One Alabama congressman Wednesday yelled in the face of Rep. Adam Schiff, the Democrat from California among the impeachment inquiry leaders, while another got into a shouting match with a CNN reporter and gave a thunderous speech.

This was the role played by two representatives from Alabama as House Republicans stormed the Capitol basement room where the intelligence committee was scheduled to hear testimony that could lead to an effort to remove President Donald Trump from office.

U.S. Reps Mo Brooks of Huntsville and Bradley Byrne of Fairhope, both fierce supporters of Trump, played high-profile roles on a dramatic day in the Capitol as Republicans amped up their opposition to the Democrats’ impeachment inquiry process to perhaps an unseen level. Brooks and Byrne this week were the only Republican members of the Alabama House delegation to vote against a resolution condemning Trump for removing U.S. military forces from Syria.

Byrne “was yelling” at Schiff as part of about two dozen GOP members of Congress forced their way into the secure room to protest the process by which the Democratic-controlled House is proceeding with the impeachment inquiry, CNN reported.

More details: Byrne was yelling in Schiff’s face. Rep. Val Demings shouted back at both Byrne and Louie Gohmert, who were yelling about the process.

Brooks, meanwhile, gave a fiery speech before joining the Republicans forcing their way into the committee hearings in which he demanded, "By golly, if they are going to do it, do it in public. Don’t hide it from the American people."

A third Alabama congressman, Gary Palmer of Hoover, also joined the Republicans’ charge.

Schiff did not engage with Byrne, CNN reported, but said other Democrats – including Rep. Val Demings of Florida, shouted back at both Byrne and Texas Congressman Louis Gohmert.

In a video posted on his Twitter account following the showdown, Byrne described the impeachment inquiry process as "a sham. They just showed the sham that it is by the way they conducted themselves just now."

Adam Schiff just SHUT DOWN his secret underground impeachment hearing after I led a group of Republicans into the room. Now he's threatening me with an Ethics complaint!

Republicans barged in just before testimony began from Deputy Assistant Secretary of Defense Laura Cooper, The Washington Post reported. The House intelligence committee – made up of both Democrats and Republicans – have been hearing testimony related to the impeachment inquiry from witnesses in the Capitol's secure SCIF room in the basement of the building.

Schiff left the meeting room with Cooper, Rep. Michael Waltz of Florida said after exiting the room.

“We simply very calmly, politely walked into the room, sat down and were ready to hear the proceedings,” Waltz said in a press conference after the incident, according to video posted by The Post.

Byrne said there was no shouting in the room.

"There was talking after Adam Schiff and the witness left but not before," Byrne said at the press conference with Waltz. "That's critical. We came in and sat down to hear testimony – all four of us are on (the House) Armed Services (committee). This is a deputy secretary of defense (who was scheduled to testify). This is an Armed Services matter, not an Intelligence (committee) matter."

Byrne reiterated that point in his Twitter video.

"I'm on the Armed Services Committee," Byrne said. "They would not let the witness go forward with us in the room even though we're on the committee of jurisdiction."

Brooks -- who is also on the House Armed Services Committee -- had an intense exchange with CNN reporter Manu Raju Wednesday as Raju asked Brooks about the written opening statement testimony from Tuesday.

"The opening statement doesn't make any difference!" he said. Asked about the substance, "it doesn't make any difference" pic.twitter.com/1O7KXkvClE — Manu Raju (@mkraju) October 23, 2019

"If you were in a court of law, would you just rely on the opening statement of an attorney?" said Brooks, an attorney and former prosecutor. "Or the first witness called? Or would you have cross examination? Would you allow rebuttal witnesses to determine, to explore, whether the first witness testimony was accurate?"

Brooks also described the inquiry to the CNN reporter as a "sham process."

“Show your face so we can all see the travesty that you are trying to foist on America and the degradation of our republic that you are engaged in,” Brooks said in his brief speech before Republicans entered the hearing room. "We demand open proceedings, the American people deserve nothing less, their representatives in congress deserve nothing less.”
