During his address Thursday, Biden announced his first joint session of Congress will take place next month, where he will address the second pillar of his recovery plan, focused on investments in infrastructure.

The president-elect praised Congress for working across the aisle to pass a COVID-19 relief bill in December, but reiterated his message that the package by itself was only a "down payment." He said more is required, framing his policy proposal as the next step and urging lawmakers to push forward.

After blasting the current administration's vaccine distribution plan as a "dismal failure," Biden previewed his remarks Friday, where he plans on laying out his vaccination plan.

"We'll have to move heaven and Earth to get more people vaccinated, to create more places for them to get vaccinated, to mobilize more medical teams to get shots in people's arms, to increase vaccine supply and to get it out the door as fast as possible," he said.

Sen. Bernie Sanders issued a statement in support of Biden's COVID Rescue Plan, calling it a "very strong first installment," hinting that he believes more should be done in the future. It could serve as an indication of how the plan will be received by the progressive wing of the Democratic Party.

"President-Elect Biden has put forth a very strong first installment of an emergency relief plan that will begin to provide desperately needed assistance to tens of millions of working families facing economic hardship during the pandemic," Sanders said Thursday in the statement.

"The president-elect's COVID-relief plan includes many initiatives that the American people want and need, including increasing the $600 direct payments to $2,000, and raising the minimum wage to $15 an hour," he added. "As the incoming Chairman of the Senate Budget Committee, I look forward to working with the president-elect and my colleagues in Congress to provide bold emergency relief to the American people as soon as possible."

Biden, in an evening address from Wilmington, Delaware, is announcing his vaccination and economic rescue legislative package.

The ambitious $1.9 trillion proposal focuses on stimulus amid the ongoing pandemic.

Biden's plan would dedicate more than $1 trillion of the $1.9 trillion price tag for direct stimulus, officials said, while $400 billion would go toward COVID-related projects, including the nationwide vaccination program, and $440 billion toward relief for communities and businesses.

The plan includes direct payments of up to $1,400 to families in need, that when combined with the recent $600 stimulus payment would deliver on Biden's pledge to pass $2,000 of direct payments, along with a $400 weekly unemployment insurance benefit through September and a child tax credit.

Photos show the beginning of the process to move President Donald Trump out of the White House, as workers load boxes on to trucks.

Aside from Trump's comments on the 25th Amendment, impeachment and last week's attack on the U.S. Capitol, the president's remarks alongside the border wall were notable in that he spoke -- both in tone and content -- as if he had accepted the end of his presidency was near.

His speech Tuesday reflected an attempt to spend one of his final days in office focused on highlighting what he believes are his accomplishments as president with his signature promise to build a wall among them.

Tump also warned that a "tidal wave" of undocumented immigrants would head toward the United States if his immigration policies are reversed.

"We can't let the next administration even think about taking it down," Trump said, referring to the barrier, although Biden has said he would not dismantle existing barrier -- just stop further construction.

"At this very moment, smugglers and coyotes are preparing to surge the border if our policies are loosened or removed," Trump said. However, Customs and Border Protection chief Mark Morgan told ABC News just a few weeks ago, "the in-flows [of immigrants at the border] have basically slowed to a trickle."
