The House has ended its first round of debate on impeachment and is taking the first procedural vote of the day.

This will likely take roughly 45 minutes to one hour, followed by a second procedural vote on the rule that could take the same amount of time.

After those votes, the House will begin two hours of debate on the impeachment article charging Trump with "incitement of insurrection."

Democrat Rep. James McGovern, the chairman of the House Rules Committee, when closing out the morning debate, said the impeachment vote will show who in Congress stands with the president "no matter what he does" and who stands up to him.

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."

House Leader Steny Hoyer, D-Md., began by stressing that Trump's action's last week "demand urgent, clear action by the Congress," and praised House Republican Conference Chair Liz Cheney and a handful of Republicans for agreeing with Democrats that Trump ought to be impeached.

"This is the daughter of the former Republican whip and former vice president of the United States of America. She knows of what she speaks, and she said this as well, 'There has never been a greater betrayal by a president of the United States of his office and his oath of Constitution," he said. "This is not, as Liz Cheney said, just some action. She characterized it as the biggest betrayal of any president of the United States in our history."

Hoyer went on to list GOP Rep. John Katko of New York, the ranking Republican on the Homeland Security Committee who Hoyer described as "not some back-bencher on your side of the aisle" and Rep. Adam Kinzinger of Illinois, among the five House Republicans who have publicly stated they'll vote to impeach the president.

"Mr. Kinzinger said this," Hoyer said, "If these actions are not worthy of impeachment, then what is an impeachable offense? There is no doubt in my mind that the president of the United States broke his oath and incited this insurrection."

Hoyer said other Republicans who he has talked to "in the past 24 hours" agree the president's actions are impeachable.

Democrats and Republicans are expected to debate for one hour -- equally divided between Democrats and Republicans -- before a procedural vote ahead of the chamber beginning debate on the impeachment article itself.

Democrat Rep. Jim McGovern, the chairman of the House Rules Committee, setting up that preliminary vote on the terms of the debate, called the Capitol a "crime scene" and the rioters "traitors" and "domestic terrorists" in an assault instigated by Trump, emphasizing, "We wouldn't be here if it weren't for the president of the United States."

McGovern described the day as "a ceremonial role for the Congress -- one that sends a message to the world that democracy persists -- but at a rally a mile and-a-half down Pennsylvania Avenue, Donald Trump was stoking the anger of a violent mob," he began. "He said Vice President Pence has to come through and told the mob to walk down to the Capitol."

"The signal was unmistakable. These thugs should stage a coup so Donald Trump can hang on to power, the people's will be damned. This beacon of democracy became the site of a vicious attack. Rioters chanted, 'Hang Mike Pence,' as a noose and gallows were built. Capitol Police officers were beaten and sprayed with pepper spray. Attackers hunted down lawmakers to hold them hostage or worse," McGovern continued.

"I saw evil, Mr. Speaker. Our country came under attack, not from a foreign nation but from within," he added. He also slammed Republicans for preaching unity from members who voted to overturn a free and fair election.

Republican Rep. Tom Cole -- one of the lawmakers who object to Electoral College results after the violent seige -- called Jan. 6 the "darkest day" of his long career in Washington, but said Democrats, instead of promoting unity, are looking to "divide us further" by pursuing Trump's impeachment.

Cole did not directly defend Trump's actions or rhetoric but argued in Congress, one week before Biden's inauguration, sets up a "flawed process."

The House of Representatives is poised to impeach President Trump for a second time on Wednesday for "incitement of insurrection," exactly one week after a violent siege on the U.S. Capitol left five people dead.

House Democrats have the votes to impeach Trump, who will become the first and only president in U.S. history to be impeached twice.

And in a turn of events, at least five House Republicans -- including No. 3 Rep. Liz Cheney -- have announced they, too, will vote to impeach Trump, even though no Republicans supported the effort during Trump's first impeachment proceedings related to the Ukraine matter in 2019. The other House lawmakers who say they'll vote to remove Trump include GOP Reps. John Katko, R-N.Y., Adam Kinzinger, R-Ill., Fred Upton, Mich., and Jaime Herrera Beutler, R-Wash.

House GOP leadership said they would not encourage members to vote for or against Democrats' impeachment push, according to House leadership aides, but to "vote their conscience."

In the Senate, Majority Leader Mitch McConnell has not said if he would vote to convict or whether he'd hold a trial in the Senate, ABC News has learned, but he has privately indicated he believes impeaching Trump could make it easier to rid the Republican Party of Trumpism.
