Acting Attorney General Jeffrey Rosen has issued an updated statement in response to Wednesday's [storming of the U.S. Capitol](], saying federal prosecutors have been working overnight to identify perpetrators to draw up charges when warranted, including on some who he says will be charged Thursday.

“Yesterday, our Nation watched in disbelief as a mob breached the Capitol Building and required federal and local law enforcement to help restore order. The Department of Justice is committed to ensuring that those responsible for this attack on our Government and the rule of law face the full consequences of their actions under the law," Rosen said in a statement, noting law enforcement officials are working with the public to gather evidence.

"Some participants in yesterday’s violence will be charged today, and we will continue to methodically assess evidence, charge crimes and make arrests in the coming days and weeks to ensure that those responsible are held accountable under the law," he added.

A law enforcement official confirms to ABC News that thus far at least a dozen individuals involved in Wednesday's violence are already expected to face charges and that list will grow significantly as more are identified.

Senate Minority Leader Chuck Schumer has called for the immediate removal of President Trump from office.

He said in a statement Thursday morning the "quickest and most effective" way to do this would be through use of the 25th Amendment but that if Vice President Mike Pence and the Cabinet don't act, Congress should reconvene to impeach the president.

“What happened at the U.S. Capitol yesterday was an insurrection against the United States, incited by the president. This president should not hold office one day longer," Schumer said in the statement.

“The quickest and most effective way - it can be done today - to remove this president from office would be for the Vice President to immediately invoke the 25th amendment. If the Vice President and the Cabinet refuse to stand up, Congress should reconvene to impeach the president," he said.

There have been discussions among some members of Trump's Cabinet and his allies over invoking the 25th Amendment, multiple sources with direct knowledge of the discussions told ABC News.

Facebook has taken the unprecedented step of indefinitely blocking Trump's account after removing a video and temporarily suspending his account amid eruptions of violence at the Capitol on Wednesday.

"We believe the risks of allowing the President to continue to use our service during this period are simply too great," Facebook CEO Mark Zuckerberg said in a post. "Therefore, we are extending the block we have placed on his Facebook and Instagram accounts indefinitely and for at least the next two weeks until the peaceful transition of power is complete."

As the world watched a pro-Trump mob storm the Capitol Wednesday, Trump shared a video on his social media accounts telling the group "we love you" and "you’re very special" while he told them to go home. The video was soon removed by Facebook, Twitter and YouTube, and as pressure mounted, Facebook and Twitter temporarily suspended Trump's accounts.

Another prominent former Republican leader has broken his silence on Trump and the Republican Party Thursday, with former House Speaker John Boehner calling for the GOP to "awaken" following Wednesday's "invasion" of the U.S. Capitol.

"I once said the party of Lincoln and Reagan is off taking a nap. The nap has become a nightmare for our nation. The GOP must awaken. The invasion of our Capitol by a mob, incited by lies from some entrusted with power, is a disgrace to all who sacrificed to build our Republic," Boehner said in a tweet.
