Supporters of President Donald Trump are hoping that e-mails found on a laptop allegedly belonging to former Vice President Joe Biden's son, Hunter Biden, will be the "October surprise" that derails the older Biden's presidential campaign. The New York Post, owned by Fox News' Rupert Murdoch, published that story after receiving an alleged copy of Hunter Biden's hard drive from former New York City Mayor Rudy Giuliani — and more than 50 intelligence officials, according to Politico's Natasha Bertrand, have signed a letter saying that the story has the markings of a Kremlin propaganda operation.

Bertrand explains, "While the letter's signatories presented no new evidence, they said their national security experience had made them 'deeply suspicious that the Russian government played a significant role in this case' and cited several elements of the story that suggested the Kremlin's hand at work.'"

Intel experts who signed the letter range from Russ Travers, who served as acting director for the National Counterterrorism Center, to Rick Ledgett, former deputy director of the National Security Agency. Former Central Intelligence Agency directors or acting directors who signed the letter include John O. Brennan, Leon Panetta, Gen. Michael Hayden, John McLaughlin and Michael Morell.

The letter reads, "If we are right, this is Russia trying to influence how Americans vote in this election — and we believe strongly that Americans need to be aware of this."

The intel experts also said, "We want to emphasize that we do not know if the e-mails, provided to the New York Post by President Trump's personal attorney, Rudy Giuliani, are genuine or not — and that we do not have evidence of Russian involvement… (But) there are a number of factors that make us suspicious of Russian involvement…. Such an operation would be consistent with Russian objectives, as outlined publicly and recently by the intelligence community, to create political chaos in the United States and to deepen political divisions here — but also, to undermine the candidacy of former Vice President Biden and thereby help the candidacy of President Trump."
