Chaffetz hopes Trump didn't call Comey 'nut job' to Russians

“I hope that’s not true," Chaffetz said.

Chaffetz added that he would prefer that Trump had confronted the Russians over their interference with the election. “You would like the president to beat them over the head over that,” he said on "This Week" Sunday.

The House Oversight Committee needs to see transcripts of all relevant conversations about the Russia investigation, Chaffetz said, referring to any written accounts of the Oval Office meeting with the Russians and Comey’s reported detailed memos of his own interactions with the president.

“It’s important to remember that nobody has even seen these documents,” the congressman said. “We’re certainly pursuing them and I hope we find them sooner rather than later.”

Chaffetz said he expects to speak with Comey on Monday.

“I want every note that they have," Cummings said to Stephanopoulos. "There have been so many lies and so many contradictions, so I’m hoping that the chairman will issue subpoenas.”

But Cummings stopped short of suggesting the president might ultimately face impeachment. “I think they we need to gather the facts,” he said. “I have been always one to be very careful as regards to gathering the facts and then coming to the conclusion.”
