As of Thursday afternoon, the balance of power in the House and Senate was still up in the air. Democrats could lose majority control of both chambers.

"The American people sent a message that they want us to work together," Biden said.

"Folks, I'll always welcome any good ideas, whether it's Democrat or Republican, to move the country forward," Biden said, before going on to list potential legislative efforts by a GOP majority that he would block.

"But I've also made it really clear that Republicans tried to repeal the power we just gave Medicare to reduce prescription costs, I will veto it," he said. "If Republicans try to walk away from the historic commitment we just made to deal with the climate crisis, I will not let that happen. If Republicans try to cut Social Security or Medicare, I will not let that happen."

In Clark County, Nevada, 50,000 ballots still need to be counted, according to county registrar of voters Joe Gloria.

“Over the course of the next three days we'll get them into the system,” he said.

“We will report again Friday night and then report again Saturday night. At that point we expect the majority of the ballots to be tabulated,” he said.

“As we gather here, votes are still being counted. But it is clear your work sent a message to the entire world: Our democracy is intact,” Harris said.

“And when democracy is intact, this is what it looks like,” she continued. “Here's the thing: some Democrats won and some Republicans won. That is what happens when more than 100 million Americans participate and vote in free and fair and open elections.”

Harris, President Joe Biden, first lady Jill Biden and second gentleman Douglas Emhoff were all in attendance. The event took place at the Howard Theater in Washington, D.C.

“You did it, Joe,” Harris said, riffing off her viral video reacting to the 2020 election results.

Maricopa County Board of Supervisors Chair Bill Gates told ABC News he expects to wrap up vote counting in Arizona’s largest county by Monday.

“We have just a little over 400,000 votes left to be counted,” he said.

A record number of "late earlies" were dropped off on Election Day -- 290,000 ballots -- which is slowing the process, Gates added.

“This is not out of the ordinary -- it's fairly consistent with what we've done in the past,” he stressed. “Again, we want to be doing this accurately.”
