Over a month after President-elect Joe Biden defeated him in the 2020 election, outgoing President Donald Trump still refuses to acknowledge the reality of his loss.

The President has frequently amplified lies that Democrats coordinated widespread voter fraud to tip the election to Biden. The dozens of legal cases filed on Trump's behalf to overturn the election or limit vote counting have resulted in nearly 60 losses in court, with only one win.

Twice, the Supreme Court—on which three Trump-appointed Justices sit—has denied standing to the Trump campaign's arguments to de-certify the vote in multiple swing states.

Though 126 Republican lawmakers signed an amicus briefing in support of the President's most recent Supreme Court litigation to no avail, the failure of Trump's efforts is becoming even more inevitable—and now it seems that Republican support is waning.

On Tuesday, Senate Majority Leader Mitch McConnell (R-KY) acknowledged Biden as the President-elect one day after electors across the country met to cast 306 electoral votes for him—well over the 270 required for Biden to take the White House.

The Senate Majority Leader said:

"Many millions of us had hoped the presidential election would yield a different result, but our system of government has processes to determine who will be sworn in on January the 20th. The electoral college has spoken. Today, I want to congratulate President-elect Joe Biden."

With nearly every avenue to overturn the election exhausted, a faction of Trump's supporters are hoping for the House and Senate to vote against national certification when Vice President Mike Pence reads the electoral votes aloud on January 6.

But as the top Senate Republican acknowledges Biden's victory, the undoing of the election through Congress—especially with a Democratic House—is practically a pipe dream.

Trump responded to the news on Twitter, where he accused McConnell of giving up too soon.

Over the course of Trump's four years in the White House, McConnell's hold over the Senate has been a crucial asset to the Trump administration, with McConnell heading the confirmation process of Trump's judicial nominees to fill more than a hundred vacancies, left open by McConnell's refusal to bring former President Barack Obama's judicial nominees to the floor.

McConnell amplified disinformation surrounding the Russia investigation and Trump's impeachment, but following Trump into the effort of subverting a U.S. election was a step too far.

People mocked Trump's disappointment on Twitter and fact checked claims about his vote totals.

Trump's supporters, however, echoed his frustration with McConnell.

President-elect Joe Biden and Vice President-elect Kamala Harris will be inaugurated on January 20th.
