Vice President-elect and California Sen. Kamala Harris arrived on Capitol Hill Friday morning ahead of the Senate’s midnight deadline to pass a one-week continuing resolution on a government funding bill to prevent a shutdown.

“I’m here to vote,” Harris told reporters as she entered the building.

Harris is expected to vote to break the filibuster on the National Defense Authorization Act, an annual military budget bill, which Trump has twice threatened to veto.

Harris was last on the Hill on Nov. 17 to vote against a Trump nominee to the Federal Reserve Board of Governors.

The Trump presidency is now destined to end with falsehoods -- a blizzard of baseless accusations about the election that he lost, as distilled into a final plea to the Supreme Court.

Trump's ask is for the nation's highest court to overturn the results of the election. As unlikely as he is to succeed, that breathtaking statement doesn't even encapsulate the principles at stake that will matter long after Biden is inaugurated.

Some 106 House Republicans -- more than half the GOP conference -- are backing the president's effort to get the Supreme Court to step in. More than that number continue to resist labeling Biden "president-elect," just three days before the Electoral College will cement Biden's victory based on certified results from every state.

So much of the Trump era is ephemeral and transactional. Some Trump loyalists will essentially pretend as if Trump never existed, or that his smashing of conservative principles in service to Trumpism wasn't what it was.

But some of those principles -- of federalism, the rule of law and even basic democracy and common sense -- are still at stake at this moment.

Trump once famously promised to his supporters that they would be "sick and tired of winning" one day. Now, though, what Trump is losing could outlast the limited days of his presidency.

While Trump waits to hear whether the Supreme Court will take up Texas' case seeking to overturn and invalidate the votes of millions of Americans in four battleground states, he's continuing his pressure campaign on the high court Friday morning, calling on justices to “do what everybody knows has to do be done.”

Experts say justices are unlikely to take up the case, but the Texas lawsuit has quickly become a loyalty test for Republicans with 106 representatives -- about one-fourth of the House or half of the Republican caucus -- asking the high court to disregard millions of votes in a democratic election.

Trump also voiced his resistance Friday morning to turning over distribution of coronavirus vaccines to the incoming Biden administration, tweeting "they want to come in and take over one of the ‘greatest and fastest medical miracles in modern day history'" and slamming the Federal Drug Administration as a "big, old, slow, turtle" moments after Health and Human Services Secretary Alex Azar told ABC's "Good Morning America" that emergency authorization use of Pfizer's coronavirus vaccine is imminent and vaccinations could start as early as Monday. Trump's tweet follows months of him pressuring the agency to speed up its process for approving vaccinations.

Meanwhile, as the Biden White House takes shape, the president-elect is turning to familiar faces in former Obama administration officials to fill top posts and will be introducing some of those picks from Wilmington, Delaware, Friday afternoon.

His latest additions include tapping Dennis McDonough, former President Barack Obama’s chief of staff, as his nominee for secretary of veterans affairs, and naming Susan Rice, Obama’s former national security adviser, as the director of his White House Domestic Policy Council. These picks have some Democrats worried that with the resurgence of so many Obama-era officials there's little room for rising stars in the party.

In another historic first for the Biden team, the president-elect and Vice-President-elect Kamala Harris were named as Time’s 2020 "Person of the Year" -- the first time a vice president has been given the title.

Four states sued by Texas in a bid to overturn the results of the 2020 presidential election have asked the U.S. Supreme Court to swiftly reject the case and avoid legitimizing "a cacophony of bogus claims" that would upend the will of millions of American voters.

In court filings Thursday afternoon, the attorneys general of Pennsylvania, Wisconsin, Michigan and Georgia were scathing in their rebuttal to Texas' suit.

"The Court should not abide this seditious abuse of the judicial process," said Pennsylvania Attorney General Josh Shapiro told the justices in a court filing for his state.

Biden and Harris formally introduced newly nominated and appointed members of their administration from Wilmington, Delaware, Friday afternoon, showing off several familiar faces, be it from the Obama administration or from Capitol Hill.

For director of the White House Domestic Policy Council, a position which does not require Senate confirmation, Biden picked Susan Rice. Rice served as U.S. ambassador to the United Nations and later as national security adviser in the Obama administration.

In her remarks, Rice laid out the path of her ancestors on both sides who overcame adversity -- a paternal great grandfather who was born a slave in South Carolina and maternal grandparents who immigrated from Jamaica with no education and worked to send their children to college, leading to her mother’s role in creating the Pell Grant.

“Now at the foot of yet another bridge between crisis and opportunity, I'm honored and excited to take on this role. Joe Biden and Kamala Harris's vision for our future is expansive but achievable," Rice said, stressing her excitement to serve again and the need to develop policies that break down racial barriers that hold all Americans back.

Rep. Marcia Fudge, who has represented Ohio's 11th Congressional District for the last 12 years has been tapped for secretary of Housing and Urban Development and talked about the importance of housing in America and the need to give people hope amid  America’s ongoing crisis.

“Perhaps most importantly of all, we will help people believe once again that their government cares about them, no matter who they are. That we understand their problems, as the president-elect often recalls his father's words,” she said.

Biden's nominee for secretary of agriculture, Tom Vilsack, seemed to address some of the criticism of his previous tenure at USDA (he held the same Cabinet position he's nominated for throughout the Obama administration) by promising to deal with systemic inequities.

Vilsack also mentioned his support for Rep. Jim Clyburn's 10/20/30 plan, an effort the South Carolina congressman said aims to help counties that had a poverty level of more 20% for more than three decades. Those communities would receive at least 10% of federal funds from a specific program. When asked in 2019 if he considered the measure a form of reparations, Clyburn said the measure "absolutely" is.

Biden's pick for secretary of veterans affairs, Dennis McDonough, former President Barack Obama's White House chief of staff, pledged to make the department more inclusive to all veterans, particularly women, veterans of color and members of the LGBTQ community.

Biden's appointed Katherine Tai to U.S. trade representative, who began by recalling her parents' immigrant story of her father, a researcher at Walter Reed, and her mother, who still works at the National Institutes of Health developing treatments for opioid addictions. She also stressed the role trade can play to create opportunities and lift people out of poverty and the need to rebuild relationships around the globe.
