House Intelligence Committee Republicans on Thursday demanded Chairman Adam Schiff, D-Calif., resign from his role on the panel during a hearing on Russian interference tactics, provoking a clash between the two parties.

Rep. Mike Conaway, R-Texas, a top member of the panel, told Schiff his claims of collusion between President Trump during the Mueller investigation and afterward undermine his ability to act as chairman of the committee.

“We have no faith in your ability to discharge your duties and urge your immediate resignation as chairman of the committee,” Conaway said.

Republicans accuse Schiff of leaking information from the panel to the news media and helping spread the narrative that the president colluded with the Russians in order to win the White House in 2016.

The Mueller report, according to a summary, found no evidence of collusion.

“Despite those findings you continue to proclaim to the media there is significant evidence of collusion,” Conaway said.

Schiff, who was sitting two seats away from Conaway, fired back at the GOP and listed the evidence he believes is proof of improper behavior between the Trump campaign and the Russians. He cited Trump’s son Donald Jr. seeking dirt on Democratic opponent Hillary Clinton and an attempt to build a tower in Moscow during the campaign as examples.

“I do not think that conduct, criminal or not, is OK,” Schiff said. “And the day we do think that is OK, is the day we look back and say America lost its way.”

After he took command of the committee in January, Schiff is reigniting an investigation Trump and his campaign team over Russian collusion during the 2016 race, despite Mueller’s findings.

“I think it’s moral, it’s unethical, it’s unpatriotic, and yes, I think it’s corrupt and evidence of collusion,” Schiff said.

A letter was sent to Schiff by all GOP members of committee, including ranking member Devin Nunes, calling for him to immediately resign.
