Senate Majority Leader Mitch McConnell’s office has confirmed the Senate will not return early for an impeachment trial.

The GOP leader spoke to Minority Leader Chuck Schumer and said he has no intention of invoking any emergency authority the leaders have to jointly call the Senate back.

That means the earliest the trial can start is  Jan. 19 -- the same day as the first confirmation hearing for one of Biden's Cabinet picks and one day before Biden's inauguration. It's unclear how those events might be affected as Trump is poised to be impeached in the House later Wednesday.

Rep. Jason Crow, D-Colo, a former Army Ranger with multiple combat deployments, called on his Republican colleagues to find the courage to vote to impeach Trump.

"Last week I stood in that gallery to defend this chamber against the violent mob called here by Donald Trump. I have dedicated my life to the defense of our nation and Donald Trump is a risk to all that I love," he said. "I'm not asking you to storm the beaches of Normandy, but show a fraction of the courage we ask of our troops every day. Leadership is hard. It's time to impeach."

Freshman progressive Rep. Cori Bush, D-Mo., who introduced a resolution on the House floor Monday seeking to expel lawmakers who still voted to overturn the election after the Capitol siege, was met with boos from Republicans after her remarks in which she called Trump "a white supremacist president."

"If we fail to remove a white supremacist president, who incited a white supremacist insurrection, it's communities like Missouri's 1st District that suffer the most," she said.

Rep. Maxine Waters, D-Calif., a staunch critic of Trump's, warned earlier, "He is capable of starting a Civil War."

Rep. Veronica Escobar, D-Texas, as with many Democrats before her, have called on Trump not only to be impeached but to "never be allowed to hold office again."

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.”

As procedural votes were underway in the House, Speaker Nancy Pelosi went outside the Capitol to thank the National Guard troops deployed to the complex in the wake of last week's riot and ahead of Biden's inauguration in one week.

Some National Guard members inside the Capitol were spotted taking in the sights of the Rotunda Wednesday morning, gathering around and listening to Rep. Brian Mast, R-Fla., an Army veteran who lost both legs in Afghanistan.

The Capitol has been closed to tours for months due to the coronavirus pandemic. With the exception of last Wednesday's attack, this is one of the few times visitors have snapped photos inside the building during the pandemic -- finding themselves with unique access as they've been designated to protect the building and lawmakers.

As lawmakers arrived on the Hill ahead of the House gaveling in to consider Trump's second impeachment, a heavy National Guard presence greeted them both outside and inside the building -- with some resting, embracing their rifles, on the floor of the Capitol.

Jane Campbell, the president and CEO of the United States Capitol Historical Society, confirmed to ABC News that troops have not been quartered in the Capitol since the Civil War -- when the Rotunda was still under construction, and the open-air space was used as a field hospital.

A Defense official said the National Guard members seen sleeping at the Capitol are on breaks and noted that it’s not uncommon on domestic or overseas deployments to see members taking breaks in between long shifts.

There are currently 6,600 members of the National Guard in Washington, D.C. with more continuing to flow in. A Defense official said Wednesday afternoon that the National Guard has now been authorized to have up to 20,000 Guardsmen in Washington for inauguration security and that most may be in town by this weekend.
