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.

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.
