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.

Senate Majority Leader Mitch McConnell effectively shut the door on allowing a vote on a bill that would boost pandemic relief checks from $600 to $2,000.

Republicans like McConnell have previously said they are concerned about the half-trillion-dollar price tag of the $2,000 payments that would add to the national debt.

On the Senate floor Wednesday, McConnell attacked House Democrats for wanting to send a "boatload of cash" to people making six figures who aren't in need, saying it doesn't make sense to support Americans who haven't lost income due to the pandemic.

"The Senate's not going to be bullied into rushing out more borrowed money into the hands of Democrats' rich friends who don't need the help," McConnell said.

He said Congress needs to send "smart targeted aid. Not another firehose of money."

McConnell also said he will not split the $2,000 relief payment bill from a repeal of Section 230 or the creation of an election fraud commission.

"The Senate is not going to split apart the three issues that President Trump linked together," McConnell said, which means the bill, if the Senate does intend to vote on it, is unlikely to ever become law.

Democratic Leader Chuck Schumer tried again Wednesday to unanimously pass the House standalone bill that swaps out the $600 payments for $2,000, but McConnell objected. Sen. Bernie Sanders, I-Vt., also tried to pass the House bill unanimously, but GOP Sen. Pat Toomey objected.

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."
