During the 46-minute speech delivered in an empty room, Trump claimed that the American electoral system was “under coordinated assault and siege” by Democratic forces.
It comes amid reports that the outgoing president is trying to use his final weeks in office to protect his three oldest children from future prosecutions with preventive pardons.
A two-minute version of the video was posted on Twitter, with the full 46-minute Facebook address.
Both Twitter and Facebook placed disclaimers below the video warning of its inaccuracies.
“This may be the most important speech I’ve ever made,” Trump said.
“As President, I have no duty but to uphold the laws and the Constitution of the United States.
“That is why I am determined to defend our electoral system, which is now under a coordinated assault and siege.”
Trump said there was an “orchestrated effort to anoint a winner even as many key states were still counted.”
“We are going to defend the honesty of the vote by making sure every legal ballot is counted and no illegal vote is counted,” he said.
“It’s about ensuring that Americans can have faith in this election and in all future elections.”
Despite filing countless lawsuits in multiple states, Trump’s legal team has been unable to provide any evidence of a single case of ballot or ballot fraud.
In the electoral college, Biden obtained 306 electoral votes to Trump’s 232, an exact reversal of the president’s 2016 victory over Hillary Clinton.
“Large numbers of absentee and mailed ballots were illegally and secretly processed in Philadelphia and Allegheny County without our observers present,” Trump falsely said.
“It is not in the power of this Court to violate the Constitution,” he wrote in a withering decision.
“In the United States of America, this cannot justify the disenfranchisement of a single voter, much less of all voters in its sixth most populous state.
“Our people, laws and institutions demand more.”
Only a few Republicans in Congress have recognized Biden as president-elect, even if they are actively debating their nominees for cabinet positions.
Iowa Senator Chuck Grassley made suggestions about who Biden should nominate for secretary of agriculture, even if he did not admit that Trump had lost.
“I realize this could hurt his chances, but if Biden becomes president, he should select an Iowan or Heidi Heitkamp or Collin Peterson to be the agriculture secretary. They could do things for the AI / Midwest farmers. even in the Democratic House and the Republican Senate, “the 87-year-old senator tweeted.
At a rally in Georgia, former Trump attorneys Sidney Powell and Lin Wood told conservatives not to attend the election.
“Why would you go back and vote in another rigged election?” Mr Wood said.
“I would encourage all Georgians to make it known that they will not vote at all unless their vote is secure,” Powell said.
The results of the second round will determine who controls the balance of power in the Senate.
Polls have shown the two races are tied.
