GOP Rep. Dan Newhouse, Wash., issued a statement saying he would vote yes on the article of impeachment shortly before speaking on the House floor.

"These articles of impeachment are flawed, but I will not use process as an excuse. There's no excuse for President Trump's actions," Newhouse said.

"Last week there was a domestic threat at the door of the Capitol, and he did nothing to stop it. That is why with a heavy heart and clear resolve I will vote yes on these articles of impeachment."

Roughly two dozen Democrats on the House floor applauded Newhouse when he announced his plans to vote to impeach Trump.

Shortly after, Rep. Jaime Herrera Beutler, R-Wash., said she will also vote to impeach Trump in her floor marks. She had previously announced her intentions to break from the president, and said on the floor it's not a "fear-based decision."

No House Republicans voted to impeach Trump in 2019.

As the House debates impeaching him a second time, President Donald Trump issued a statement Wednesday urging for “‘NO violence, NO lawbreaking and NO vandalism.’

“In light of reports of more demonstrations, I urge that there must be NO violence, NO lawbreaking and NO vandalism of any kind,” Trump said in the statement.

“That is not what I stand for, and it is not what America stands for,” he added. “I call on ALL Americans to help ease tensions and calm tempers. Thank You.”

After several conservative House Republicans aligned with Trump criticized Republican Conference Chair Liz Cheney -- the No. 3 in GOP leadership -- after she announced she would support impeachment Tuesday evening, Cheney fired back to their calls to step down through reporters on Capitol Hill.

"I'm not going anywhere," she said Wednesday afternoon. "This is a vote of conscience. It's one where there are different views in our conference. But our nation is facing an unprecedented, since the Civil War, constitutional crisis. That's what we need to be focused on. That's where our efforts and attention need to be."

House Minority Leader Kevin McCarthy delivered a speech on the House floor against impeaching Trump, arguing that a vote to impeach would "fan the flames of partisan division" and that instead the president could bear responsibility through a censure resolution.

McCarthy began by condemning last week's attack on the Capitol as "undemocratic, un-American and criminal," and although there to defend him, quickly broke from the president in making the distinction that antifa was not to blame for the violence, as Trump has privately suggested.

"Some say the riots were caused by antifa. There is absolutely no evidence of that. And conservatives should be the first to say so," McCarthy said, calling on his colleagues.

"I believe impeaching the president in such a short timeframe would be a mistake," McCarthy said, notably not directly defending his actions as unimpeachable but taking issue with the timing.

"A vote to impeach will further divide the nation. A vote to impeach will further fan the flames of partisan division," he said. "That doesn't mean the president is free from fault."

McCarthy suggested that "a fact-finding commission and a censure resolution would be prudent" but "unfortunately, that is not where we are today." He stressed it's a time "to unite once again as Americans."

With the first procedural debate wrapped and a second procedural vote on deck, the House of Representatives will soon debate the article of impeachment -- charging the president with "Incitement of insurrection."

At least once during the hearings, lawmakers were reminded by the presiding officer that masks are required on the House floor at all times.

Rep. Sheila Lee Jackson, D-.N.Y., appeared to summarize the heart of Democrats' arguments when speaking ahead of the imminent impeachment vote.

"The president of the United States is an insurrectionist," she said. "He led an insurrection against the United States of America."

"The president provoked these domestic terrorists with words, with actions, with conduct, that portray and have contempt and hostility to the national value of equal justice under the law, telling domestic terrorists -- nearly all of them white supremacists -- many of them who support them politically -- who stormed the Capitol to derail Congress for derailing its constitutional required duty of counting the vote," she said. "He must be impeached because he is a threat."

Rep. Ilhan Omar, D-Minn., a strong critic of Trump's who called to impeach Trump last week while the siege was ongoing, said it's about holding the president accountable, as their oath as lawmakers requires, she said.

"It was a violent attempt to interrupt our democratic process," said Omar, who also called Trump a "tyrant." "We cannot simply move past this or turn the page. For us to be able to survive as a functioning democracy, there has to be accountability."
