After Rep. Sheila Jackson Lee (D-TX) requested to have her five minutes of allotted time reset, Whitaker paused before answering her question - stating "I don't know if your time's been restored or not."
"Mr. attorney general, we are not joking here," said Jackson Lee. "And your humor is not acceptable."
Acting Attorney General Matt Whitaker shocked the room during a contentious exchange with House Judiciary Committee chairman Jerrold Nadler (D-NY), when he reminded Nadler that his time had run out for questioning.
"Mr. Chairman, I see that your five minutes is up," said Whitaker - resulting in audible gasps throughout the packed committee hearing.
"I am here voluntarily. We have agreed to five minute rounds," he added.
Nadler began laughing, and pointed out that they did not enforce the 5-minute rule on Whitaker.
Whitaker's comment came after Nadler asked whether the acting AG has had any role in approving any "request or action to be taken by the special counsel."
