President-elect Joe Biden is moving forward with transition plans, capping a tumultuous and tension-filled campaign during a historic pandemic against President Donald Trump, who still refuses to concede the election two weeks after Biden was projected as the winner and is taking extraordinary moves to challenge the results.
Running out of legal alternatives to override the election loss, Trump invited Michigan's top Republican state lawmakers to visit the White House on Friday, as he and allies pursue a pressure campaign to overturn results in a state Biden won by more than 150,000 votes.
Despite Trump's roadblocks and his administration refusing to recognize Biden as the president-elect, Biden is forging ahead as he prepares to announce key Cabinet positions.
Though Trump has alleged widespread voter fraud, he and his campaign haven't been able to provide the evidence to substantiate their claims and the majority of their lawsuits have already resulted in unfavorable outcomes.

Michigan House speaker confirms he'll meet with Trump
Michigan House Speaker Lee Chatfield, among the Republican state lawmakers expected to meet with Trump , tweeted he "won't apologize" for accepting a meeting with the president, adding that he's honored to speak with him.
The White House meeting comes ahead of the Michigan board of canvassers convening on Monday to review and certify the state's electoral results.
Pence campaigns for Senate runoffs as balance of power hangs on Georgia
As the balance of power in the Senate -- and Biden's subsequent ability to pass the big-ticket legislation he's hoping for -- hangs on two election runoffs in Georgia, Republicans are rallying in the state to defend their majority in Washington.
Vice President Mike Pence touched down in Georgia Friday afternoon for two campaign events and was greeted by Gov. Brian Kemp and incumbent Sens. David Perdue and Kelly Loeffler upon his arrival. They all exchanged fist bumps while donning masks.
After exchanging pleasantries, Pence, Perdue and Loeffler posed together for the cameras.

Loeffler is facing a challenge from Rev. Raphael Warnock, senior pastor at the historic Ebenezer Baptist Church in Atlanta, while Purdue is facing Jon Ossoff, who nearly flipped Georgia’s 6th Congressional District for Democrats in a special election in 2017. If Democrats win both races, the Senate will be represented equally by the two parties, and Vice President-elect Kamala Harris will step in to break the tie on any votes.
Democrats see promise in the purple state as Biden beat Trump by more than 12,000 votes there, audit results confirmed Thursday.

Some Republicans put pressure on Trump to show evidence or allow transition to begin
A growing list of Republicans on Capitol Hill are putting pressure on Trump to allow the transition process to begin for Biden, giving him access to intelligence briefings and pandemic planning despite the president clinging to power.
Sen. Mitt Romney, a frequent Trump critic and the only Republican to vote to remove Trump from office in his impeachment trial, issued a strong rebuke late Thursday of the president’s move to invite Michigan lawmakers to the White House, saying, “It is difficult to imagine a worse, more undemocratic action by a sitting American President.”
Sen. Ben Sasse of Nebraska, another Republican who has publicly feuded with Trump, urged Americans to look at what the president’s legal team is saying in court, not during press conferences, “because there are legal consequences for lying to judges” preventing them from making unfounded claims of widespread fraud.
"No, obviously, Rudy and his buddies should not pressure electors to ignore their certification obligations under the statute," Sasse said in a statement late Thursday. "We are a nation of laws, not tweets."
In an interview with Fox News Radio Thursday, Joni Ernst, an Iowa Republican and ally of Trump's, also called the barrage of accusations from Trump’s lawyers “offensive” and “absolutely outrageous.”
And while retiring Republican Sen. Lamar Alexander is still unwilling to outright claim Biden won the election, he said in a statement Friday, "it looks like he has a very good chance” and that Biden should start receiving transition materials, which he said is particularly necessary in the coming months for vaccine distribution. On Thursday, he also told Know News, a Tennessee news outlet, he hasn't seen any evidence of widespread voter fraud.

Democrats have also ramped up their rhetoric with House Majority Leader Steny Hoyer telling Capitol Hill reporters he believes the president’s actions “border on treason” and that he is “undermining the very essence of democracy.”

House involvement in Biden transition possible, Pelosi says
During her press conference on Capitol Hill Friday morning, House Speaker Nancy Pelosi was asked if the House of Representatives will have an "expanded" role if Trump continues to derail the Biden transition and refuses to concede.
"Yes," Pelosi said. "I'm not one to show my hand, but nonetheless, we're ready. We're ready."

She did not elaborate any further on the potential involvement.
Pelosi also told reporters that she and Senate Minority Leader Chuck Schumer plan to discuss the lame duck session and urgency of COVID-19 relief with Biden and Vice President-elect Kamala Harris later this afternoon in Wilmington, Delaware.
