Gabe Sterling, the chief oversight officer of Georgia's election, said trying to combat misinformation spread by Trump and his team was "kind of like a shovel trying to empty out the ocean," adding that he even argued with his own family members over the 'big lie.'

With Rep. Adam Schiff, D-Calif., asking the Georgia election officials about threats made against them, Sterling said the "straw that broke the camel's back" for him was a message to a Dominion contractor which said, "You committed treason -- May God have mercy on your soul," accompanied with a "slowly twisting GIF of a noose," he said.

"I lost my temper, but it seemed necessary at the time because it was just getting worse," Sterling said.

The committee went on to play a video of him from December 2020 in which he pleaded with Trump to "stop inspiring people to commit potential acts of violence."

Georgia Secretary of State Brad Raffensperger was the first to testify after a short recess and was immediately asked by Rep. Adam Schiff, D-Calif., to address the false allegations of widespread voter fraud Trump and his allies pushed in the battleground state.

"Our election went remarkably smooth," Raffensperger said. "President Biden carried the state of Georgia by approximately 12,000 votes," he reminded.

Raffensperger, a Republican who supported Trump's re-election bid, recounted how three separate audits in the state confirmed President Joe Biden as the winner.

"Three counts -- all remarkably close -- which show that President Trump did come up short," he said.

The committee showed evidence that Sen. Ron Johnson, R-Wis., attempted to deliver slates of "fake" Trump electors from Wisconsin and Michigan to then-Vice President Mike Pence.

Text messages the House panel obtained between Johnson staffer Sean Riley and Pence aide Chris Hodgson were displayed on-screen during Tuesday's hearing.

Riley wrote that Johnson wanted to hand over fake electors from the two states -- which Joe Biden won -- to Pence ahead of Jan. 6.

"Do not give that to him,” the Pence aide replied.

After the evidence was presented, a spokesperson for Johnson's office denied that the senator had any involvement in the creation of fake alternate slates of electors and claimed he had "no foreknowledge" it was going to be delivered to the office.

"The senator had no involvement in the creation of an alternate slate of electors and had no foreknowledge that it was going to be delivered to our office. This was a staff to staff exchange. His new Chief of Staff contacted the Vice President’s office. The Vice President’s office said not to give it to him and we did not. There was no further action taken. End of story," Alexa Henning, a spokesperson for Johnson, told ABC News.

Arizona House Speaker Rusty Bowers emotionally recounted the pushback he and his family faced under immense pressure from Trump's top team, who tried to convince him there was a law in Arizona that would have allowed him to overturn electors in the state -- which did not legally exist.

Bowers summarized the effort to go around him and send fake Arizona electors to Washington as a "tragic parody" and recounted from his personal journal how people turned on him as Trump continued to espouse the 'big lie.'

"It is painful to have friends who have been such a help to me turn on me with such rancor," he said. "I may, in the eyes of men, not hold correct opinions or act according to their vision or convictions, but I do not take this current situation in a light manner, a fearful manner, or a vengeful manner."

"I do not want to be a winner by cheating," he added. "I will not play with laws I swear allegiance to with any contrived desire towards deflection of my deep, foundational desire to follow God's will as I believe he let my conscience to embrace. How else will I ever approach Him in the wilderness of life knowing that I ask of His guidance only to show myself a coward in defending the course he led me to take."

He mentioned the threats around his home and how it upset is daughter, Kacey Rae Bowers, who was gravely ill at the time. She passed away at age 42, just days after the attack on the Capitol, on Jan. 28, 2021.
