Trump is heading back to Washington, D.C. from his Mar-a-Lago resort in Florida Thursday morning, a day ahead of schedule -- missing his annual lavish New Year's Eve party.

He had always planned to return ahead of Wednesday's joint session of Congress where the Electoral College votes are certified but now will also be in the capital for New Year's Eve. It's unclear why he changed his plans, and the White House provided no comment.

Meanwhile, the The Presidential Inaugural Committee has announced that on the eve of the Biden inauguration it will host a "memorial to remember and honor the lives lost to COVID-19 in cities and towns across the country.”

The portion of the ceremony that takes place in Washington will include lighting around the Lincoln Memorial Reflecting Pool. "It will be the first-ever lighting around the Reflecting Pool to memorialize American lives lost," according to the committee.

In the Senate, relief payments continue to be front and center even after Senate Majority Leader Mitch McConnell seemed to slam the door on voting exclusively on the $2,000 relief payments Wednesday.

Sen. Bernie Sanders and others may still try -- likely without success -- to force his hand by continuing to object to the Senate voting on the defense bill veto override alone. The Senate is expected to vote to end debate by Friday, bringing the vote to override the veto as late as Saturday and keeping lawmakers in Washington over the New Year holiday.

For his part, McConnell, who said that relief checks were for Democrats’ “rich friends who don’t need the help," plans to try to couple the $2,000 relief payments with other issues Trump has demanded Congress act on, including eliminating protections for tech companies and investigating baseless claims of election fraud. The strategy will likely serve as "poison pills" for Democrats, who won’t vote for it.

In the end, those $2,000 checks are not expected to be approved with most Republicans standing in the way, but Congress is expected to override Trump’s veto of the defense measure -- the first veto override of Trump's presidency. Taken together, the two actions amount to a very rare bucking of this president by members of his own party.

In a media availability at the Georgia State Capitol in Atlanta this afternoon, Gov. Brian Kemp responded to the president saying he should resign via Twitter Wednesday morning.

When first asked about the president's tweet, Kemp said he was focused on the coronavirus -- ensuring there are enough hospital beds and getting the vaccine distributed and administered across the state.

When pressed on Trump's call for him to resign, Kemp said, "I've supported the president. I've said that many times. I've worked as hard as anybody in the state on his reelection up through November the 3rd."

"I've supported the legal process that him or any other campaign can go through in that state, but at the end of the day, I also have to follow the laws in the Constitution," he added.

A coalition of 46 left-leaning groups including Greenpeace, Service Employees International Union (SEIU), MoveOn has issued a new letter calling on Biden and Vice President-elect Harris to focus on “democracy reform policies.”

The coalition is urging the Biden-Harris Administration to sign “a robust ethics order for your appointments on day one of your administration to prevent conflicts of interest, undue lobbyist influence, and ensure transparency to guarantee that your administration is focused solely on working for all Americans.”

Some of the demands from the groups include protecting voting rights, ending the power of big money in politics, restoring ethics and accountability in the capital, and protecting the rule of law through checks and balances.

President Trump's personal attorney, Rudy Giuliani, spoke before members of the Georgia state Senate and repeated his baseless claims of widespread voter fraud and the fantasy that his client won the state of Georgia and the general election altogether. No lawmaker asked him a question following his remarks.

The hearing, which Trump tweeted was being broadcast on Newsmax and OANN this morning, was before the Senate Judiciary Subcommittee on Election Law -- the same subcommittee that Giuliani spoke before on Dec. 3, right before he was diagnosed with coronavirus.

Biden took aim at Trump in remarks following a briefing on national security and foreign policy, slamming the current administration for failing to fully cooperate with his agency review teams during the transition -- which Biden argued could leave the country vulnerable.

While commending his own agency review teams for their hard work amid a transition that was already made more challenging by COVID-19, Biden pointedly called out Department of Defense and White House Office of Budget and Management political appointees for, he said, not cooperating for a smooth transition.

"And the truth is many of the agencies that are critical to our security have incurred enormous damage. Many of them have been hollowed out in personnel, capacity and in morale," Biden added.

Later in his remarks, Biden stressed the need for cooperation during the transition, noting that it is a matter of national security to ensure there are no gaps that adversaries can seek to exploit when he takes office.

"We need full visibility into the budget planning under way at the Defense Department and other agencies in order to avoid any window of confusion or catch-up that our adversaries may try to exploit," Biden said. "Right now, we just aren't getting all the information that we need from the outgoing administration in key national security areas. It's nothing short, in my view, of irresponsibility."

Biden said other "Day One" challenges discussed in the briefing will draw on the skill sets of the Department of Homeland Security and the Federal Emergency Management Agency as they aim to "clean up the humanitarian disaster that the Trump administration has systematically created on our Southern border."

"We will institute humane and orderly responses. That means rebuilding the capacity we need to safely and quickly process asylum seekers, without creating near-term crises in the midst of this deadly pandemic," Biden said.

As he exited the stage at the Queen Theater in Wilmington, Delaware, Biden was asked if he supports the measure for $2,000 direct payments to Americans for COVID-19 relief, which the House will soon vote on. He responded with one word: "Yes."
