Many of those challenges have been tossed out by judges, some within hours of their filing.
A week after his Democratic rival clinched the election, Trump's lawsuits have made little headway in the courts while Biden has received congratulatory calls from world leaders and forged ahead with work on forming his Cabinet.
'It is very important that Joe Biden have access to the intelligence briefings to make sure that he is prepared, ' Hutchinson said.
"It probably sets him up for a strong run in 2024".
Mr Biden's pick for White House chief of staff, Mr Ron Klain, has said that a rapid transition is necessary to ensure the government is prepared to roll out a potential Covid-19 vaccine early next year.
Democrats say this could have a damaging impact both on national security and on the grave and mounting challenges posed by the coronavirus pandemic.
Biden further solidified his victory on Friday as results from Edison Research showed him winning Georgia, giving him a final tally of 306 Electoral College votes, far more than the 270 needed to be elected president and above Trump's 232. The American people did that, he told NBC. Now, Trump is refusing to concede his loss as he believes he was wronged by the democratic process.
There has been no widespread fraud in the 2020 election. "Donald Trump lost what, by any evidence we have so far, was a free and fair election".

"I will not go - this administration will not be going to a lockdown".
More than 10,000 Trump supporters rallied in Washington on Saturday to back his claims of fraud - massing in Washington's Freedom Plaza before marching to the Supreme Court in a raucous atmosphere.
After dark, groups of Trump supporters and counter-protesters clashed on the streets, scuffling and throwing punches.
City police said they'd made at least 20 arrests - three of which involved assaults - but a total count wasn't expected until Sunday morning.
