States have until Dec. 8 to resolve election disputes, including recounts and court contests over the results. Members of the Electoral College meet Dec. 14 to finalize the outcome.

Generally, Justice Department policy is "not to conduct overt investigations, including interviews with individual voters, until after the outcome of the election allegedly affected by the fraud is certified."

But Barr argues, in the memo, that concerns such acts could inadvertently impact an election, are minimized once voting has concluded and that, in some cases, investigations could not be delayed until the election is certified.

A Justice Department official said Barr had not been asked by Trump, anyone else at the White House or any lawmakers to issue the memo.

Biden campaign attorney Bob Bauer said in a statement that it is:

"deeply unfortunate that Attorney General Barr chose to issue a memorandum that will only fuel the 'specious, speculative, fanciful or far-fetched claims' he professes to guard against."

"Those are the very kind of claims that the president and his lawyers are making unsuccessfully every day, as their lawsuits are laughed out of one court after another. But, in the end, American democracy is stronger than any clumsy and cynical partisan political scheme."

The governor's promise to disrupt distribution plans has earned him a slew of criticism on social media.

Fox News weather presenter Janice Dean accused Cuomo of being "one of the worst leaders of all time." Dean has been one of the governor's most vocal critics this year, after both her father and mother-in-law passed away in New York nursing homes during the Covid-19 pandemic. She has linked the deaths to a controversial order from Cuomo forcing care homes to accept positive Covid-19 cases.

The Dow Jones Industrial Average opened up 1,600 points, or 5.6 percent, hitting an all-time high before retreating slightly. The broader S&P 500 also hit a record high, jumping 3.7 percent. The tech-heavy Nasdaq Composite grew 1.3 percent.

The 90 percent effective rate announced by Pfizer and BioNTech was better than the stock market was expecting. According to Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases, a vaccine that is 50 percent to 60 percent effective would be acceptable.

Pfizer CEO Albert Bourla said the company expects to have 1.3 billion doses of the vaccine available globally next year, on top of 50 million doses this year. Two separate production lines, one in the United States and one in Europe, will make the vaccine.

Pfizer's stock soared by more than 14 percent at the opening bell.

A poll worker with the Clark County Elections Department in Nevada is blowing the whistle in a signed affidavit making appalling allegations of electoral fraud that they claim has occurred in the key battleground state.

"We were told by (my team leader), and two other assistants to advise people who wanted to register to vote and did not have the proper Nevada ID/Driver's License, that they could go out in the parking lot and make an appointment with the DMV to get a Nevada ID/Driver's License, and then bring in proof of their appointment confirmation (either a paper copy or show it on their phone to us) and then they could be registered," the whistleblower said in their deposition.

"They were then permitted to vote with a provisional ballot, even though their appointments were not until January of 2021. We were told this was being allowed all over the Valley, at all polling places," they continued.

"I personally witnessed two people handing multiple unopened mail in ballot envelopes to two other people who then opened and filled out the ballots against the side of the Biden/Harris van. The same two people who marked the ballots then put the marked ballots in official pink and white envelopes. These individuals were not poll workers," they explained.

The whistleblower added that eventually "there were 5 or 6 additional people who formed a human wall, which moved as I walked by, apparently in an attempt to block my view of the four people who were opening envelopes, marking ballots, and placing those ballots in the pink and white return envelopes." This was ignored by the team leader when the whistleblower reported the violation through the proper channels.

"I regularly saw people walking in with multiple ballots. We were not allowed to talk to the monitors or observers. We were not supposed to say anything ever to the observers," the whistleblower said.

The whistleblower's entire deposition can be seen below, with Sean Davis of The Federalist noting that Nevada's democrat attorney general Aaron Ford has not taken any concrete action to investigate these explosive claims at the present time:
