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.

Trump, again with no public events, sends first tweet of day
In his first tweet of the day, Trump this afternoon said he's "reversed the ridiculous decision to cancel Wreaths Across America at Arlington National Cemetery" -- an annual program which had been canceled this year due to the coronavirus.
The president's tweet comes after the secretary of the Army said he had directed Arlington National Cemetery to safely host the event.
On any other day, Trump's tweets might number in the double digits by the late afternoon, but Trump has been uncharacteristically silent since the election, holding just three events open to White House press in the last two weeks and not taking any questions.

The tweet breaking his silence also came hours after his acting Secretary of Defense announced that the military will carry out the president's order to draw down troops in Afghanistan and Iraq before he leaves office.
Trump has not publicly weighed in on the highly-consequential decision.

Pennsylvania Supreme Court rules against the Trump campaign
The Pennsylvania Supreme Court has ruled against the Trump campaign in a case centered on whether election officials provided campaign observers “meaningful” access to monitor the counting of mail-in ballots.
The court, on a vote of 5-2, found that election officials followed the law in providing the Trump campaign sufficient access to the opening of mail-in ballots. There are simply no requirements that say how close the observers need to be placed to watch the process, the court found.
“These provisions do not set a minimum distance” for observers to watch the process, Justice Debra Todd wrote for the majority. “The General Assembly, had it so desired, could have easily established such parameters; however, it did not.”
And even those dissentingwere not partial to the Trump campaign's argument. In his dissenting opinion, Chief Justice Thomas G. Saylor wrote that the campaign’s request to cancel large numbers of ballots “based on isolated procedural irregularities” was “misguided.”
“I fail to see that there is any real issue,” Saylor wrote.

Harris on Capitol Hill as Biden participated in national security briefing
Vice President-elect Kamala Harris made a rare appearance on Capitol Hill Tuesday to cast the tie-breaking vote against allowing the Senate to proceed to a final confirmation vote for a Trump nominee to the Federal Reserve board of governors -- a tie that arose after two GOP Senators were exposed to COVID-19 and entered isolation this week.
Had Harris instead gone to Wilmington for a national security briefing with Biden, Vice President Mike Pence would likely have broken the tie in favor of Trump's nominee. But with Harris' intervention, Democrats squashed Senate Majority Leader Mitch McConnell's efforts to move ahead with confirming Judy Shelton.

The procedural vote failed with 50 nays to 47 yays. This count reflects McConnell voting "no" -- a move that allows him to bring the nomination back up for consideration at a later date.
Ahead of the procedural vote, Harris shared a fist-bump with Republican Sen. Lindsey Graham, who has been actively working to challenge Biden's position as president-elect.
It's Harris' first visit to the hill since the presidential election.

Biden briefed by slate of outside advisers on national security
Biden received a national security briefing in Wilmington, Delaware, from a slate of former government advisers and outside experts Tuesday afternoon as he awaits the Trump administration's ascertainment that will allow him to receive the Presidential Daily Brief and intelligence briefings usually given to a president-elect.
“I used to say, 'the next president of the United States,' -- when I was trying to get the nomination -- ‘whoever he or she will be is going to inherit a divided country, and a world in disarray,'" Biden began. "I wish I had been wrong."

"But, that's why I need you all so badly, and your advice. And to answer these twin challenges, we're going to need to reinvigorate our democracy at home, strengthen the coalitions of democracies we stand with and equip the American people to compete and succeed with a foreign policy that reflects their values and their needs,” Biden told the participants on a large screen via Zoom.
Several high-profile experts appeared at the briefing including former Obama administration National Security Adviser Tony Blinken, Gen. Stanley McChrystal, Adm. William McRaven, former U.N. Ambassador Samantha Powers and Avril Haines, a member of Biden’s transition team who he arrived with to the meeting.
Biden spoke briefly about the growing list of heads of states that he has connected with as president-elect, saying he believed he was up to 13 calls. He noted the enthusiastic reception he’s been receiving, stressing it has less to do with him and more to do with the "circumstances."

“I’m not being critical, just stating the obvious. You know that I've been unable to get the briefings that ordinarily would have come by now," Biden said, in thanking the participants for their advice.
