Several pro-Trump activists surrounded House Judiciary Committee Chairman Jerry Nadler as he boarded a Longworth Office Building elevator during a break in Thursday's impeachment hearing.

'Shame on you Chairman Nadler, shame on you, you have broken your oath,' shouted Ben Bergquam, a MAGA-hat wearing activist who captured the encounter and posted it to social media. 'Because the American people see through it. It's going to work in President Trump's favor. Keep it up, keep it up,' he continued.

In the video, Nadler hits the button to close the elevator doors several times, but they keep reopening, leaving him susceptible for another round of insults.

'Trump 2020!' Bergquam yelled.

In video shot by DailyMail.com, another MAGA-hat wearing individual is seen huddled up alongside Bergquam also yelling pro-Trump slogans at Nadler.

The impeachment hearings have featured an occasional outburst.

On Monday at the top of the House Judiciary Committee's impeachment hearing Owen Shroyer, of the right-wing website InfoWars, started shouting from seats reserved for members of the public.

'Jerry Nadler is committing treason,' he yelled. He also declared that 'Trump is innocent.'

'You can kick me out of this hearing,' he informed members of the U.S. Capitol Police, who, indeed, promptly removed him.

During Monday's hearing Rep. Val Demings, a Florida Democrat, was briefly applauded by the audience.

When former Ambassador to Ukraine Maria Yovanovitch testified in front of the House Intelligence Committee last month she received a standing ovation upon the hearing's conclusion.

As for Bergquam, he made headlines earlier this year when he got arrested in Sacramento alongside right-wing activist Laura Loomer - who's now trying to run for Congress - trespassing at California Gov. Gavin Newsom's mansion.

Bergquam and Loomer were protesting Newsom's immigration position.

The Sacramento Bee reported that Bergquam and Loomer wore Mexican garb, with Bergquam sporting a faux mustache, and livestreamed their arrest.
