A "Rogue staffer" has alleged that US President Donald Trump "won't leave the White House in January" despite reportedly losing the election to Joe Biden.

The allegations which emanated from an unverified Twitter account called Rogue POTUS Staff, which is operated by a group known as "Anonymous patriots" also alleged that Trump has "told aides to 'write his name on everything.'" in the White House

The accusation was tweeted out on Monday November 9, after Trump lost his presidential battle to Joe Biden and claimed it was a "rigged" election even though there is not yet any known evidence of widespread voter fraud.

Trump has refused to concede and has started lawsuits in the states he lost to Joe Biden.

The tweet reads: "Not announced yet, but there will be a press briefing at White House at 3:00 pm today to talk about the President's plans.

"He will basically be saying that he has no intentions of leaving in Jan. He's been using the phrase 'write my name on everything in the room.'"

The tweet then adds that the event would be held at Whyte House Monograms in Chevy Chase, a small family oriented monogramming business.
