FOX host Laura Ingraham has told her viewers that the election is over and that she'd be lying if she said Donald Trump could still win.
Speaking on her show, The Ingraham Angle, the presenter said it is now a matter of "reality" that Joe Biden will be inaugurated as president in January.
It came after President Trump yesterday announced on Twitter that he had instructed the General Services Administration and his own team to initiate the transition to the next administration.
He had previously refused to do so, insisting without evidence that Biden had won the election because of voted fraud.
Ingraham has long been among the president's most vocal supporters and since the election has frequently aired support for the claims.
Speaking last night, she said: “As unpleasant and disappointing as these past three weeks have been to so many of us, as much as we wish things were different, this is where things stand tonight.
“Unless the legal situation changes in a dramatic and frankly an unlikely manner, Joe Biden will be inaugurated on January 20.
“Now, to say this does not mean I don’t think that the selection was rife with problems and potential fraud.
"And to say this does not constitute being a sellout to the conservative populist movement that I’ve been fighting for for 25 years.
"And it does not mean that I disagree at all with the president’s right and obligation to pursue all legitimate legal challenges to this outcome.”
Recent weeks have seen Trump and his supporters attack Fox News over its coverage, and particularly its decision to call the swing state of Arizona in Biden's favour earlier than most other networks.
Tweeting after the election, Trump wrote: "@FoxNews daytime ratings have completely collapsed. Weekend daytime even WORSE. Very sad to watch this happen.
"The biggest difference between the 2016 Election, and 2020, was @FoxNews!"
'I'D BE LYING IF I SAID TRUMP COULD WIN'
Ingraham continued: “To say this constitutes living in reality. And if I offered you a false reality, if I told you that there was an excellent, phenomenal chance that the Supreme Court was going to step in and deliver a victory to President Trump, I'd be lying to you.”
She added that there remained an "enormous amount for us to be hopeful about".
“Thanks to President Trump, we have seen the amazing results that are possible with his America First agenda,” she said.
Prior to Trump's announcement yesterday, a number of conservative commentators had voiced dismay at a press conference by his legal team at which they failed to present substantive evidence of voter fraud.
Speaking on his radio show, host Rush Limbaugh, another long-time supporter of the president's, said: "You call a gigantic press conference like that — one that lasts an hour — and you announce massive bombshells, then you better have some bombshells.
"They promised blockbuster stuff and then nothing happened, and that’s just, it’s not good."
Another ally, former New Jersey governor Chris Christie, said on Sunday: "The president has had the opportunity to access the courts.

"The conduct of the president's legal team has been a national embarrassment.
"Notice, they won't [allege fraud] inside the courtroom. They [do it] it outside the courtroom, but when they go inside the courtroom, they don't plead fraud, they don't argue fraud.
"We cannot continue to act as if something happened here that didn't happen."
