"We're going to have plenty of theatrics," said Rep. Doug Collins (R-GA), who sternly defended both the President and Whitaker from the outset.
"Bring your popcorn - I'm thinking about just setting up a popcorn machine in the back, because that's what this is becoming," Collins said.
In the first round of questioning from Rep. Jerry Nadler (D-NY), the Chairman of the House Judiciary Committee, Whitaker sparred with Nadler over his questions, at one point saying that Nadler's time had run out, prompting howls of laughter from Democrats on the panel.
“You wouldn’t oversee a witch hunt, would you?” Rep. Steve Cohen (D-TN) asked Whitaker, using the favored phrase of President Trump about the Mueller investigation.
“Congressman, it would be inappropriate for me to comment on an ongoing investigation," Whitaker answered.
Republicans meanwhile used their time to explore their contention that the Russia investigation has been out of control - and biased against the President - from the start, as Collins asked Whitaker if there had been a leak from inside the Justice Department to CNN about the January indictment and arrest of political operative Roger Stone.
"Mr. Collins, I share your concern with the possibility that a media outlet was tipped off," Whitaker answered.
CNN has previously reported they had cameras there because of good reporting, and a reporter's hunch - not any leak from inside.
Other GOP lawmakers focused on regular issues before the Justice Department, like illegal drugs, and border security, as Republicans said there was no need for Democrats to haul Whitaker before Congress, especially since he will be replaced next week by William Barr, whose nomination awaits action in the full Senate.
