As part of rule debate leading up to debate on the article of impeachment, Republicans have largely focused on procedural concerns, criticizing Democrats for moving quickly to impeach Trump without a full investigation and suggesting the move would further divide Americans.

"I hold him accountable for the attack on the Capitol," newly elected Rep. Nancy Mace, R-S.C., said, making her first speech on the House floor.

"If we're serious about healing the divisions in this country, Republicans and Democrats need to recognize that last week wasn't the first day of violence," she continued. "There is violence on both sides of the aisle."

"President Trump will leave office in seven days," Rep. Jason Smith, R-MO, said. "This is a reckless impeachment ... have a conscience."

Rep. Jim Jordan, R-Ohio, attacked Democrat Rep. Jim McGovern, the chairman of the House Rules Committee, over his 2017 objection to the election results, and accused Democrats of hypocrisy.

McGovern quickly shot back that Democrats and Hillary Clinton recognized Trump's victory -- when Republicans refused to acknowledge Biden's.

"The bottom line is this. This Capitol was stormed -- people died because of the big lies that were being told by this president and by too many other people on this side of the aisle. Enough!" McGovern said. "Coming up on this floor and talking about whataboutism and trying to make these false equivalences -- give me a break."

"The president of the United States instigated an attempted coup in this country," he added. "If this is not an impeachable offense I don't know what the hell is."

Several conservative House Republicans have criticized Rep. Liz Cheney since she announced she would support impeachment Tuesday evening.

The Wyoming Republican is the chair of the House GOP conference -- the No. 3 leadership position -- and was reelected to by GOP members at the start of this Congress.

"We ought to have a second vote," Rep. Jim Jordan, R-Ohio, told reporters Wednesday about the leadership position. "The conference ought to vote on that."

"She should not be serving this conference," Rep. Andy Biggs, R-Ariz., said Tuesday.

It's unclear how widespread the effort to remove Cheney from GOP leadership is. But Trump's top allies in the House are using impeachment as an opportunity to kneecap Cheney, a potential future speaker, after months of simmering tensions.

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."

While House Democrats take action to remove Trump from office after he encouraged supporters to march on Capitol Hill last week.

Trump on Monday plans to award the Presidential Medal of Freedom -- the nation's highest civilian honor -- to GOP Rep. Jim Jordan of Ohio, his longtime defender, in a closed event, something not the event not mentioned on his schedule, a White House official said. Later in the week, he's expected to bestow the same honor on New England Patriots head coach Bill Belichick.

Sources told ABC News over the weekend the White House is building out a week of programming to highlight Trump’s record over the dwindling days of his administration, despite amplified calls for Trump to resign or risk facing a second impeachment. Appearing to dismiss those calls, Trump has a trip planned for Tuesday to Texas to showcase the border wall he's pushed hard for, and is expected to host events in the next week to highlight what sources say are the administration's achievements in areas including foreign affairs, business and pandemic response.

The president was angry for much of this past weekend -- mostly about Twitter permanently suspending his account on Friday, according to sources who have spoken directly to Trump. Sources said the president is expected to depart Washington before Biden takes the oath of office on Jan. 20.

While Biden said last week it’s a "good thing" Trump isn’t attending his inauguration, he hasn’t said whether he supports impeaching Trump, deflecting that decision to Congress instead. Biden's said he wants the incoming Congress to focus on his Cabinet nominations and pandemic relief from the onset, but an impeachment trial in the Senate risks preempting the rest of its business.

On Monday, Biden is slated to meet with transition and economic advisors and will publicly receive the second dose of the COVID-19 vaccine from Wilmington, Delaware, in the afternoon.
