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.

Five key Senate panels have now confirmed that they will hold confirmation hearings for Biden's top national security officials before Inauguration Day -- although it remains unlikely most of his picks will be confirmed by day one.

Avril Haines will have her hearing Friday to be Director of National Intelligence, while four others will have theirs on Tuesday -- Tony Blinken for secretary of state, Janet Yellen for Treasury secretary, Lloyd Austin for Defense secretary, and Alejandro Mayorkas for Homeland Security secretary.

The Senate Foreign Relations Committee hasn't scheduled a hearing yet for Linda Thomas-Greenfield, Biden's pick for U.N. ambassador and a member of his Cabinet, despite her being announced in November. Bill Burns, Biden's pick to be CIA director, also doesn't have a hearing scheduled yet, but Biden only announced his intention to nominate Burns Monday.

It's unclear how long after a confirmation hearing any of these Cabinet picks can be confirmed, especially with an impeachment trial -- but they'll require a committee vote and then a full Senate vote. It's likely most won't be confirmed and in position on Inauguration Day.

Biden's team has escalated pressure this week to confirm his national security Cabinet as soon as possible.

In contrast, on Trump's Inauguration Day, the Senate confirmed both John Kelly as Department of Homeland Security secretary and Jim Mattis as Department of Defense secretary, and 11 more Trump nominees already had their confirmation hearings. President Barack Obama had seven Cabinet chiefs confirmed on Inauguration Day, while six more had confirmation hearings by then and his Defense Secretary Bob Gates stayed on from the Bush administration, according to the U.S. Senate website.
