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.

While the U.S. Supreme Court has twice refused to hear pro-Trump challenges to the 2020 elections, a federal judge in Wisconsin on Saturday joined the chorus of rulings against Trump in his effort to use the courts to invalidate Biden’s victory.

“This Court has allowed plaintiff the chance to make his case and he has lost on the merits,” wrote U.S. District Court Judge Brett H. Ludwig, a Trump appointee. Ludwig noted that the president had asked “that the Rule of Law be followed,” and he declared in response: “It has been.”

The ruling comes just one day after the U.S. Supreme Court refused to consider an election challenge brought by the Texas attorney general contesting the way elections were run in four states, including Wisconsin. Trump had called that case “the big one,” because he thought it held the best hopes for him of re-litigating the 2020 contest in court.

This latest ruling marks nearly 50 losses for the president  in cases brought by him and his supporters since election day. In Wisconsin, where Biden won by more than 20,000 votes, Trump asked for 221,000 absentee and mail-in ballots to be excluded on the grounds they were collected in ways not laid out by the state legislature. And the president argued that the legislature should be afforded the chance to select an alternate slate of electors.

Ludwig’s 23-page opinion gave wide latitude to Trump -- finding that the president had standing to file his election challenge and was not too late to raise his concerns about the way the election was conducted. But the outcome of the case was the same as rulings in other battleground states -- that Biden’s victory was attained legally and should not be thrown to a legislature to upend.

The president, Ludwig wrote, “has not proved” that state election officials violated his rights. “To the contrary, the record shows Wisconsin’s Presidential Electors are being determined in the very manner directed by the Legislature, as required by Article II, Section 1 of the Constitution.”

Ludwig further noted that if he followed the demands set out in Trump’s lawsuit, “any disappointed loser in a Presidential election, able to hire a team of clever lawyers, could flag claimed deviations from the election rules and cast doubt on the election results. This would risk turning every Presidential election into a federal court lawsuit over the Electors Clause.”

The Trump campaign has not yet responded to requests for comment.

At the moment the federal ruling was handed down, the Wisconsin Supreme Court was hearing arguments on a separate challenge to a recount of votes in the state, which had failed in a lower court.
