Congressional Democratic leaders commended Biden's announcement outlining his COVID-19 emergency relief proposal.

"The emergency relief framework announced by the incoming Biden-Harris Administration tonight is the right approach. It shows that Democrats will finally have a partner at the White House that understands the need to take swift action to address the needs of struggling communities," House Speaker Nancy Pelosi and Senate Minority Leader Chuck Schumer said in a statement.

"We will get right to work to turn President-elect Biden's vision into legislation that will pass both chambers and be signed into law," they added.

"The robust package announced by President-elect Biden and Vice President-elect Harris shows we now have the necessary leadership in the Executive Branch to turn this around and we are ready to get to work to deliver aid without delay," Pelosi and Schumer said.

Biden will propose a $1.9 trillion, “American Rescue Plan" to address the ongoing COVID-19 vaccination effort and immediate economic need to Americans in evening remarks, transition officials disclosed on a call with reporters Thursday.

According to officials on the call, the rescue policy is only one part of Biden’s overall policy, with a “recovery” phase expected to be introduced in February. They said Biden’s rescue policy will include three components: Tackling vaccine distribution, ramping up testing and getting kids back in school within the first 100 days of his administration; delivering $1,400 per-person direct stimulus checks and expanding unemployment benefits, including $400 weekly benefit through September on top of state benefits; and delivering aid to states and communities to support small businesses, addressing housing insecurity by expanding the eviction and foreclosure moratorium through Sept. 2021.

More than $1 trillion of the $1.9 trillion price tag will be used for direct stimulus, officials said, while $400 billion will go toward COVID-19-related projects, including the nationwide vaccination program, and $440 billion will go toward relief for communities and businesses.

Biden will also call for Congress to provide $350 billion for state local and territorial governments, an effort to keep essential workers on the job.

If enacted, it would be one of the largest and most expensive economic stimulus packages in U.S. history.

Ahead of Biden's inauguration and in the wake of last week's attack at the Capitol, the United States Capitol Police (USPS) has enhanced security measures across the Capitol Complex, including adding fencing and making several street closures until further notice, the agency announced Thursday.

"Be advised that the U.S. Capitol Complex is closed to the public, and the Capitol Grounds will not be accessible to the public on January 20, 2021.  Anyone attempting to unlawfully gain access to the Capitol Grounds by climbing a fence or any other unlawful means will be subject to an appropriate use of force and arrest," the USPS said in a statement.

Workers were seen installing barbed wire on security fencing surrounding the Capitol on Thursday afternoon as National Guard troops, some armed, patrolled the area. As National Guard troops continue flowing into the area, there are currently over 7,000 currently stationed in Washington with that number expected to grow to 20,000 over the weekend.

House Minority Leader Kevin McCarthy, R-Calif., does not support efforts to remove Rep. Liz Cheney, R-Wyo, as House GOP conference chair and a member of House GOP leadership, a McCarthy spokesman told ABC News. This comes after some conservative House Republicans called on her to step down following her announcement that she supported impeaching Trump.

The Wyoming Republican and daughter of former Vice President Dick Cheney is the highest-ranking woman in Republican leadership 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-Arizona, said Tuesday.

On Wednesday night she joined nine other House Republicans in breaking from the party and voting to impeach Trump for his role in last week's riot at the Capitol.

The House Rules Committee is in recess for a meeting to tee up a resolution that will be voted on the House floor later Tuesday which seeks to pressure Vice President Mike Pence to invoke the 25th Amendment and remove Trump from office.

While Pence has not indicated publicly what he intends to do, and it's not expected he will take action -- making the resolution's expected passage largely symbolic -- House Democrats will go forth in considering a single article of impeachment Wednesday.

Democrats in the committee rehashed painful, devastating memories to highlight their concerns and rage and exasperation, explaining why they want to make sure Trump is held fully accountable for inciting the riot.

Rep. Jamie Raskin, D-Md,, said he was there with his daughter and son-in-law. His family showed up to support him just one day after burying Raskin's son.

"This is not just a crisis and an emergency. It is a continuing crisis and emergency. It is not over yet," Raskin said. "Can we say that we feel safe being in the hands of this president, with the horror and the threats returning to our nation's Capitol?"

Rep. Norma Torres, D-Calif., described cowering in the House chamber. Hiding under her chair, struggling to put on an escape hood, she called her daughter, telling her, "I'm running for my life" before quickly hanging up.

"Trump incited this attack and there should be no question as to what Vice President Pence needs to do right now," she said. "I heard the shots being fired. I saw the smoke from the tear gas being been deployed. And I watched one officer with no equipment face a raging mob just outside the chamber. We crawled across the entire length of that balcony."

Democrats repeatedly implored Republicans to admit the election was fair and free, and Republicans scolded Democrats for, they say, seeking to divide the country further with a second impeachment.
