The House of Representatives has voted to impeach President Trump -- making Trump the only president in American history to be impeached twice.

Ten Republicans have sided with Democrats in the ongoing vote for impeachment with the count currently standing at 225-194.

217 votes were needed to impeach the president.

House lawmakers charged Trump with one article of impeachment for "incitement of insurrection" citing his role in the Jan. 6 attack on the U.S. Capitol.

While House Speaker Nancy Pelosi has declined to yet say publicly when the House will send the article over to the Senate, a source involved in the Democratic leadership deliberations told ABC News earlier Wednesday Pelosi plans to send the article to the Senate next week.

Senate Majority Leader Mitch McConnell's office confirmed earlier in the day that the Senate will not return early for an impeachment trial, so the earliest the trial could start is Jan. 19 -- a day before Biden's inauguration.

Republican Rep. Peter Meijer of Michigan is the seventh House Republican to announce he will vote to impeach Trump, announcing his intention in a statement posted to Twitter moments before voting got underway.

"President Trump betrayed his oath of office by seeking to undermine our constitutional process, and he bears responsibility for inciting the insurrection we suffered last week. With a heavy heart, I will vote to impeach President Donald J. Trump," he said in a tweet, attaching a longer statement.

Meijer joins Republican Reps. John Katko, N.Y., Liz Cheney, Wyo., Adam Kinzinger, Ill., Fred Upton, Mich., Jaime Herrera Beutler, Wash., and Dan Newhouse, Wash, in saying he will vote to impeach the president.

No House Republicans voted to impeach Trump in 2019.

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."

The FBI, DHS, Secret Service and U.S. Capitol Police, along with several local law enforcement agencies, have issued an extensive "threat assessment" surrounding Wednesday's inauguration.

It covers a range of threats surrounding the inauguration, including not only physical threats from domestic terrorists but also influence campaigns from Russia, China and Iran stemming from the Capitol siege. It even covers physical threats from drones.

The memo says domestic extremists is the “most likely” threat to the inauguration, citing recent incidents of ideologically motivated violence, including the deadly mob at the U.S. Capitol building.

Regarding foreign concerns, the assessment said that since the incident at the Capitol, “Russian, Iranian, and Chinese influence actors have seized the opportunity to amplify narratives in furtherance of their policy interest amid the presidential transition.”

“We have not identified any specific, credible information indicating that these actors intend to explicitly commit violence,” it added. “Furthermore, we have not identified any specific, credible cyber threat to critical infrastructure supporting the upcoming Presidential Inauguration nor a specific credible cyber threat to military or law enforcement personnel supporting the event."

The memo did say, however, that Russian state media has “amplified themes related to the violent and chaotic nature of the Capitol Hill incident, impeachment of President Trump, and social media censorship.”

Iranian state media has “continued to stoke claims that President Trump encouraged and incited the violence, as well as calls to invoke the 25th amendment,” the memo added. It has also “amplified perceived concerns related to President Trump’s mental health and the prospect of other risky actions he could take before leaving office.”

Finally, it noted that Chinese media has “seized the story to denigrate US democratic governance -- casting the United States as broadly in decline -- and to justify China’s crackdown on protestors in Hong Kong."

Lastly, the memo warned that drones could disrupt law enforcement operations at the inauguration, though it added that it does not have “specific, credible information” indicating malicious actors have plans to use unmanned aircraft systems to target the event.
