It comes days after Fox News called the state for Biden, sparking fury from Trump and his campaign.
Fox called Arizona for Biden on election night when just 73 per cent of the state's vote had been counted.
This enraged the President so much, Trump's political adviser Jason Miller called Fox News in a bid to get the network to retract the call, according to the New York Times.
The President still appears to be bitter about the call, recently tweeting that Fox News' ratings had "collapsed" because they "forgot what made them successful".
.@FoxNews daytime ratings have completely collapsed. Weekend daytime even WORSE. Very sad to watch this happen, but they forgot what made them successful, what got them there. They forgot the Golden Goose. The biggest difference between the 2016 Election, and 2020, was @FoxNews!
Despite Biden being declared the winner of the election and making a victory speech, Trump has still refused to concede that he lost.
Trump has been making, so far unsubstantiated, claims of widespread voter fraud and remains adamant he could still win the election.
Most recently, the President claimed in a series of tweets that 2.7 million votes for him had been "deleted" and hundreds of thousand had been switched from him to Biden in Pennsylvania and other states.
“REPORT: DOMINION DELETED 2.7 MILLION TRUMP VOTES NATIONWIDE. DATA ANALYSIS FINDS 221,000 PENNSYLVANIA VOTES SWITCHED FROM PRESIDENT TRUMP TO BIDEN. 941,000 TRUMP VOTES DELETED. STATES USING DOMINION VOTING SYSTEMS SWITCHED 435,000 VOTES FROM TRUMP TO BIDEN.” @ChanelRion@OANN
Republicans such as Senate Majority Leader Mitch McConnell have stood firm with Trump by supporting his refusal to concede and backing his legal challenges.
Democratic House Speaker Nancy Pelosi weighed in on Thursday to demand Republicans stop what she called an "absurd circus" and turn to combating the pandemic.
"Now that the people have expressed their views, Joe Biden has won (and) Kamala Harris will be the first woman Vice President of the United States," Pelosi said.
Political experts believe Republicans may be invoking such a strategy as a way to rile up Trump's base before two US Senate run-off elections in Georgia that will determine which party controls the chamber.
In the past two weeks, Twitter has labelled about 300,000 tweets relating to the US election as "potentially misleading", making up 0.2 per cent of election-related posts.
The social network said the labels were issued between October 27 and November 11, one week before and after the US presidential election on November 3.
Nearly half of Trump's tweets were flagged as "disputed" by the platform in the days after the election.
