".@RepAdamSchiff’s calm, professional leadership is something we should all be proud of," Pelosi tweeted Friday. "Unlike his predecessor, his time as Chairman of the House Intelligence Committee has been a shining example of how to responsibly carry out the committee’s mission."

On Thursday, Pelosi called Nunes's behavior as the previous chairman of the committee "almost criminal" during a press conference and also criticized those targeting Schiff. 

"They're afraid of the truth; they're afraid of competence; they're afraid of a leader who is recognized in our country for being calm, professional, patriotic," she said. "I'm so proud of the work of Chairman Adam Schiff — in stark contrast to the irresponsible, almost criminal behavior, of the previous chair of the committee."

"Congressman Adam Schiff, who spent two years knowingly and unlawfully lying and leaking, should be forced to resign from Congress!" he wrote. 

Barr on Sunday told Congress that Mueller's report on his investigation into Russia interference in the 2016 election did not contain evidence that Trump's campaign coordinated with Moscow and did not provide sufficient evidence to pursue and obstruction of justice charge against him.

Schiff has said that his Intelligence Committee will continue its own investigations into the president. 

Nunes has been a strong supporter of Trump. When he was head of the committee, Republicans released an intelligence memo claiming that the Justice Department had abused its surveillance powers.
