Schiff told reporters that during the Tuesday interview "Mr. Gowdy took the role as a second attorney for Mr. Kushner," according to Bloomberg News.

Kushner, the president's son-in-law and a senior White House adviser, appeared before the panel on Tuesday to testify about a June 2016 meeting between the president's eldest son, Donald Trump Donald John TrumpBubba Wallace to be driver of Michael Jordan, Denny Hamlin NASCAR team Graham: GOP will confirm Trump's Supreme Court nominee before the election Southwest Airlines, unions call for six-month extension of government aid MORE Jr., and a woman described as a Russian government lawyer offering dirt on Hillary Clinton Hillary Diane Rodham ClintonJoe Biden looks to expand election battleground into Trump country Biden leads Trump by 12 points among Catholic voters: poll The Hill's Campaign Report: Biden goes on offense MORE.

The interview took place behind closed doors and under oath, according to Gowdy, who told The Hill on Tuesday that he found Kushner cooperative and forthcoming in his answers. He accused Democrats of unnecessarily dragging out the interview, which lasted over three hours.

Rooney on Wednesday echoed that assessment, but denied that there was any tension between Democrats and Republicans during the session.

The remark "totally surprises me," he said.

Just prior to being asked about Schiff's remarks, Rooney had praised the professionalism and bipartisanship of the committee's work.

"The Intelligence Committee has always separated itself from other committees in that we're not very partisan when we're down there. There's no grandstanding. I think people are trying to get the bottom of what they truly believe is an issue," he told reporters. "The only time we fight is over the timing of who's up and whose turn is it, and that's not a fight."

But the intelligence panel's investigation has already come close to the brink of partisan breakdown once — an incident that resulted in Rooney's elevation to an investigation leader.

Earlier in the year, House Intelligence Chairman Devin Nunes (R-Calif.) stepped back from the probe after making a clandestine trip to the White House to view documents he says revealed inappropriate unmasking of transition team officials.

That revelation quickly devolved into partisan infighting that threatened to derail the House panel’s investigation. Rep. Mike Conaway (R-Texas), assisted by Gowdy and Rooney, took over the probe in Nunes’s place, and the fracas had largely died down since.

Nunes has said that he temporarily stepped aside but did not recuse himself.

He was inside the House Intelligence Committee's secure space during the Kushner interview on Tuesday, but it's not clear whether he attended the meeting.
