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.

Biden has announced a new slate of nominations and staff at the Department of State. Many of the picks have ties to both Biden and former President Barack Obama.

The picks are:

-Wendy R. Sherman: Deputy secretary of state

-Brian P. McKeon: Deputy secretary for management and resources

-Bonnie Jenkins: Under secretary for arms control and international security affairs

-Victoria Nuland: Under secretary for political affairs

-Uzra Zeya: Under secretary for civilian security, democracy, and human rights

In a statement, the Biden transition team said these key nominations will help "build back better at the State Department, renew and reimagine American leadership to keep us safe at home and abroad, and address the defining challenges of our time — from infectious disease, to terrorism, China, nuclear proliferation, cyber threats, and climate change. They will put into practice the President-elect and Secretary-designate’s vision of a foreign policy that promotes America’s security, prosperity, and values, and delivers for the middle class."
