In Delaware on Tuesday, President-elect Joe Biden criticized the Trump administration on their handling of distributing COVID-19 vaccines.

Biden said the current administration is falling way behind when it comes to distributing vaccines. "It is not progressing as it should," Biden said.

Biden said Trump promised 20 million Americans would be vaccinated by the end of December, but only 2 million have received the first dose. Biden added that it would take years, not months, for all Americans to get vaccinated at the current rate.

WATCH RECAP:

Biden said he aims to distribute 100 million vaccine shots in his initial 100 days in office, adding that the current vaccination effort would need to be up five to six times to reach his goal of one million shots a day.

"I'm going to move heaven and earth to get us going in the right direction," the President-elect said, noting he would also use the Defense Production Act to boost the production of materials for COVID vaccines.

"We're going to get through this. Brighter days are coming, but it's going to take all the grit and determination we have as Americans to get it done," Biden said. "We need to be honest: The next few weeks and months are going to be very tough, very tough for our nation. Maybe the toughest during this entire pandemic."

Biden added that in his first 100 days, there would be a federal mask mandate on federal properties, but states and individuals would have to be part of the solution.

After pointing out former New Jersey Governor Chris Christie's shifting his stance on masks, Biden called on President Trump to "clearly and unambiguously" promote mask-wearing and the vaccine during his final weeks in office.

"Look, my ability to change the direction this pandemic starts in three weeks, with thousands dying every day between now and then," Biden said. "If we just step up together, wear masks, socially distance, wash our hands, avoid large indoor gatherings ― I know all these are not easy to ask. But I'm asking you to make a sacrifice. You're already making tremendous sacrifices every single day."

The Presidential Inaugural Committee formed by President-elect Joe Biden announced this week that among the inaugural events will be a memorial for the lives lost due to the coronavirus.

The memorial is scheduled to be held January 19 at 5:30 p.m. ET, one might before Biden and Vice President-elect Kamala Harris will take the oath of office. The Presidential Inaugural Committee is calling on cities to join by ringing church bells in a “national moment of unity and remembrance.”

The event in D.C. will include a lighting around the Lincoln Memorial Reflecting Pool.

“The inauguration of President-elect Joe Biden and Vice President-elect Kamala Harris represents the beginning of a new national journey. However, in the midst of a pandemic – when so many Americans are grieving the loss of family, friends, and neighbors – it is important that we honor those who have died, reflect on what has been one of the more challenging periods in the nation’s history, and renew our commitment to coming together to end the pandemic and rebuild our nation,” said PIC Communications Director Pili Tobar.

As of Friday, more there have been more than 347,000 coronavirus-related deaths in the US.

This year’s presidential inauguration will look different than in years past. Biden has said he doesn’t expect there to be a large gathering, and his campaign has encouraged supporters to stay home in order not to spread the virus.

The quadrennial inauguration of a president and vice president is typically attended by hundreds of thousands. The committee says in light of the pandemic, a large gathering should be avoided.

"Our goal is to create an inauguration that keeps people safe, honors the grand traditions of the Presidency, and showcases the Biden-Harris Administration’s renewed American vision for an inclusive, equitable, and unified citizenry,” said PIC CEO Tony Allen in a statement.

While the organizers did not say the inauguration parade would be canceled, organizers said it would be “re-imagined.”

Other Inauguration Day events, such as the signing ceremony and luncheon the new president has with congressional leaders, are still unknown.
