“It's easier to scale back than scale up, and we're going to be talking to people this week about that very topic and hope that the person who's sworn in on inaugural day sees it as a great day even though what happens at the Capitol is up to the Congress to decide.”

The senator — who said the process still needs to play out before it can be determined that Joe Biden defeated President Donald Trump — said that ceremony will be a time for Americans to see “how democracy works.”

“The president-elect is our guest that day, and once again I think we're going to project to the world that democracy works, that this country where — with the president's efforts and other efforts — incredible energy in this election produced a result,“ he said, adding: “This is a great time for us to show how a true democracy works,” he said.

But former FDA commissioner Scott Gottlieb expressed caution about having a large crowd at the inauguration on CBS’ “Face the Nation.”

“We're going to be right in the thick of probably the worst point of this epidemic wave that we're going through right now,” he said. “And the Biden campaign, the Biden team, have shown that they're willing to forgo the usual trappings of running for office, so that they don’t expose people unnecessarily. I suspect they're going to take a similar approach to how they handle the inauguration.”
