Republican National Committee Chair Ronna McDaniel said Thursday that House Intelligence Committee Chair Adam Schiff, D-Calif., should resign for his comments about collusion.

“For TWO YEARS, Adam Schiff has been pushing the phony [Trump]-Russia collusion hoax. He’s been lying to the American people from a position of authority on the House Intelligence Committee,” McDaniel tweeted before special counsel Robert Mueller’s report was released. “There was NO collusion and NO obstruction. Schiff should resign.”

Schiff faced criticism from Republicans in March over the investigation, and in response listed the actions he believes showed evidence of collusion between the Trump campaign and Russia, including the 2016 Trump Tower meeting and the reported attempt to establish a communications backchannel.

“I think it’s immoral, I think it’s unethical, I think it’s unpatriotic, and yes I think it’s corrupt — and evidence of collusion,” he said, according to Vox.

“My colleagues may think it’s okay that the Russians offered dirt on the Democratic candidate for president as part of what was described as the Russian government’s effort to help the Trump campaign,” Schiff said. “My colleagues might think it’s okay that when that was offered to the son of the president — who had a pivotal role in the campaign — that the president’s son did not call the FBI, he did not adamantly refuse that foreign help. No, instead that son said he would ‘love’ the help of the Russians.”

Schiff announced on Thursday that the House intel panel has officially invited Mueller to testify about his investigation.
