Trump says Biden can only enter the White House as president if he can 'prove' his 'ridiculous 80M votes' were NOT 'obtained by fraud' as he appears to row back peaceful transition claims

President Donald Trump said on Friday that Joe Biden can only enter the White House if he can prove his votes are not 'fraudulent' - a step back from Thursday's admission he would cede the residence for his Democratic rival in a peaceful transfer of power.

'Biden can only enter the White House as President if he can prove that his ridiculous “80,000,000 votes” were not fraudulently or illegally obtained. When you see what happened in Detroit, Atlanta, Philadelphia & Milwaukee, massive voter fraud, he’s got a big unsolvable problem!,' Trump tweeted.

Trump has refused to concede the election despite Biden's massive lead in the popular vote and the electoral college. Several foreign leaders have recognized Biden as the president-elect, calling to congratulate him, and so have several top business leaders, including some who are close to Trump.

Additionally, the president's campaign has shown no evidence of massive voter fraud. State officials have also said the election was smoothly run. Trump's legal cases have gone no where. A hand recount of ballots in Georgia confirmed Biden's win there.

Trump's legal team, led by Rudy Giuliani, has tried to move the ball forward. But Giuliani's bizarre press conference at the Republican National Committee headquarters on Monday raised more questions than answers and a hearing-style event in Gettysburg, Pennsylvania, on Wednesday, which Trump called into, revealed no evidence of voter fraud in that state.

Despite it all, Trump continues to proclaim he's the victor.

But the president - just one day before on Thanksgiving - said he would leave the White House if the electoral college certifies Biden's victory when it meets on December 14.
