A blistering ruling from Third District’s Stephanos Bibas – a Trump-appointed judge – said “free, fair elections are the lifeblood of our democracy.”
“Charges of unfairness are serious,” he said in his ruling on Friday. "But calling an election unfair does not make it so. Charges require specific allegations and then proof. We have neither here."
One of his lawyers, Jenna Ellis, said they will take their case to the Supreme Court.
Earlier on Friday Mr Trump, currently playing golf, tweeted en route to his Virginia course that Joe Biden must first “prove” that all of his “ridiculous” 80 million votes were obtained legally, before claiming the White House.
Mr Trump’s admission on Thursday that he would leave if Mr Biden won the electoral college made headlines worldwide - despite the fact that it should not have been necessary to state.
The president on Friday appeared irritated by the response, and tweeted: “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!”
The president’s legal team, led by Rudy Giuliani, are continuing to challenge results in the courts, but their hopes - faint from the start - are fading. They have had more than 35 cases dismissed so far.
