The House has concluded debate on the second impeachment of Trump for "incitement of insurrection." The vote is now underway and is expected to take 40 minutes to one hour.

House Democrats are expected to vote to impeach the president. Seven Republicans have announced that they also plan to vote to impeach.

The House needs a simple majority to impeach the president.

Rep. Steve Scalise, R-La. -- the No. 2 Republican in the House -- was the last to speak for the Republican Party, said he opposed the "rushed" impeachment, and emphasized that the Senate will only be able to take up the trial once Trump is out of office.

"I've seen the dark evil of political violence firsthand. And it needs to stop. But all of us need to be unequivocal in calling it out every single time we see it, not just when it comes from the other side of the aisle," he said.

Invoking President Abraham Lincoln, he closed by calling on Americans to unify and "seek higher ground."

House Judiciary Chairman Rep. Jerry Nadler, D-N.Y., quickly responded to his remarks, saying, "We can have all this, and we can have accountability too," before handing off to Majority Leader Rep. Steny Hoyer, D-Md.

Hoyer, in a scathing rebuke of the president, repeated the words of Rep. Liz Cheney and called on his Republicans colleagues to rise to the moment and join her to "reject the vices we abhore."

"It is the first and only physical presence other than the 9/11 attack on this nation -- which came from abroad with a plane aimed at our Capitol dome. This attack was not from abroad. It was as Liz Cheney said, summoned, assembled, and inflamed by the president of the United States of America," he said.

"Last Wednesday, on Jan. 6, the nation and the world watched it shatter to pieces. There could be no mistaking any longer the kind of man sitting in the Oval Office or his intentions and capabilities. The curtain has been pulled back. The office to which he was elected could not temper or reform him," Hoyer said.

"Reject deceit. Reject fear mongering. Reject sedition, tyranny and insurrection," Hoyer said. "Reject one man over fidelity to one's country."

Hoyer noted that soon the House Reading Clerk will call the roll for voting, and added, "Make no mistake, this will be no ordinary roll call."

"These votes will be inscribed on the roll of history -- a record of courage -- and of our commitment to country and Constitution, of our commitment to the rule of law and renewal of that which we inherited and hope to pass on, unbroken, unshattered," he said. "Vote for this -- for America, for our constitution, for democracy, for history."

Senate Majority Leader Mitch McConnell sent a note to Republican colleagues Wednesday afternoon, as the House debated the expected impeachment of President Trump, stating that he has not made a final decision on how he would vote in an impeachment trial.

“While the press has been full of speculation, I have not made a final decision on how I will vote and I intend to listen to the legal arguments when they are presented to the Senate," said the note McConnell's team passed along.

The message comes after 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.”

At least six House Republicans -- including No. 3 Rep. Liz Cheney -- have announced they will vote to impeach the president.

Following several Republicans who aired their grievances with a "rushed" process, Rep. Chip Roy, R-Texas, condemned Trump for pressing Vice President Mike Pence to overturn the election but argued he couldn't support the impeachment article as written.

"Let us condemn which must be condemned but do it the right way with deliberation and without disastrous side effects. We must end tearing apart our nation by social media and sound bite," Roy said.

Another Texas Republican, Rep. Jodey Arrington, expressed some discontent at the president's rhetoric but suggested it would set a dangerous precedent to pin the actions of his supporters at the Capitol on the president.

"I'm not saying that the president didn't exercise poor judgment, but to criminalize political speech by blaming lawless acts on the president's rhetoric is wrong and a very dangerous precedent," he said to groans from Democrats. "The criminals who stormed the Capitol that day acted on their own volition. They are responsible. This is an important moment for our nation. We have to come together."

While other Republicans didn't go so far as to directly condemn Trump, they all condemned the violence at the Capitol -- but argued it was time for unity and healing, instead of an impeachment with one week until Biden's inauguration.

Democrats, however, rejected that stance.

"A police officer was killed. And what I hear from the other side is that it's time to heal? He's not even buried yet!" Rep. Donald Norcross, D-N.J., scolded his colleagues.

"If he has four years or four days, we must do the right thing for all Americans because he must be held accountable," he added.

Republicans argued there had been no hearings or witnesses called in the Judiciary Committee, to which Democrats responded that the lawmakers themselves witnessed the violence and immediate action must be taken to avoid further threats.

Virginia Rep. Abigail Spanberger called it “a point of sadness” after she joined her fellow Democrats and some Republicans Wednesday to vote to impeach Trump.

“Impeachment is necessary at this point in time because we have to make a clear statement that the incitement of an insurrection by a sitting U.S. president is absolutely unacceptable,” she told ABC's “Nightline.”

She acknowledged how close the president is to the end of his term, but said it’s still necessary to impeach Trump because it’s an “issue of accountability.”

“It’s an issue of law and order. It is an issue of ensuring that every person who holds this office in the future recognizes and knows and understands that in the United States of America, under no circumstances do we accept that the president … would incite a violent mob to insurrection for the purpose of holding onto power. It’s unacceptable, and generations into the future need to know that we believe that to be the case.”

The Democratic congresswoman has served Virginia’s 7th Congressional District since 2019. She said that the riot at the U.S. Capitol building last week during a joint session of Congress was “unimaginable.”

Spanberger also said it’s “ridiculous” to compare the Capitol insurgence to last year’s Black Lives Matter protests like some House Republicans did Wednesday.

“I have categorically denounced violence in all its forms, in any circumstance,” she said. “But this wasn’t violence. This was a domestic terrorist attack perpetrated by insurrectionists who lowered the flag of the United States and raised a flag with one man’s name on it.”

“It couldn’t be more different,” she added, “and false equivalencies are deeply saddening and disheartening, particularly for those of us who have sworn an oath to uphold the Constitution from all enemies, foreign and domestic.”
