any knowledge of the plan, they intimated that it was conceived by Nunes. “I’m not part of that decision,” Rep. Mike Conaway of Texas, who took over the committee’s Russia probe after Nunes was accused of running interference for the White House, told the outlet. “You’ve got to talk to Devin. I don’t know what they’re trying to do one way or the other.”

Republican Congressman Tom Rooney also pleaded ignorance. “I swear to God I didn’t know that,” he said, before noting the partisan toxicity that has plagued the panel: “The level of trust and the level of everything down there is—it’s poison. It’s absolute poison.” Rooney added that an ongoing ethics investigation into the “entire Republican staff” on the committee over alleged leaks has only added to the pervasive sense of distrust.

While partisan bickering over the Trump-Russia probe has long plagued the House Intelligence Committee, over the past two weeks the discord between Democratic and Republican lawmakers has reached a fever pitch over dueling memos about the F.B.I. and Justice Department decision to surveil former Trump campaign adviser Carter Page. Amid the skirmishes, Nunes has emerged for many Trump allies as a standard-bearer, prompting Adam Schiff and other Democrats to call for his resignation as chairman. Last week, Senate Minority Leader Chuck Schumer and House Minority Leader Nancy Pelosi also said the California Republican should step aside, and while Conaway expressed confidence in Nunes’s leadership, he conceded that he isn’t fully aware of his doings. “I’m doing all the Russia stuff and he’s doing all the investigatory things,” Conaway recently told CBS News. “I haven’t talked to him about where he goes from here.”
